Clock source names vary across OMAP2/3 and OMAP4, the clock source enum names have been made generic in the driver, but for purposes of debugging and dumping clock sources, it is better to preserve the actual TRM name of the clock. Introduce a dss feature function 'dss_feat_get_clk_source_name()' which returns a string with the TRM clock name for the current OMAP in use. The OMAP specific name is printed along the generic name within brackets. Signed-off-by: Archit Taneja <archit@ti.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
