[PATCH] clk: imx: imx8mm: fix audio pll setting

From: Peng Fan
Date: Sun Jul 14 2019 - 22:55:51 EST


From: Peng Fan <peng.fan@xxxxxxx>

The AUDIO PLL max support 650M, so the original clk settings violate
spec. This patch makes the output 786432000 -> 393216000,
and 722534400 -> 361267200 to aligned with NXP vendor kernel without any
impact on audio functionality and go within 650MHz PLL limit.
