[C][SRU][PATCH 0/3] Fix the audio on some Chromebooks

[Po-Hsu Lin]

BugLink: https://bugs.launchpad.net/bugs/1811566

== Justification ==
Commit 648e921888ad96ea3dc922739e96716ad3225d7f (clk: x86: Stop marking clocks
as CLK_IS_CRITICAL) backported to Cosmic kernel fixed the bug that keeps unused
clocks on, but it is breaking the audio support on some Chromebooks (Swanky /
Clapper/ Gnawty) since we were not using the right clock in the
cht_bsw_max98090_ti machine driver.

== Fix ==
a182ecd (ASoC: intel: cht_bsw_max98090_ti: Add quirk for boards using pmc_plt_clk_0)
984bfb3 (ASoC: intel: cht_bsw_max98090_ti: Add pmc_plt_clk_0 quirk)
94ea56c (ASoC: intel: cht_bsw_max98090_ti: Add pmc_plt_clk_0 quirk)

These 3 patches can be cherry-picked to Cosmic.

== Test ==
Test kernel with these 3 patches could be found in:
http://people.canonical.com/~phlin/kernel/lp-1811566-chromebook-Gnawty/

Bug reporter stated that this kernel can fix the audio issue as expected.

== Regression potential ==
Low,
changes are limited in the cht_bsw_max98090_ti driver with a new DMI based
quirk table that contains these 3 Chromebook models and some logic to
determine the right clock to use.
