To avoid branch merge conflict issue, it uses this load map, and this patch is 1) part. 1) add old/new style clock in platform 2) add new style clock method in driver 3) remove old tyle clock from platform Signed-off-by: Kuninori Morimoto Signed-off-by: Simon Horman --- diff --git a/arch/arm/boot/dts/r8a7790.dtsi b/arch/arm/boot/dts/r8a7790.dtsi index 71b1251f79c7..67a6d968cebb 100644 --- a/arch/arm/boot/dts/r8a7790.dtsi +++ b/arch/arm/boot/dts/r8a7790.dtsi @@ -313,6 +313,29 @@ clock-output-names = "extal"; }; + /* + * The external audio clocks are configured as 0 Hz fixed frequency clocks by + * default.
