| Subject: clk: imx: imx8mm: fix audio pll setting |
| |
| From: Peng Fan <peng.fan@nxp.com> |
| |
| 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. |
