The OMAP Display Subsystem has multiple clock sources available for its
modules. One of these sources has to be selected through a global control
register called DSS_CTRL.
For example, on OMAP4, the Display Controller Module's (DISPC) functional
clock can be derived from:
a) output of DPLL_PER's M5 divisor
b) output of DSI1 PLL's M4 divisor
c) output of DSI2 PLL's M4 divisor
d) output of HDMI PLL
There is, hence, an enum called 'dss_clk_source' which is used throughout
DSS2, to select clock sources for various DSS sub modules. These clock
source names are currently specific to OMAP2/3 TRM clock names.
All enum members, variables, functions which are based on these clock
source names have been made generic such that they can be used for future
OMAPs as well.
Archit Taneja (3):
OMAP2PLUS: DSS2: Make members of dss_clk_source generic
OMAP2PLUS: DSS2: Use dss features to get clock source names of
current OMAP
OMAP2PLUS: DSS2: DSI: Generalize DSI PLL Clock Naming
