Subject: ARM: at91/dt: sama5d4: add rgb777 LCD line configuration
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=3c42ae3645a7fd2605453de9947629fb7b26c95f;p=deliverable%2Flinux.git

ARM: at91/dt: sama5d4: add rgb777 LCD line configuration

For the SAMA5D4 SoC, some LCD lines are in conflict with useful peripherals.
Remove these lines and the lowest significant bit of a 24 bit LCD. It gives
us a RGB 777 configuration.
