From bf0ff1cd21a34ced1b34a42f12de8ec1ae7cfd3b Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Tue, 13 Oct 2015 05:04:22 +0900 Subject: ARM: S3C64XX: Use PWM lookup table for smdk6410 Use a PWM lookup table to provide the PWM to the pwm-backlight device. The driver has a legacy code path that is required only because boards still use the legacy method of requesting PWMs by global ID. Replacing these usages allows that legacy fallback to be removed.
