Initialize a dummy regulator to satisfy this requirement. Signed-off-by: Andrew Chew --- Changed the device name of the backlight regulator supply to "pwm-backlight", per Peter's comment. Changed the name of the regulator to "backlight-enable", per Thierry's suggestion. arch/arm/mach-omap2/board-4430sdp.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/arch/arm/mach-omap2/board-4430sdp.c b/arch/arm/mach-omap2/board-4430sdp.c index 35f3ad0..a01a39a 100644 --- a/arch/arm/mach-omap2/board-4430sdp.c +++ b/arch/arm/mach-omap2/board-4430sdp.c @@ -291,6 +291,10 @@ static struct platform_device sdp4430_leds_pwm = { }, }; +/* Dummy regulator for pwm-backlight driver */ +static struct regulator_consumer_supply backlight_supply = + REGULATOR_SUPPLY("enable", "pwm-backlight"); + static struct platform_pwm_backlight_data sdp4430_backlight_data = { .max_brightness = 127, .dft_brightness = 127, @@ -718,6 +722,8 @@ static void __init omap_4430sdp_init(void) omap4_i2c_init(); omap_sfh7741prox_init(); + regulator_register_always_on(-1, "backlight-enable", + &backlight_supply, 1, 0); platform_add_devices(sdp4430_devices, ARRAY_SIZE(sdp4430_devices)); omap_serial_init(); omap_sdrc_init(NULL, NULL);
