From 2c15513010493435c78f83202940ac3be11de2c3 Mon Sep 17 00:00:00 2001 From: Tom Rix Date: Sun, 28 Jun 2009 12:52:30 -0500 Subject: OMAP3 Move twl4030 power and led functions Because twl4030 now has its own device files, move exiting omap3 power_init_r to a new location. power_init_r is the only function in board/omap3/common. It initializes the twl4030 power for the board and enables the led. The power part of the the function is moved to twl4030_power_init in drivers/power/twl4030.c The power compilation is conditional on the existing config variable CONFIG_TWL4030_POWER. The led part is moved to twl4030_led_init in the new file drivers/misc/twl4030_led.c The led compilation is conditional on the new config variable CONFIG_TWL4030_LED The directory board/omap3/common was removed because power_init_r was the only function in it.
