Currently cpu_is_omap3517() actually detects any device in the AM35x
family (3517 and no-SGX version 3505.) To make it more clear what is
being detected, convert the names from 3517 to AM35xx.
This adds a new soc_is_am35xx() which duplicates the cpu_is_omap3517().
In order to avoid cross-tree dependencies with clock-tree changes,
cpu_is_omap3517() is left until the clock changes are merged,
at which point cpu_is_omap3517() will be completely removed.

[tony@atomide.com: change to use soc_is_omap instead]
Signed-off-by: Tony Lindgren <tony@atomide.com>
There are several checks for AM35x devices done using
if (cpu_is_omap3517() || cpu_is_omap3505())
However, since the 3505 is just a 3517 without an SGX, the 3505 check
is redundant because cpu_is_omap3517() will always be true whenever
cpu_is_omap3505() is true. From <plat/cpu.h>:
#define cpu_is_omap3505() (cpu_is_omap3517() && !omap3_has_sgx())
Therefore, remove the redunant 3505 checks. This helps move towards
removal of SoC detection that depends on specific IP detection.

Each irq_chip for the main interrupt controller has offsets set for irq
masking registers, which added to respective base results in a pointer
to appropriate hardware register. However this is not correct for
INTC_CONTROL as there is only one INTC_CONTROL register. This does not
cause problems because generic ack code is never called, but remove

Current OMAP code supports couple of clocksource options based
on compilation flag (CONFIG_OMAP_32K_TIMER). The 32KHz sync-timer
and a gptimer which can run on 32KHz or system clock (e.g 38.4 MHz).
So there can be 3 options -
1. 32KHz sync-timer
2. Sys_clock based (e.g 13/19.2/26/38.4 MHz) gptimer
3. 32KHz based gptimer.
The optional gptimer based clocksource was added so that it can
give the high precision than sync-timer, so expected usage was 2
and not 3.
Unfortunately option 2, clocksource doesn't meet the requirement of
free-running clock as per clocksource need. It stops in low power states
when sys_clock is cut. That makes gptimer based clocksource option
useless for OMAP2/3/4 devices with sys_clock as a clock input.
So, in order to use option 2, deeper idle state MUST be disabled.
Option 3 will still work but it is no better than 32K sync-timer
based clocksource.
We must support both sync timer and gptimer based clocksource as
some OMAP based derivative SoCs like AM33XX does not have the
sync timer.
Considering above, make sync-timer and gptimer clocksource runtime
selectable so that both OMAP and AMXXXX continue to use the same code.
And, in order to precisely configure/setup sched_clock for given
clocksource, decision has to be made early enough in boot sequence.
So, the solution is,
Use standard kernel parameter ("clocksource=") to override
default 32k_sync-timer, in addition to this, we also use hwmod database
lookup mechanism, through which at run-time we can identify availability
of 32k-sync timer on the device, else fall back to gptimer.
Also, moved low-level SoC specific init code to respective files,
(mach-omap1/timer32k.c and mach-omap2/timer.c)

Depending on the bootloader, passing command-line arguments
with spaces may have issues. Some bootloaders doesn't seem
to pass along the quotes, passing only 'gp' part of the string,
which leads to wrong override configuration.
The only affected kernel parameter configuration for OMAP family
is "clocksource=", used to override kernel clocksource.
So this patch changes "gp timer" => "gp_timer", for clockevent,
clocksource and timer irq_handler.

irrespective of whether error occurred while initializing 32k sync
counter as a kernel clocksource or not and execution will never
fallback to mpu_timer clocksource init code.
This patch adds check for return value from function
omap_init_clocksource_32k(), and fallback to omap_mpu_timer_init()
in case of failure/error from omap_init_clocksource_32k().

Merge tag 'omap-devel-c-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into devel-hwmod-data
Some OMAP IP block data additions for 3.5, along with a
fix for a longstanding watchdog timer integration problem.
platform_device pdev can be NULL if CONFIG_MMC_OMAP_HS is not set.
Add check for NULL pointer. while at it move the duplicated functions
to omap4-common.c
Fixes the following boot crash seen with omap4sdp and omap4panda
when MMC is disabled.

Without runtime PM enabled, hwmod needs to leave all IP blocks in an
enabled state by default so any driver access to the HW will succeed.
This is accomplished by seting the postsetup_state to enabled for all
hwmods during init when runtime PM is disabled.
Currently, we have a special case for WDT in that its postsetup_state
is always set to disabled. This is done so that the WDT is disabled
and the timer is disarmed at boot in case there is no WDT driver.
This also means that when runtime PM is disabled, if a WDT driver *is*
built in the kernel, the kernel will crash on the first access to the
WDT hardware.
We can't simply leave the WDT module enabled, because the timer is
armed by default after reset. That means that if there is no WDT
driver initialzed or loaded before the timer expires, the kernel will
reboot.
To fix this, a custom reset method is added to the watchdog class of
omap_hwmod. This method will *always* disarm the timer after hwmod
reset. The WDT timer then will only be rearmed when/if the driver is
loaded for the WDT. With the timer disarmed by default, we no longer
need a special-case for the postsetup_state of WDT during init, so it
is removed.
Any platforms wishing to ensure the watchdog remains armed across the
entire boot boot can simply disable the reset-on-init feature of the
watchdog hwmod using omap_hwmod_no_setup_reset().
Tested on 3530/Overo, 4430/Panda.
NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as
documented in the TRM (and what happens on OMAP3.) I noticed this
because testing the HWMOD_INIT_NO_RESET feature with no driver loaded,
I expected a reboot part way through the boot, but did not see a
reboot. Adding some debug to read the counter, I verified that right
after OCP softreset, the counter is not firing. After writing the
magic start sequence, the timer starts counting. This means that the
timer disarm sequence added here does not seem to be needed for 4430,
but is technically the correct way to ensure the timer is disarmed, so
it is left in for OMAP4.
Special thanks to Paul Walmsley for helping brainstorm ideas to fix
this problem.
