Subject: [PATCH v9 05/11] pwm: pwm-imx-tpm: Use 64-bit division macro
Date: Tue, 17 Mar 2020 13:05:20 -0700	[thread overview]
Message-ID: <8b4d40a1a5d927d09cca9fd0f1f3b99123a4c658.1584473399.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 DIV64_U64_ROUND_CLOSEST to
handle a 64-bit divisor.
