Subject: pwm: sifive: Use 64-bit division macro
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4cc23430a5361f29999545de34fc05fa7d8e513b;p=linux.git

pwm: sifive: Use 64-bit division macro

Since the PWM framework is switching struct pwm_args.period's datatype
to u64, prepare for this transition by using DIV64_U64_ROUND_CLOSEST to
handle a 64-bit divisor.
