1fde5e83a1 ASoC: fsl_sai: Add driver suspend and resume to support MEGA Fast
For i.MX6 SoloX, there is a mode of the SoC to shutdown all power source of
modules during system suspend and resume procedure. Thus, SAI needs to save
all the values of registers before the system suspend and restore them after
the system resume.

abebcdfb64 sound updates for 4.3-rc1
There are little changes in core part, but lots of development are
 found in drivers, especially ASoC.  The diffstat shows regmap-
 related changes for a slight API additions / changes, and that's all.
 
 Looking at the code size statistics, the most significant addition
 is for Intel Skylake.  (Note that SKL support is still underway, the
 codec driver is missing.)  Also STI controller driver is a major
 addition as well as a few new codec drivers.
 
 In HD-audio side, there are fewer changes than the past.  The
 noticeable change is the support of ELD notification from i915
 graphics driver.  Thus this pull request carries a few changes in
 drm/i915.
 
 Other than that, USB-audio got a rewrite of runtime PM code.  It
 was initiated by lockdep warning, but resulted in a good cleanup in
 the end.
 
 Below are the highlights:
 
 Common:
 - Factoring out of AC'97 reset code from ASoC into the core helper
 - A few regmap API extensions (in case it's not pulled yet)
 
 ASoC:
 - New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
   RT298 and ST STI controllers
 - Machine drivers for Rockchip systems with MAX98090 and RT5645 and
   RT5650
 - Initial driver support for Intel Skylake devices
 - Lots of rsnd cleanup and enhancements
 - A few DAPM fixes and cleanups
 - A large number of cleanups in various drivers (conversion and
   standardized to regmap, component) mostly by Lars-Peter and Axel
 
 HD-audio:
 - Extended HD-audio core for Intel Skylake controller support
 - Quirks for Dell headsets, Alienware 15
 - Clean up of pin-based quirk tables for Realtek codecs
 - ELD notifier implenetation for Intel HDMI/DP
 
 USB-audio:
 - Refactor runtime PM code to make lockdep happier

ebac95a920 ASoC: fsl-ssi: Fix bitclock calculation for master mode
According to the datasheet 'pm', 'psr' and 'div2' should never be all 0.
Since commit 541b03ad6c ("ASoC: fsl_ssi: Fix the incorrect limitation of
the bit clock rate") this can happen, because for some bitclock rates
'pm' = 0 seems to be a valid choice but does not work due to hardware
restrictions. This results into a bad hardware behaviour (slow audio for
example). Feature tested on a i.MX25.

acde50a7bf ASoC: dmaengine_pcm: Make FLAG_NO_RESIDUE internal
Whether residue can be reported or not is not a property of the audio
controller but of the DMA controller. The FLAG_NO_RESIDUE was initially
added when the DMAengine framework had no support for describing the residue
reporting capabilities of the controller. Support for this was added quite a
while ago and recently the DMAengine framework started to complain if a
driver does not describe its capabilities and a lot of patches have been
merged that add support for this where it was missing. So it should be safe
to assume that driver on actively used platforms properly implement the DMA
capabilities API.

This patch makes the FLAG_NO_RESIDUE internal and no longer allows audio
controller drivers to manually set the flag. If a DMA driver against
expectations does not support reporting its capabilities for now the generic
DMAengine PCM driver will now emit a warning and simply assume that residue
reporting is not supported. In the future this might be changed to aborting
with an error.

02f51640fe ASoC: wm1133-ev1: Use card DAPM context to access widgets
The dapm field of the snd_soc_codec struct will eventually be removed
(replaced with the DAPM context from the component embedded inside the
CODEC). Replace its usage with the card's DAPM context. The idea is that
DAPM is hierarchical and with the card at the root it is possible to access
widgets from other contexts through the card context.

1ee89c519a The clk fixes for 4.0-rc4 comprise three themes. First are the usual
driver fixes for new regressions since v3.19. Second are fixes to the
 common clock divider type caused by recent changes to how we round clock
 rates. This affects many clock drivers that use this common code.
 Finally there are fixes for drivers that improperly compared struct clk
 pointers (drivers must not deref these pointers). While some of these
 drivers have done this for a long time, this did not cause a problem
 until we started generating unique struct clk pointers for every
 consumer. A new function, clk_is_match was introduced to get these
 drivers working again and they are fixed up to no longer deref the
 pointers themselves.

81efec8514 ASoC: fsl_spdif: fix struct clk pointer comparing
Since commit 035a61c314 ("clk: Make clk API return per-user struct clk
instances"), clk API users can no longer check if two struct clk
pointers are pointing to the same hardware clock, i.e. struct clk_hw, by
simply comparing two pointers.  That's because with the per-user clk
change, a brand new struct clk is created whenever clients try to look
up the clock by calling clk_get() or sister functions like clk_get_sys()
and of_clk_get().  This changes the original behavior where the struct
clk is only created for once when clock driver registers the clock to
CCF in the first place.  The net change here is before commit
035a61c314 the struct clk pointer is unique for given hardware
clock, while after the commit the pointers returned by clk lookup calls
become different for the same hardware clock.

That said, the struct clk pointer comparing in the code doesn't work any
more.  Call helper function clk_is_match() instead to fix the problem.

6c8ca30eec ASoC: fsl_ssi: Don't try to round-up for PM divisor calculation
According to i.MX6 Series Reference Manual, the formula to calculate
the sys clock is

sysclk rate = bclk rate * (div2 + 1) * (7 * psr + 1) * (pm + 1) * 2

Commit aafa85e71a ("ASoC: fsl_ssi: Add DAI master mode support for
SSI on i.MX series") added the divisor calculation which relies on
the clk_round_rate(). However, at that time, clk_round_rate() didn't
provide closest clock rates for some cases because it might not use
a correct rounding policy. So using the original formula (pm + 1) for
PM divisor was not able to give us a desired clock rate. And then we
used (pm + 2) to do the trick.

However, the clk-divider driver has been refined a lot since commit
b11d282dbe ("clk: divider: fix rate calculation for fractional rates")
Now using (pm + 2) trick would result an incorrect clock rate.

So this patch fixes the problem by removing the useless trick.
