Subject: [PATCH v13 01/11] drm/i915: Use 64-bit division macro
Date: Tue, 21 Apr 2020 19:57:13 -0700	[thread overview]
Message-ID: <4a3acf8673c08308848fb7ae73d992b6feb758d3.1587523702.git.gurus@codeaurora.org> (raw)
In-Reply-To: <cover.1587523702.git.gurus@codeaurora.org>
In-Reply-To: <cover.1587523702.git.gurus@codeaurora.org>

Since the PWM framework is switching struct pwm_state.duty_cycle's
datatype to u64, prepare for this transition by using DIV_ROUND_UP_ULL
to handle a 64-bit dividend.
