Subject: ARM: 6210/1: Do not rely on reset defaults of L2X0_AUX_CTRL
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4082cfa77680a70e407efdfb207c743107bd8fe4;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ARM: 6210/1: Do not rely on reset defaults of L2X0_AUX_CTRL

On i.MX35 the L2X0_AUX_CTRL register does not have sensible reset
default values. Allow them to be overwritten with the aux_val/aux_mask
arguments passed to l2x0_init().
