      ASoC: Intel: avs: Fixes and new boards support · 46234fbe
      Mark Brown authored 
      Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

Two fixes are leading the way - one addresses the incorrect DMA mask
assignment (typo) at driver probe. The other, fixes a potential buffer
overflow when copying data received from firmware to kernel buffer.
However unlikely, the fix should still be there.

Then a range of patches providing the support for:
- AML with rt286 (machine board)
- KBL-R for rt298 (codec)
- KBL-R with rt298 (machine board)
- APL/KBL with da7219 (machine board)
- Addition of all the missing SKL-based PCI ids to core.c

Of the remaining changes, only one stands out - special case is provided
for "unsupported" IPCs. The driver supports a range of platforms,
however, on some generations given IPC may not be supported. Such call
shall not be treated as "invalid" - those are two different scenarios.

Everything else in the patchset is mostly a readability improvement:
spelling fixes and log messages issues, code simplification.

      Create a new sound card to access MICFIL based on rpmsg channel · a2ddd19f

      Merge series from Chancel Liu <chancel.liu@nxp.com>:

At a previous time, we have successfully created a virtual sound card
based on rpmsg. The sound card works under this mechanism Cortex-A core
tells the Cortex-M core the format, rate, channel, .etc configuration
of the PCM parameters and Cortex-M controls real hardware devices such
as SAI and DMA. From the view of Linux side, the sound card is bound to
a rpmsg channel through which it can access SAI.

Here these patches are introduced to create a new virtual sound card to
access MICFIL based on a new created rpmsg channel. It's easy to create
a new rpmsg channel for MICFIL through rpmsg name service announcment.
Also the other ASoC components bound to this rpmsg MICFIL sound card
will be registered with these patches.

If other sound cards using different hardware devices needs to be
created over rpmsg in the future, these patches can be referred.

      ASoC: codecs: jz4725b: Various improvements and fixes · c39e299a
      Mark Brown authored 
      Merge series from Siarhei Volkau <lis8215@gmail.com>:

The patchset fixes:
 - Line In path stays powered off during capturing or
   bypass to mixer.
 - incorrectly represented dB values in alsamixer, et al.
 - incorrect represented Capture input selector in alsamixer
   in Playback tab.
 - wrong control selected as Capture Master

The patchset improves:
 - Exposes output stage (post mixer) gain control and makes it new
   Master playback gain, DAC gain was the previous master.
   However, no Master mute now.
 - Exposes all mixer inputs (both Mics, LineIn and DAC) with their
   gain controls.
 - Exposes microphones widgets: single/differential input, boost.

Known issues:
 - Bypass path enablement isn't applied immediately, for make
   things going bit clock needs to be triggered for a bit,
   e.g. by aplay dummy.wav
   It might be a hardware bug, since the bit clock isn't
   declared as required for codec operation.

Tested on:
 - Ritmix RZX-27 (jz4725b).
 - Ritmix RZX-50 (jz4755).

      ASoC: Use DIV_ROUND_UP() instead of open-coding it · 67ad4edf

      Merge series from Shang XiaoJing <shangxiaojing@huawei.com>:

Use DIV_ROUND_UP() instead of open-coding it, which intents and makes
it more clear what is going on for the casual reviewer.
