From 0b8185733966c1863b6b90ca2697327118ce5032 Mon Sep 17 00:00:00 2001 From: "Kim, Milo" Date: Mon, 29 Apr 2013 16:18:03 -0700 Subject: backlight: lp855x: move backlight mode platform data The brightness of LP855x devices is controlled by I2C register or PWM input . This mode was selected through the platform data, but it can be chosen by the driver internally without platform data configuration. How to decide the control mode: If the PWM period has specific value, the mode is PWM input. On the other hand, the mode is register-based. This mode selection is done on the _probe(). Move 'mode' from a header file to the driver private data structure, 'lp855 x'. And correlated code was replaced.
