Subject: [PATCH v8 05/12] pwm: clps711x: Use 64-bit division macro
Date: Tue, 10 Mar 2020 18:41:14 -0700 [thread overview]
Message-ID: <150969930ee5cfa038b6f20b4ca2291a81097c2b.1583889178.git.gurus@codeaurora.org> (raw)
In-Reply-To: <cover.1583889178.git.gurus@codeaurora.org>
In-Reply-To: <cover.1583889178.git.gurus@codeaurora.org>
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.
