From 812e8b22ea55218449de310a666dd1ce16f924ed Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Mon, 17 Sep 2012 07:48:33 -0300 Subject: [PATCH] [media] sh-mobile-ceu-driver: support max width and height in DT Some CEU implementations have non-standard (larger) maximum supported width and height values. Add two OF properties to specify them.
