[PATCH AUTOSEL 6.6 15/47] ASoC: fsl_xcvr: refine the requested phy clock frequency
From: Shengjiu Wang shengjiu.wang@nxp.com
[ Upstream commit 347ecf29a68cc8958fbcbd26ef410d07fe9d82f4 ]
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
