So do we already have some way to deny autoidle for a clock from ti-sysc.c driver without pdata callbacks? Suman pointed out few days ago that for a reset driver to work we must do clkdm_deny_idle() and clkdm_allow_idle() as the hwmod code does. I gues that really just boils down to doing clk deny idle and allow idle on the clockdomain clkctrl clock? Regards, Tony
