Subject: pwm: imx-tpm: Use 64-bit division macro
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fcdea6b2a3f6508618e39e061073a18c55993a1b;p=linux.git

pwm: imx-tpm: Use 64-bit division macro

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