Pull more ACPI and power management updates from Rafael Wysocki:
"These are regression fixes (leds-gpio, ACPI backlight driver,
operating performance points library, ACPI device enumeration
messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device
PM), some cleanups in the operating performance points (OPP)
framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of
minor intel_pstate driver changes, a new MAINTAINERS entry for it and
an ACPI fan driver change needed for better support of thermal
management in user space.
Specifics:
- Fix a regression in leds-gpio introduced by a recent commit that
inadvertently changed the name of one of the properties used by the
driver (Fabio Estevam).
- Fix a regression in the ACPI backlight driver introduced by a
recent fix that missed one special case that had to be taken into
account (Aaron Lu).
- Drop the level of some new kernel messages from the ACPI core
introduced by a recent commit to KERN_DEBUG which they should have
used from the start and drop some other unuseful KERN_ERR messages
printed by ACPI (Rafael J Wysocki).
- Revert an incorrect commit modifying the cpupower tool (Prarit
Bhargava).
- Fix two regressions introduced by recent commits in the OPP library
and clean up some existing minor issues in that code (Viresh
Kumar).
- Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the
tree (or drop it where that can be done) in order to make it
possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf
Hansson, Ludovic Desroches).
There will be one more "CONFIG_PM_RUNTIME removal" batch after this
one, because some new uses of it have been introduced during the
current merge window, but that should be sufficient to finally get
rid of it.
- Make the ACPI EC driver more robust against race conditions related
to GPE handler installation failures (Lv Zheng).
- Prevent the ACPI device PM core code from attempting to disable
GPEs that it has not enabled which confuses ACPICA and makes it
report errors unnecessarily (Rafael J Wysocki).
- Add a "force" command line switch to the intel_pstate driver to
make it possible to override the blacklisting of some systems in
that driver if needed (Ethan Zhao).
- Improve intel_pstate code documentation and add a MAINTAINERS entry
for it (Kristen Carlson Accardi).
- Make the ACPI fan driver create cooling device interfaces witn
names that reflect the IDs of the ACPI device objects they are
associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").
That's necessary for user space thermal management tools to be able
to connect the fans with the parts of the system they are supposed
to be cooling properly. From Srinivas Pandruvada"

Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks
depending on CONFIG_PM_RUNTIME may now be changed to depend on
CONFIG_PM.

ASoC: Updates for v3.19
Lots and lots of changes this time around, the usual set of driver
updates and a huge bulk of cleanups from Lars-Peter. Probably the most
interesting thing for most users is the Intel driver updates which will
(with some more machine integration work) enable support for newer x86
laptops.
- Conversion of AC'97 drivers to use regmap, bringing us closer to the
removal of the ASoC level I/O code.
- Clean up a lot of old drivers that were open coding things that have
subsequently been implemented in the core.
- Some DAPM performance improvements.
- Removal of the now seldom used CODEC mutex.
- Lots of updates for the newer Intel SoC support, including support
for the DSP and some Cherrytrail and Braswell machine drivers.
- Support for Samsung boards using rt5631 as the CODEC.
- Removal of the obsolete AFEB9260 machine driver.
- Driver support for the TI TS3A227E headset driver used in some
Chrombeooks.

The cause of problem and solution are well explained by Lars-Peter:
"The driver creates the mapping by calling irq_of_parse_and_map(), so it also
has to dispose the mapping. But the easy way out is to simply use
platform_get_irq() instead of irq_of_parse_map(). In this case the mapping is
not managed by the device but by the of core, so the device has not to dispose
the mapping."
Tested on a imx6q-sabresd board.

ESAI may need to use fixed slot width to comply with external
CODEC. So this set_tdm_slot() call will allow the ESAI driver
to override its default dynamic slot width policy.

The driver previously used 32-bit fixed slot width as default.
In result, ESAI might use 32-bit length to capture 16-bit width
audio slot from CODEC side when ESAI is running as DAI slave.
So this patch just removes the default slot_width so as to use
dynamic slot width. If there comes a specific situation that
needs a fixed width, the machine driver shall set slot_width
via set_tdm_slot() so as to let the ESAI driver replace the
dynamic width policy with the fixed value.

Setting the ac97_control field on a CPU DAI tells the ASoC core that this
DAI in addition to audio data also transports control data to the CODEC.
This causes the core to suspend the DAI after the CODEC and resume it before
the CODEC so communication to the CODEC is still possible. This is not
necessarily something that is specific to AC'97 and can be used by other
buses with the same requirement. This patch renames the flag from
ac97_control to bus_control to make this explicit.
While we are at it also change the type from int to bool.
The following semantich patch was used for automatic conversion of the
drivers:
// <smpl>
@@
identifier drv;

struct snd_soc_dai_driver drv = {
- .ac97_control
+ .bus_control

The mpc5200_dma overwrites the private_data field of the CODEC's AC'97
device with the DMA drivers private data, but never actually reads it again.
Given that the private_data field is supposed to be owned by the AC'97
driver, overwriting it may cause undefined behavior. This patch removes the
code that overwrites the field from the driver.

The mpc5200_psc_ac97 driver puts a snd_ac97 device on the stack in the

the never uses the device again. It should be safe to remove it.

When cpu-dai is the DAI Master (CBM_CFx), it may need some configurations,
set_sysclk() call for eample, for cpu-dai side in the hw_params(), even if

=============================================================================
By looking at 2744 line, we can get that it's because regcache_rbtree_write()
would call kmalloc() with GFP flag if it couldn't find an existing block to
insert nodes while this kmalloc() call is inside a spin_lock_irq_save pair,
i.e. IRQs disabled.
Even though this may be a bug that should be fixed, I still try to send this
patch as a quick fix (work around) since it does no harm to assign default
values of every registers when using regcache.

The of_node_put() calls in imx_es8328_probe() may take uninitialized
pointers when reached though the early error path. This patch adds
the proper NULL initialization for fixing these.

The wm8962 driver uses the input subsystem, but it is selected by
SND_SOC_FSL_ASOC_CARD, which can be built with CONFIG_INPUT disabled,
resulting in this link error:
ERROR: "input_event" [sound/soc/codecs/snd-soc-wm8962.ko] undefined!
ERROR: "input_register_device" [sound/soc/codecs/snd-soc-wm8962.ko] undefined!
ERROR: "devm_input_allocate_device" [sound/soc/codecs/snd-soc-wm8962.ko] undefined!
Do not force the selection of the codecs by SND_SOC_FSL_ASOC_CARD to avoid
such problem.

There is no need to use 'i2s-slave' property, since master/slave configuration
are passed via machine layer.
This change does not break existing users because they do check for slave
mode inside sound/soc/fsl/mpc8610_hpcd.c/p1022_ds.c/p1022_rdk.c

code can raise a panic when the ssi_private->pdev is null

Proposal was to not use ssi_private->pdev->dev here but adding a new parameter
of *dev pointer to this _set_dai_fmt() -- passing pdev->dev in probe() and
cpu_dai->dev in fsl_ssi_set_dai_fmt().

Check if ipg clock is in clock-names property, then we can move the
ipg clock enable and disable operation to startup and shutdown, that
is only enable ipg clock when ssi is working and keep clock is disabled
when ssi is in idle.
But when the checking is failed, remain the clock control as before.

The 'big-endian-data' property is originally used to indicate whether the
LSB firstly or MSB firstly will be transmitted to the CODEC or received
from the CODEC, and there has nothing relation to the memory data.
Generally, if the audio data in big endian format, which will be using the
bytes reversion, Here this can only be used to bits reversion.
So using the 'lsb-first' instead of 'big-endian-data' can make the code
to be readable easier and more easy to understand what this property is
used to do.
This property used for configuring whether the LSB or the MSB is transmitted
first for the fifo data.

Build kernel with SND_SOC_FSL_ASOC_CARD=m && SND_SOC_FSL_{SSI,SAI,ESAI}=y
leads the following error:
sound/built-in.o: In function `fsl_sai_probe':

The config SND_SOC_FSL_ASOC_CARD is for IMX SOC, So move it under condition
of 'if SND_IMX_SOC'.

The imx-es8328 driver fails to build on PPC because it explicitly depends on
SND_SOC_IMX_PCM_FIQ, which itself doesn't build on PPC. Instead, rely on
the SND_SOC_FSL_SSI config option to pull in the necessary libraries.
While we're at it, remove SND_SOC_FSL_UTILS, which also is not needed.
