From 35c1682cc069fc1f677012d3170757135e246b39 Mon Sep 17 00:00:00 2001 From: Grazvydas Ignotas Date: Fri, 23 Mar 2012 15:02:02 -0700 Subject: backlight: add support for Pandora backlight Add support for pandora (openpandora.org) backlight. It might look like all this could be done using pwm_bl.c instead, but there is a need of special programming sequence when turning on the LED driver chip or else it will misbehave. Doing this using pwm_bl.c would require to use some register programming and pwm functions from platform code, and ARM maintainers are allergic to driver-like code in /arch/arm nowadays. The PMIC PWM driver is currently missing too, so pwm_bl.c can't be used anyway.
