 * 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.
