X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fa6d459d64a60db41c476c16063670ca4297e1d1;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mpc5121: remove obsolete cell-index property from PSC clock code

Don't use cell-index from device tree, obtain the PSC number
from PSCx register offset.
