From 1689dcd433aaa0d32dec3fdb4bd166a0d38f4bbf Mon Sep 17 00:00:00 2001 From: Guru Das Srinagesh Date: Tue, 2 Jun 2020 15:31:11 -0700 Subject: [PATCH] pwm: imx27: Use 64-bit division macro Since the PWM framework is switching struct pwm_state.period's datatype to u64, prepare for this transition by using DIV_ROUND_UP_ULL to handle a 64-bit dividend.
