As the input phy clock frequency will divided by 2 by default
on i.MX8MP with the implementation of clk-imx8mp-audiomix driver,
So the requested frequency need to be updated.

The relation of phy clock is:
    sai_pll_ref_sel
       sai_pll
          sai_pll_bypass
             sai_pll_out
                sai_pll_out_div2
                   earc_phy_cg

Thanks!

[1/1] ASoC: fsl_xcvr: refine the requested phy clock frequency
      commit: 347ecf29a68cc8958fbcbd26ef410d07fe9d82f4

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
