12aa377bf8 clk: export some clk_hw function symbols for module drivers
clk-provider.h provides clk_hw_is_prepared(), clk_hw_is_enabled() and
clk_hw_is_prepared() but these symbols are not exported for the
modules which prevents a clock driver using them to be compiled as
a module. Export them to fix the problem.

regulator: rk808: Fix BUCK1/2 voltages on rk805
RK805 has the following voltage range for the BUCK1 and BUCK2 regulators:

From 0.7125V to 1.45V in 12.5mV steps, 1.8V, 2V, 2.2V and 2.3V

, which corresponds to the following values as per the RK805
datasheet:

000 000: 0.7125V
000 001: 0.725V
……
111 011: 1.45V
111 100: 1.8V
111 101: 2.0V
111 110: 2.2V
111 111: 2.3V

This means that the voltage range is not linear and so RK805 can not
reuse the same regulator_ops structure from RK808.

Fix it by creating a list with the correct supported voltage values
for RK805 BUCK1 and BUCK2 regulators.

Tested on a rv1108-elgin-r1 board that now correctly reports a BUCK2
voltage of 2.2V instead of the unsupported value of 1.4875V.

name and registed from differnt dapm context, and route add from
another context too. When snd_soc_dapm_add_route, the previous

ASoC: dapm: Only power up active channels from a DAI
Currently all widgets attached to a DAI link will be powered
up when the DAI is active, however this may include routes
that are not actually in use if there are unused channels
available on the DAI.

The macros for creating AIF widgets already include an entry for
slot, it is proposed to change that to channel. The effective
difference here being respresenting the logical channel index
rather than the physical slot index. The CODECs currently
using the slot entry on the DAPM_AIF macros are using it in
a manner consistent with this, the CODECs not using it just
have the field set to zero.

A variable is added to snd_soc_dapm_widget to represent
this channel index and then for each AIF widget attached to
a DAI this is compared against the number of channels on
the stream. Enabling the links for those which will be in
use. This has the nice property that the CODECs which haven't
used the slot/channel entry in the macro will function exactly
as before due to all the AIF widgets having a channel of zero
and a stream by definition having at least one channel.

ASoC: topology: fix oops/use-after-free case with dai driver
rmmod/modprobe tests expose a kernel oops when accessing the dai
driver pointer. This comes from the topology design which operates in
multiple passes. Each object removal happens at a specific iteration,
and the code checks for the iteration (order) number after the memory
containing the order was freed.

Fix this be clearing a reference to the dai driver and check its
validity to avoid dereferences.

ASoC: dapm: fix use-after-free issue with dailink sname
Commit 7620fe9161 ("ASoC: topology: fix memory leak in
soc_tplg_dapm_widget_create") fixed a memory leak issue, but
additional tests and KASAN reports show a use-after-free in soc-dapm.

The widgets are created with a kmemdup operating on a template. The
"name" string is also duplicated, but the "sname" string is not. As a
result, when the template is freed after widget creation, its sname
string is still used.

Fix by explicitly duplicating the "sname" string, and freeing it when
required.

The MAX44009 is a low-power ambient light sensor from Maxim
Integrated. It differs from the MAX44000 in that it doesn't have
proximity sensing and that it requires far less current (1 micro-amp
vs 5 micro-amps). The register mapping and feature set between the
two are different enough to require a new driver for the MAX44009.

Developed and tested with a BeagleBone Black and UDOO Neo (i.MX6SX)

* Reading lux (processed value)

* Rising and falling illuminance threshold

ASoC: rsnd: fixup MIX kctrl registration
Renesas sound device has many IPs and many situations.
If platform/board uses MIXer, situation will be more complex.
To avoid duplicate DVC kctrl registration when MIXer was used,
it had original flags.
But it was issue when sound card was re-binded, because
no one can't cleanup this flags then.

To solve this issue, commit 9c698e8481 ("ASoC: rsnd: tidyup
registering method for rsnd_kctrl_new()") checks registered
card->controls, because if card was re-binded, these were cleanuped
automatically. This patch could solve re-binding issue.
But, it start to avoid MIX kctrl.

To solve these issues, we need below.
To avoid card re-binding issue: check registered card->controls
To avoid duplicate DVC registration: check registered rsnd_kctrl_cfg
To allow multiple MIX registration: check registered rsnd_kctrl_cfg
This patch do it.

The ad7768-1 is a single channel, precision 24-bit analog to digital
converter (ADC).

This basic patch configures the device in fast mode, with 32 kSPS and
leaves the default sinc5 filter.

Two data conversion modes are made available. When data is retrieved by
using the read_raw attribute, one shot single conversion mode is set.
The continuous conversion mode is enabled when the triggered buffer
mechanism is used. To assure correct data retrieval, the driver waits
for the interrupt triggered by the low to high transition of the DRDY
pin.

74c953ca5f efi/arm64: Fix debugfs crash by adding a terminator for ptdump marker
When reading 'efi_page_tables' debugfs triggers an out-of-bounds access here:

  if (addr >= st->marker[1].start_address) {

called from:

  arch/arm64/mm/dump.c: 331
  note_page(st, addr, 2, pud_val(pud));

because st->marker++ is is called after "UEFI runtime end" which is the
last element in addr_marker[]. Therefore, add a terminator like the one
for kernel_page_tables, so it can be skipped to print out non-existent
markers.

dc3f595b66 dmaengine: at_xdmac: Fix wrongfull report of a channel as in use
atchan->status variable is used to store two different information:
 - pass channel interrupts status from interrupt handler to tasklet;
 - channel information like whether it is cyclic or paused;

This causes a bug when device_terminate_all() is called,
(AT_XDMAC_CHAN_IS_CYCLIC cleared on atchan->status) and then a late End
of Block interrupt arrives (AT_XDMAC_CIS_BIS), which sets bit 0 of
atchan->status. Bit 0 is also used for AT_XDMAC_CHAN_IS_CYCLIC, so when
a new descriptor for a cyclic transfer is created, the driver reports
the channel as in use:

if (test_and_set_bit(AT_XDMAC_CHAN_IS_CYCLIC, &atchan->status)) {
	dev_err(chan2dev(chan), "channel currently used\n");
	return NULL;
}

This patch fixes the bug by adding a different struct member to keep
the interrupts status separated from the channel status bits.

0e4c2da4f0 staging: iio: cdc: ad7152: remove driver completely
The AD7153 part has been obsoleted for some time. The AD7152 part will be
obsolete in the coming future.
Moving it out of staging doesn't make sense anymore. Which makes the driver
enter a limbo state.

This patch removes the driver completely, so that no effort is placed on
it, allowing people to focus on other parts that will still be around.

The Invensense ICM-20602 is a 6-axis MotionTracking device that
combines a 3-axis gyroscope and an 3-axis accelerometer. It is very
similar to the ICM-20608 imu which is already supported by the mpu6050
driver. The main difference is that the ICM-20602 has the i2c bus
disable bit in a separate register.

"Resource Control" is a very broad term for this CPU feature, and a term
that is also associated with containers, cgroups etc. This can easily
cause confusion.

Make the user prompt more specific. Match the config symbol name.

 [ bp: In the future, the corresponding ARM arch-specific code will be
   under ARM_CPU_RESCTRL and the arch-agnostic bits will be carved out
   under the CPU_RESCTRL umbrella symbol. ]

f38ab20b74 iio: st_accel: use ACPI orientation data
Platform-specific ST accelerometer mount matrix information can be
provided by returning a package of 6 integers from the ACPI _ONT
method. This has been seen on Acer products such as Veriton Z4860G,
Z6860G and A890, which include a ST SMO8840 sensor. We have also
confirmed experimentally that the Windows driver uses such information.

The _ONT data format was explained by a ST vendor contact. However,
strangely enough, the _ONT transformations must be applied after first
applying another mount matrix which we determined experimentally. ST
have not commented on why this is the case, but we imagine that perhaps
earlier devices (before _ONT was introduced) required this translation
and hence it became 'standard.'

Interpret the _ONT data and export the equivalent mount matrix to
userspace.

If no _ONT data is present, no mount matrix is exported.
