From c7dcccaec2f7e99f95ad4b7c20f4f9086c6982be Mon Sep 17 00:00:00 2001 From: Guru Das Srinagesh Date: Tue, 2 Jun 2020 15:31:13 -0700 Subject: pwm: sun4i: Use nsecs_to_jiffies to avoid a division Since the PWM framework is switching struct pwm_state.period's datatype to u64, prepare for this transition by using nsecs_to_jiffies() which does away with the need for a division operation.
