We seem to have this layout WR_SOFT_RESET and WR_CONTROL in the TRM:

WR_SOFT_RESET
[0]     SOFT_RESET

WR_CONTROL
[3:2]   MMR_STDBYMODE   0 = force-idle, 1 = no-standby
[1:0]   MMR_IDLEMODE    0 = force-idle, 1 = no-idle

And so it seems to match what am33xx also has for am33xx_cpgmac_sysc
and am33xx TRM for 14.5.9 CONTROL register. So as far as I'm concerned:
