From mboxrd@z Thu Jan 1 00:00:00 1970 From: Darren Etheridge Date: Fri, 23 Aug 2013 21:52:49 +0000 Subject: [PATCH 0/4] video: da8xx-fb: numerous bugfixes Message-Id: <1377294773-25678-1-git-send-email-detheridge@ti.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-fbdev@vger.kernel.org In developing a driver for an HDMI encoder to be attached to the LCD controller on TI AM335x SoC I ran across a number of bugs in the da8xx-fb.c fbdev driver. Two of them appear to have been in the driver for a while (02 and 04), one of them is a deficiency where some LCD controller version 2 features have not been utilized (03) and the last one was introduced in the last patch series that I submitted for this driver (01). These patches do not change the behavior of the AM335x EVM's platforms LCD panel even though the current values set by the driver are wrong. I guess LCD panels (at least the one used on AM335x EVM) must be fairly immune to bad timings coming from the LCD controller. However the HDMI encoder simply will not work without these fixes, and quite possibly other LCD panels could behave the same way. These patches apply on top of the patch series called: "video/da8xx-fb fbdev driver enhance to support TI am335x SoC" that was submitted by me.
