* Note that 814x seems to have HWSUP_SWSUP for many clockdomains
|
|
* while 816x does not. According to the TRM, 816x only has HWSUP
|
|
* for ALWON_L3_FAST. Also note that the TI tree clockdomains81xx.h
|
|
* seems to have the related ifdef the wrong way around claiming
|
|
* 816x supports HWSUP while 814x does not. For now, we only set
|
|
* HWSUP for ALWON_L3_FAST as that seems to be supported for both
|
|
* dm814x and dm816x.
