From a0601c8944dc08c2d349c24bd9c0b09c406229fc Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Thu, 30 Oct 2008 11:05:00 +0000 Subject: [PATCH] leds: da903x: (da9030 only) led brightness reversed. The brightness control register calculation (for the pwm) is effectively the reverse of what would be expected. 1 is maximum brightness, 255 minimum. This patch inverts this.
