Subject: [PATCH v15 03/11] ir-rx51: Use 64-bit division macro
Date: Tue, 26 May 2020 10:35:03 -0700 [thread overview]
Message-ID: <68f17a69e1c818ee80d6c29c852df35a126b47c6.1590514331.git.gurus@codeaurora.org> (raw)
In-Reply-To: <cover.1590514331.git.gurus@codeaurora.org>
In-Reply-To: <cover.1590514331.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.
