OMAP4: DSS2: HDMI: Split the current HDMI driver to move
Split the current HDMI driver to move the HDMI IP dependent ( PLL/PHY/Core configuration code) to a new IP file (ti_hdmi_4xxx_ip.c. This is to separate IP dependent OMAP agnostic code from OMAP specific DSS dependent code. Signed-off-by: Mythri P K <mythripk@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
