[PATCH 5.2 20/45] clk: imx: imx8mm: fix audio pll setting

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Peng Fan <peng.fan@xxxxxxx>

commit 053a4ffe298836bb973d2cba59f82fff60c7db5b upstream.

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.
