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 .
OK, I looked up in the TRM. Right, the CNTR and CTRL are flipped on
the vop. So I think that the only change you need is to add:
#define PWM_VOP_CTRL 0x00
#define PWM_VOP_CNTR 0x0c
...then use these new #defines for the vop structure.
As you have the code written right now it's very confusing. The new
#defines will fix this.
yeah, I think they can be used in the same context.
I will fix it in patch v5 if it is really need.
I think you should fix this, but if Thierry doesn't think so then it's
really his decision.
I remember In patch v2 [1],Thierry suggests me to fix it so if I have no to
get wrong.
[1]: https://lkml.org/lkml/2014/7/21/113
I think Thierry might not have realized that they were flipped...

Maybe you are right.
I will sent patch v5 fix the about tomorrow if it has no other problems.
