From e84dc1cc1503150e3bc37268a0b0f0bc0097622c Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen <tomi.valkeinen@ti.com> Date: Mon, 24 Sep 2012 09:34:52 +0300 Subject: [PATCH] OMAPDSS: DSI: fix tlpx_half reg field length tlpx_half bit field in DSI_DSIPHY_CFG1 is [20,16], not [22,16] as accessed in the code currently. Fix this. The bug should not have caused any problems on OMAP3/4, as the bits 21,22 are unused. They are used on OMAP5, though.
