From 5a8b572d832772722c3b3b7578e7fb968560fcf3 Mon Sep 17 00:00:00 2001
From: Archit Taneja <archit@ti.com>
Date: Thu, 12 May 2011 17:26:29 +0530
Subject: [PATCH] OMAP4: DSS2: DSI: Changes for DSI2 on OMAP4

Introduce DSI2 PLL clock sources needed by LCD2 channel and DSI2 Protocol
engine and DISPC Functional clock. Do the following:

- Modify dss_get_dsi_clk_source() and dss_select_dsi_clk_source() to take the
  dsi module number as an argument.
- Create debugfs files for dsi2, split the corresponding debugfs functions.
- Allow DPI to use these new clock sources.
