Subject: [PATCH 16/23] OMAPDSS: skip pclk check for WB mem2mem
Date: Wed, 09 Dec 2015 15:59:44 +0000 [thread overview]
Message-ID: <1449676791-26304-17-git-send-email-tomi.valkeinen@ti.com> (raw)
When doing mem-to-mem writeback, there's no pixelclock. However, the
code that calculates scaling factors check that there is a pixel clock.
We can just skip the check when doing mem-to-mem writeback.
