From bfcb311744cf4a6d99602b022daabfc107bb35ca Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 5 Oct 2015 10:49:50 +0200 Subject: [PATCH] ARM: pxa: palmtc: Use PWM lookup table 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.
