[Linux-stm32] [PATCH v1 0/2] pwm: stm32: A rounding fix and a cleanup

[Uwe Kleine-König]

Hello,

I extended pwmtestperf (part of libpwm[1]) to allow testing inversed
polarity wave forms. I'm not sure if I should like it or not, but this
immediately showed a rounding issue in the stm32 pwm driver. This is
fixed in the first commit.

The 2nd commit is just a cleanup that I have on my todo list for a
while. This required the addition of mul_u64_u64_div_u64_roundup() which
exists since v6.19-rc1~70^2~90.

I intend to send the fix to Linus before 7.1, but will give it a bit of
time in next before. The cleanup will wait until the next merge window.

Best regards
Uwe
