Subject: [PATCH] OMAP: ZOOM2: Change GPIO to enable LCD NEC NL8048HL11-01B on OMAP34x-II MDP
Date: Tue, 23 Nov 2010 19:00:02 -0600 [thread overview]
Message-ID: <1290560402-2507-1-git-send-email-omar.ramirez@ti.com> (raw)
From: Yanick Saugy <yanick.saugy@heig-vd.ch>
The PIN which controls LCD's reset signal (VGA_nRESET/h_GPIO_96) was not
configured as a GPIO. We had to modify the OMAP MUX, and select this PIN
(CAM_XCLKA) as an output GPIO (OMAP_MUX_MODE4). (kernel 2.6.35)
Be aware of changing this PIN will probably disable the camera, because
it was previously configured as a camera clock.

I'm not sure if this patch was forgotten, hence resending. Without
it, a blanks screen is seen on zoom2 board.
