You seem to take the other direction here: you're removing > rockchip_pwm_ops_v1 and renaming rockchip_pwm_ops_v2 into > rockchip_pwm_ops. Yes, i really didn't understand exactly what you mean. Your mean is that remove the set_enable, get_state and other hooks, then use the pwm_ops instead of them, which has 3 different version, and implement the pwm_ops's functions like apply(), enable(), get_state() and others...?
