Subject: [PATCH v15 01/11] drm/i915: Use 64-bit division macro
Date:   Tue, 26 May 2020 10:35:01 -0700
Message-Id: <4b56ba06f4f1e63cf50858d3e45c88057dc443e4.1590514331.git.gurus@codeaurora.org>

Precedence: bulk

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.
