Merge tag 'asoc-v4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next 

ASoC: Updates for v4.21

Not much work on the core this time around but we've seen quite a bit of
driver work, including on the generic DT drivers.  There's also a large
part of the diff from a merge of the DaVinci and OMAP directories, along
with some active development there:

 - Preparatory work from Morimoto-san for merging the audio-graph and
   audio-graph-scu cards.
 - A merge of the TI OMAP and DaVinci directories, the OMAP product line
   has been merged into the DaVinci product line so there is now a lot
   of IP sharing which meant that the split directories just got in the
   way.  This has pulled in a few architecture changes as well.
 - A big cleanup of the Maxim MAX9867 driver from Ladislav Michl.
 - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
   RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
   controllers.

Once a robust fix has been developed, our preference is to release the

fix in a timely fashion, treating it no differently than any of the other

thousands of changes and fixes the Linux kernel project releases every

month.



However, at the request of the reporter, we will postpone releasing the

fix for up to 5 business days after the date of the report or after the

embargo has lifted; whichever comes first.  The only exception to that

rule is if the bug is publicly known, in which case the preference is to

release the fix as soon as it's available.

Once a robust fix has been developed, the release process starts.  Fixes

for publicly known bugs are released immediately.



Although our preference is to release fixes for publicly undisclosed bugs

as soon as they become available, this may be postponed at the request of

the reporter or an affected party for up to 7 calendar days from the start

of the release process, with an exceptional extension to 14 calendar days

if it is agreed that the criticality of the bug requires more time.  The

only valid reason for deferring the publication of a fix is to accommodate

the logistics of QA and large scale rollouts which require release

coordination.



Whilst embargoed information may be shared with trusted individuals in

order to develop a fix, such information will not be published alongside
