Subject: [PATCH v12 05/11] pwm: pwm-imx-tpm: Use 64-bit division macro
Date: Wed,  8 Apr 2020 23:52:34 -0700	[thread overview]
Message-ID: <49c4849ed363ffbbf0d89005ab1e77dd5458e862.1586414867.git.gurus@codeaurora.org> (raw)
In-Reply-To: <cover.1586414867.git.gurus@codeaurora.org>
In-Reply-To: <cover.1586414867.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.
