From e8ef96cb078abe1cc9e9a75ca85b7dea8ddfda1b Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 25 Jan 2007 16:24:01 -0800 Subject: [PATCH] ARM: OMAP: osk+mistral backlight, power, board specific Mistral-specific: - Add PWL-driven LCD backlight device - Apply power to the board even when the LCD isn't configured; things like EEPROM, temperature sensor, and wakeup switch depend on it.
