Subject: [PATCH v9 03/11] ir-rx51: Use 64-bit division macro
Date: Tue, 17 Mar 2020 13:05:18 -0700 [thread overview]
Message-ID: <f57ccf7a30d2af5111f979947100ec57c8fc5979.1584473399.git.gurus@codeaurora.org> (raw)
In-Reply-To: <cover.1584473399.git.gurus@codeaurora.org>
In-Reply-To: <cover.1584473399.git.gurus@codeaurora.org>
Since the PWM framework is switching struct pwm_state.period's datatype
to u64, prepare for this transition by using DIV_ROUND_CLOSEST_ULL to
handle a 64-bit dividend.
