Hello,
I reworked the series to improve the renesas-tpu PWM driver after
feedback I got from Geert. The changes are:
- Add Geert's tags for the first two patches
(I didn't add them for the other patches as I changed these enough to
not carry the tags forward.)
- Use tpu_pwm_disable instead chip->ops->disable (which is NULL now)
fixing a crash in v1.
- The calculation now uses a switch instead of ilog2.
Looking at the compiled code for ARM this is more effective and I
assume the same holds true for other platforms.
Thanks again to Geert for his valuable feedback and testing.
Best regards
Uwe
