On OMAP the OCMC RAM is always clocked and doesn't need any special
clock enable. CM_L3_2_OCMC_RAM_CLKCTRL module mode field is read only.
Isn't it same on AMXX ?
On AM33xx, OCMC RAM is in PER domain and the corresponding CLKCLTR
module
mode fields are r/w. OCMC RAM needs to be disabled as part of the
DeepSleep0
entry to let PER domain transition.
After DeepSleep0, the ROM code is being given an address in OCMC RAM to
jump to. If OCMC RAM is disabled as part of suspend, this means that
OCMC RAM contents are maintained even though PER domain transitions?
If so, that needs to be more clearly documented.
Thats very good point. How does OCMC RAM retains the contents without
clock ?
Ignore the question. I figured out from other patch changelog the OCMC
RAM supports retention. Please have that clearly captured in
change log.
