The Clapper model Chromebook uses pmc_plt_clk_0 instead of pmc_plt_clk_3
for the mclk, just like the Swanky model.
This commit adds a DMI based quirk for this.
This fixing audio no longer working on these devices after
commit 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL")
that commit fixes us unnecessary keeping unused clocks on, but in case of
the Clapper that was breaking audio support since we were not using the
right clock in the cht_bsw_max98090_ti machine driver.

Intel Merrifield has a reduced size of FIFO used in iDMA 32-bit controller,
i.e. 512 bytes instead of 1024.
Fix this by partitioning it as 64 bytes per channel.
Note, in the future we might switch to 'fifo-size' property instead of
hard coded value.

Hello,
We ran automated tests on a recent commit from this kernel tree:
Kernel repo: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git
Commit: 987a6da5152c Linux 4.19.7-rc1
The results of these automated tests are provided below.
Overall result: PASSED
Patch merge: OK
Compile: OK
Kernel tests: OK
Please reply to this email if you have any questions about the tests that we
ran or if you have any suggestions on how to make future tests more effective.

______________________________________________________________________________
Compile testing
---------------
We compiled the kernel for 2 architectures:
aarch64:
make options: make INSTALL_MOD_STRIP=1 -j56 targz-pkg
configuration: https://artifacts.cki-project.org/builds/aarch64/987a6da5152c29e37cc11de9a2…
x86_64:
make options: make INSTALL_MOD_STRIP=1 -j56 targz-pkg
configuration: https://artifacts.cki-project.org/builds/x86_64/987a6da5152c29e37cc11de9a2d…
Hardware testing
----------------
We booted each kernel and ran the following tests:
arm64:
/distribution/kpkginstall (boot test)
LTP lite - release 20180515
xfstests: ext4
xfstests: xfs
/kernel/misc/amtu
x86_64:
/distribution/kpkginstall (boot test)
LTP lite - release 20180515
xfstests: ext4
xfstests: xfs
/kernel/misc/amtu
[BUG]
A completely valid btrfs will refuse to mount, with error message like:
BTRFS critical (device sdb2): corrupt leaf: root=2 block=239681536 slot=172 \
bg_start=12018974720 bg_len=10888413184, invalid block group size, \
have 10888413184 expect (0, 10737418240]
Btrfs check returns no error, and all kernels used on this fs is later
than 2011, which should all have the 10G size limit commit.
[CAUSE]
For a 12 devices btrfs, we could allocate a chunk larger than 10G due to
stripe stripe bump up.
__btrfs_alloc_chunk()
|- max_stripe_size = 1G
|- max_chunk_size = 10G
|- data_stripe = 11
|- if (1G * 11 > 10G) {
stripe_size = 976128930;
stripe_size = round_up(976128930, SZ_16M) = 989855744
However the final stripe_size (989855744) * 11 = 10888413184, which is
still larger than 10G.
[FIX]
For the comprehensive check, we need to do the full check at chunk
read time, and rely on bg <-> chunk mapping to do the check.
We could just skip the length check for now.
