[PATCH] ASoC: cs35l41: Add 12288000 clk freq to cs35l41_fs_mon clk config

[Jianhua Lu]

There are 8 cs35l41 speaker amplifier connected to TDM
in my Xiaomi Mi Pad 5 Pro tablet. In this case, it's necessary
to set 12288000 (48000 * 32 * 8) clk freq for it.

rate=48000, slot_width=32, slots=8.

This is a valid clocking configuration. 12.288 MHz is already available 
in cs35l41_pll_sysclk[] as well.
Values for fs1 and fs2 are not required because cs35l41_dai_set_sysclk() 
will use hardcoded values for freq > 6.144 MHz.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
