From: Rob Clark Date: Fri, 7 Nov 2014 18:06:54 +0000 (-0500) Subject: drm/msm/mdp4: don't care about fb in crtc X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=88ff1c2f3b5d4826bbe3b6ec3cf12a223dc0cb22;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/msm/mdp4: don't care about fb in crtc Since we are configuring things via MDP4_PIPE regs in the plane, it seems like setting the dimensions of the primary plane on the OVLP/DMA regs in crtc is unnecessary. This will make life easier when we want to do a nofb modeset.
