From: Mike Rapoport Date: Wed, 10 Feb 2016 16:34:04 +0000 (+0200) Subject: staging: sm750fb: share common bits in display control registers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=85e4db5347a96560928d2995a2cd05f10b856d5e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git staging: sm750fb: share common bits in display control registers The display control registers for primary and secondary display share some of the bits and those bits can be defined in a single place and then used for manipulations of the relevant registers.
