[PATCH] RTC framework driver for CMOS RTCs This is an "RTC framework" driver for the "CMOS" RTCs which are standard on PCs and some other platforms. That's MC146818 compatible silicon. Advantages of this vs. drivers/char/rtc.c (use one _or_ the other, only one will be able to claim the RTC irq) include: - This leverages both the new RTC framework and the driver model; both PNPACPI and platform device modes are supported. (A separate patch creates a platform device on PCs where PNPACPI isn't configured.) - It supports common extensions like longer alarms. (A separate patch exports that information from ACPI through platform_data.) - Likewise, system wakeup events use "real driver model support", with policy control via sysfs "wakeup" attributes and and using normal rtc ioctls to manage wakeup. (Patch in the works. The ACPI hooks are known; /proc/acpi/alarm can vanish. Making it work with EFI will be a minor challenge to someone with e.g. a MiniMac.) It's not yet been tested on non-x86 systems, without ACPI, or with HPET. And the RTC framework will surely have teething pains on "mainstream" PC-based systems (though must embedded Linux systems use it heavily), not limited to sorting out the "/dev/rtc0" issue (udev easily tweaked). Also, the ALSA rtctimer code doesn't use the new RTC API. Otherwise, this should be a no-known-regressions replacement for the old drivers/char/rtc.c driver, and should help the non-embedded distros (and the new timekeeping code) start to switch to the framework. Note also that any systems using "rtc-m48t86" are candidates to switch over to this more functional driver; the platform data is different, and the way bytes are read is different, but otherwise those chips should be compatible.

RTC: Disable CONFIG_RTC_CLASS from being built as a module The RTC subsystem has a number of accessors that are available via include/linux/rtc.h. However many of these interfaces are not available for use if CONFIG_RTC_CLASS=m. So in order to support wider use of the RTC in the kernel, I'm removing the tristate config option for a bool, so that code can easily be conditionalized if the RTC class is present or not.

rtc: move mc146818 helper functions out-of-line The mc146818_get_time/mc146818_set_time functions are rather large inline functions in a global header file and are used in several drivers and in x86 specific code. Here we move them into a separate .c file that is compiled whenever any of the users require it. This also lets us remove the linux/acpi.h header inclusion from mc146818rtc.h, which in turn avoids some warnings about duplicate definition of the TRUE/FALSE macros.

rtc: suspend()/resume() restores system clock RTC class suspend/resume support, re-initializing the system clock on resume from the clock used to initialize it at boot time. - The reinit-on-resume is hooked to the existing RTC_HCTOSYS config option, on the grounds that a clock good enough for init must also be good enough for re-init. - Inlining a version of the code used by ARM, to save and restore the delta between a selected RTC and the current system wall-clock time. - Removes calls to that ARM code from AT91, OMAP1, and S3C RTCs. This means that systems using those RTCs across suspend/resume will likely want to change their kernel configs to enable RTC_HCTOSYS. If HCTOSYS isn't using a second RTC (with battery?), this changes the system's initial date from Jan 1970 to the epoch this hardware uses: 1998 for AT91, 2000 for OMAP1 (assuming no split power mode), etc. This goes on top of the patch series removing "struct class_device" usage from the RTC framework.

[PATCH] RTC class: Kconfig improvements Small updates to make the RTC class Kconfig text be more informative.

rtc: add generic nvmem support Many RTCs have an on board non volatile storage. It can be battery backed RAM or an EEPROM. Use the nvmem subsystem to export it to both userspace and in-kernel consumers. This stays compatible with the previous (non documented) ABI that was using /sys/class/rtc/rtcx/device/nvram to export that memory. But will warn about the deprecation.

rtc: kconfig: fix RTC_INTF defaults connected to RTC_CLASS Commit 6b8029fab641 ("rtc: kconfig: remove unnecessary dependencies") removed various 'depends on RTC_CLASS' dependencies but also removed a few 'default RTC_CLASS' statements, which actually changed default behavior. This resulted in the various RTC interfaces (sysfs, proc, dev) all being disabled by default, even when RTC_CLASS is enabled: # CONFIG_RTC_INTF_SYSFS is not set # CONFIG_RTC_INTF_PROC is not set # CONFIG_RTC_INTF_DEV is not set which is different from previous behavior (all of these where enabled.) To fix, add back the 'default RTC_CLASS' statments to each of the RTC_INTF_* options. I noticed this because some RTC tests started failing on my TI OMAP platforms because /dev/rtc0 was not present anymore, even though the driver was present and RTC_CLASS was enabled.

RTC: Revert UIE emulation removal Uwe pointed out that my alarm based UIE emulation is not sufficient to replace the older timer/polling based UIE emulation on devices where there is no alarm irq. This causes rtc devices without alarms to return -EINVAL to UIE ioctls. The fix is to re-instate the old timer/polling method for devices without alarm irqs. This patch reverts the following commits: 042620a018afcfba1d678062b62e46 - Remove UIE emulation 1daeddd5962acad1bea55e524fc0fa - Cleanup removed UIE emulation declaration b5cc8ca1c9c3a37eaddf709b2fd3e1 - Remove Kconfig symbol for UIE emulation The emulation mode will still need to be wired-in with a following patch before it will work.

rtc: ds1307: add basic support for ds1341 chip This adds support for reading and writing date/time from/to ds1341 chip. ds1341 chip has other features - alarms, input clock (can be used instead of intercal oscillator for better accuracy), output clock ("square wave generation"). However, not all of that is available at the same time. Same chip pins, CLKIN/nINTA and SQW/nINTB, can be used either for input/output clocks, or for alarm interrupts. Role of these pins on particular board depends on hardware wiring. We can add device tree properties that describe if each of pins is wired as clock, or as interrupt, or left unconnected, and enable support for corresponding functionality based on that. But that is cumbersome, requires hardware for testing, and has to deal with bit enabling/disabling output clock also affects which pins alarm interrupts are routed to. Another factor is that there are hardware setups (i.e. ZII RDU2) that power DS1341 from SuperCap, which makes power saving critical. For such setups, kernel driver should leave register bits that control mentioned pins in the state configured by bootloader. Given all that, it was decided to limit support to "only date/time" for now. That is enough for common use case. Full (and cumbersome) implementation can be added later if ever needed.

This driver supports M41T8[0-4] and M41ST8[457]. The old m41t00 driver supports M41T00, M41T81 and M41T85(M41ST85). While the M41T00 chip is now supported by rtc-ds1307 driver, this driver does not include support for the chip.

This includes voltage regulators, Dual slot memory card tranceivers and real-time clock(RTC). The support for RTC is integrated with this driver only; it is not separate module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic" (1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too. The battery keeps the RTC active over power off, so once you set clock (rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will behave as expected.

rtc: Ramtron FM3130 RTC support Ramtron FM3130 is a chip with two separate devices inside, RTC clock and FRAM. This driver provides only RTC functionality. This chip is met in lots of custom boards with AT91SAMXXXX CPU I work with, is cheap and in no way better or worse than any other RTC on market. While it is mostly met on much smaller devices, I think it is great to have it supported in Linux.

rtc: add stand-alone driver for RX8025 chip Add support for the Epson RX-8025SA/NB RTC chips. It includes support for alarms, periodic interrupts (1 Hz) and clock precision adjustment. For clock precision adjustment, the SYSFS file "clock_adjust_ppb" gets created in "/sys/class/rtc/rtcX/device". It permits to set and get the clock adjustment in ppb (parts per billion), e.g.: # echo -183000 > /sys/class/rtc/rtc0/device/clock_adjust_ppb # cat /sys/class/rtc/rtc0/device/clock_adjust_ppb -183000 This allows to compensate temperature dependent clock drifts. According to the RX8025 SA/NB application manual the frequency and temperature characteristics can be approximated using the following equation: df = a * (ut - t)**2 df: Frequency deviation in any temperature a : Coefficient = (-35 +-5) * 10**-9 ut: Ultimate temperature in degree = +25 +-5 degree t : Any temperature in degree Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Sergei Poselenov <sposelenov@emcraft.com> Signed-off-by: Yuri Tikhonov <yur@emcraft.com> Signed-off-by: Dmitry Rakhchev <rda@emcraft.com> Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

rtc: avoid legacy drivers with generic framework Kconfig tweaks to help reduce RTC configuration bugs, by avoiding legacy RTC drivers when the generic RTC framework is enabled: - If rtc-cmos is selected, disable the legacy rtc driver; - When using generic RTC on x86, enable rtc-cmos by default; - In the old "chardev RTC" section of Kconfig, add a comment warning people off these (seven) legacy RTC drivers when the generic framework is in use. People can still use the legacy drivers if they want (or need) to. This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver. Ideally it would be a full list of platforms where it works, not a partial list of ones where it won't. Or better yet, it would depend on a "HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a Kconfig style guideline lurking there.

Here we move them into a separate .c file that is compiled whenever any of the users require it. This also lets us remove the linux/acpi.h header inclusion from mc146818rtc.h, which in turn avoids some warnings about duplicate definition of the TRUE/FALSE macros.

alpha: Reorganize rtc handling Discontinue use of GENERIC_CMOS_UPDATE; rely on the RTC subsystem. The marvel platform requires that the rtc only be touched from the boot cpu. This had been partially implemented with hooks for get/set_rtc_time, but read/update_persistent_clock were not handled. Move the hooks from the machine_vec to a special rtc_class_ops struct. We had read_persistent_clock managing the epoch against which the rtc hw is based, but this didn't apply to get_rtc_time or set_rtc_time. This resulted in incorrect values when hwclock(8) gets involved. Allow the epoch to be set from the kernel command-line, overriding the autodetection, which is doomed to fail in 2020. Further, by implementing the rtc ioctl function, we can expose this epoch to userland. Elide the alarm functions that RTC_DRV_CMOS implements. This was highly questionable on Alpha, since the interrupt is used by the system timer. Signed-off-by: Richard Henderson <rth@twiddle.net>

rtc: add driver for DS1685 family of real time clocks This adds a driver for the Dallas/Maxim DS1685-family of RTC chips. It supports the DS1685/DS1687, DS1688/DS1691, DS1689/DS1693, DS17285/DS17287, DS17485/DS17487, and DS17885/DS17887 RTC chips. These chips are commonly found in SGI O2 and SGI Octane systems. It was originally derived from a driver patch submitted by Matthias Fuchs many years ago for use in EPPC-405-UC modules, which also used these RTCs. In addition to the time-keeping functions, this RTC also handles the shutdown mechanism of the O2 and Octane and acts as a partial NVRAM for the boot PROMS in these systems. Verified on both an SGI O2 and an SGI Octane.

rtc: add support for STK17TA8 chip This patch adds support for the Simtek STK17TA8 timekeeping chip. The STK17TA8 is quite similar to the DS1553, but differs in register layout and in various control bits in the registers. I chose to make this a new driver to avoid confusion in the code and to not get lost in #ifdefs.

rtc: da9063: Add DA9062 RTC capability to DA9063 RTC driver Add DA9062 RTC support into the existing DA9063 RTC driver component by using generic access tables for common register and bit mask definitions. The following change will add generic register and bit mask support to the DA9063 RTC. The changes are slightly complicated by requiring support for three register sets: DA9063-AD, DA9063-BB and DA9062-AA. The following alterations have been made to the DA9063 RTC: - Addition of a da9063_compatible_rtc_regmap structure to hold all generic registers and bitmasks for this type of RTC component. - A re-write of struct da9063 to use pointers for regmap and compatible registers/masks definitions - Addition of a of_device_id table for DA9063 and DA9062 defaults - Refactoring functions to use struct da9063_compatible_rtc accesses to generic registers/masks instead of using defines from registers.h - Re-work of da9063_rtc_probe() to use of_match_node() and dev_get_regmap() to provide initialisation of generic registers and masks and access to regmap Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com>

rtc: Disable EFI rtc for x86 commit da167ad7638759 ("rtc: ia64: allow other architectures to use EFI RTC") inadvertently introduced a regression for x86 because we've been careful not to enable the EFI rtc driver due to the generally buggy implementations of the time-related EFI runtime services. In fact, since the above commit was merged we've seen reports of crashes on 32-bit tablets, https://bugzilla.kernel.org/show_bug.cgi?id=84241#c21 Disable it explicitly for x86 so that we don't give users false hope that this driver will work - it won't, and your machine is likely to crash.

rtc: Add support for RTCs on Wolfson WM831x devices The WM831x series of PMICs contain RTC functionality. The hardware provides a 32 bit counter incrementing at 1Hz together with a per tick interrupt and an alarm value. For simplicity the driver chooses to define the epoch for the counter as the Unix epoch - if required platform data can be used in future to customise this. When powered on from a completely cold state the RTC reports that it has not been configured - when this happens an error is returned when attempting to read the RTC in order to avoid use of values we know to be invalid. The hardware also provides security features which mean that it can ignore attempts to set the RTC time in certain circumstances, most notably if the RTC is written to too often. These errors are detected by verifying the written RTC value.

rtc/tpo: Driver to support rtc and wakeup on PowerNV platform The patch implements the OPAL rtc driver that binds with the rtc driver subsystem. The driver uses the platform device infrastructure to probe the rtc device and register it to rtc class framework. The 'wakeup' is supported depending upon the property 'has-tpo' present in the OF node. It provides a way to load the generic rtc driver in in the absence of an OPAL driver. The patch also moves the existing OPAL rtc get/set time interfaces to the new driver and exposes the necessary OPAL calls using EXPORT_SYMBOL_GPL.

rtc: pxa: convert to use shared sa1100 functions Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a superset of functionality. Having 2 drivers sharing the same memory resource is not allowed by the driver model if resources are properly declared. This problem was avoided by not adding memory resources to the SA1100 RTC driver, but that prevents clean-up of the SA1100 driver. This commit converts the PXA RTC to use the exported SA1100 RTC functions. Now the sa1100-rtc and pxa-rtc devices are mutually exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

MIPS: Loongson: Naming style cleanup and rework Currently, code of Loongson-2/3 is under loongson directory and code of Loongson-1 is under loongson1 directory. Besides, there are Kconfig options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is very ugly and confusing. Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

drivers/rtc/rtc-sirfsoc.c: add rtc drivers for CSR SiRFprimaII and SiRFatlasVI On CSR SiRFprimaII/atlasVI, there is a programmable 16-bit divider (RTC_DIV) that divides the input 32.768KHz clock to the frequency that users need (E.g. 1 Hz). The divided real-time clock will be used to drive a 32-bit counter (RTC_COUNTER) that provides users with the actual time. In each cycle of the divided real-time clock, there is a Hertz interrupt generated to the RISC. Users can also configure an alarm (RTC_ALARM). When RTC_COUNTER matches the alarm, there will be an alarm interrupt generated to the RISC. The system RTC can generate an alarm wake-up signal to notify the power controller to wake up from power saving mode.
