From mboxrd@z Thu Jan 1 00:00:00 1970 From: Tomi Valkeinen Date: Mon, 24 Sep 2012 13:58:36 +0000 Subject: [PATCH 6/9] OMAPDSS: DSI: Add FEAT_DSI_PLL_REFSEL Message-Id: <1348495119-8262-7-git-send-email-tomi.valkeinen@ti.com> List-Id: References: <1348495119-8262-1-git-send-email-tomi.valkeinen@ti.com> In-Reply-To: <1348495119-8262-1-git-send-email-tomi.valkeinen@ti.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: archit@ti.com, linux-omap@vger.kernel.org, linux-fbdev@vger.kernel.org Cc: Tomi Valkeinen Add FEAT_DSI_PLL_REFSEL. OMAP5's DSI PLL needs configuration to select the reference clock to be used. We always use SYSCLK.
