Subject: HACK: handle big reset control
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6dcfda3c0f4a838b93bfbe605a5e2a09a2ca882c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

HACK: handle big reset control

In prior chips, only big cluster supports CPD(Cluster Power Down),
therefore, big_reset_control() is called in cluster_enable/disable
function. It should be changed to consider cluster.
