Subject: ARM: integrator: move CP CLCD display to DTS
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e3f617602103ef674aec417d52f0cff145fc0599;p=linux-beck.git

ARM: integrator: move CP CLCD display to DTS

The Integrator/CP CLCD VGA display can now be registered
fully from the device tree. Delete the board file code and
add the display definition to the DTS.
