OMAP4: DSS2: HDMI: Add DSS feature for CTS calculation
CTS and N parameters are used to regenerate the audio clock from the TMDS clock at the HDMI sink. In OMAP4430 ES1.0 version the calculation of the CTS parameter is done by the HDMI IP (hardware mode) while in others it must be done by the HDMI driver (software mode). A DSS feature is used to indicate the HDMI driver which mode is used. Signed-off-by: Ricardo Neri <ricardo.neri@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
