Subject: [PATCH] m68knommu: configurable frequency selection header
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=31f4fde38c5027ca05941db4a05c163d6314278e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] m68knommu: configurable frequency selection header

Remove list of fixed clock frequency options used for configuring master
clock, and make field an int. Much more flexible this way, no need to add
more options for every new used freqency.
