Did you really mean to flip CTRL and CNTR here? If so, that's super
confusing and deserves a comment. AKA, I think the above should not
be:
+ .regs.cntr = PWM_CTRL,
+ .regs.ctrl = PWM_CNTR,
...but should be
+ .regs.cntr = PWM_CNTR,
+ .regs.ctrl = PWM_CTRL,
If you didn't mean to flip CTRL and CNTR here, then just get rid of
pwm_data_vop and refer to pwm_data_v2. In fact, I'd suggest that you
totally remove the "rockchip,vop-pwm" since there's nothing different
between "rockchip,rk3288-pwm" and "rockchip,vop-pwm".
Sorry,I think it's no problem. the "rockchip,rk3288-pwm" and
"rockchip,vop-pwm" are seperate PWM controllers.
They are just different registers address between CNTR and CTRL .
Have you validated Thierry's suggestion to allow you to access your
memory range?
Yes,we have solve it in lcdc driver.
