The pwm-backlight driver now takes a mandatory regulator that is gotten during driver probe. Initialize a dummy regulator to satisfy this requirement.
Signed-off-by: Andrew Chew <[email protected]> --- This patch, along with many more soon to follow, attempts to satisfy the new mandatory regulator that pwm-backlight will grab during probe. The only board in mach-omap2 to use the pwm-backlight appears to be the 4430sdp. I thought I'd start small and use this board as an example. I tested similar code in my Tegra board, so it should be okay. Of course, I don't have a 4430sdp to test with. arch/arm/mach-omap2/board-4430sdp.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/arch/arm/mach-omap2/board-4430sdp.c b/arch/arm/mach-omap2/board-4430sdp.c index 35f3ad0..62022c0 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", NULL); + static struct platform_pwm_backlight_data sdp4430_backlight_data = { .max_brightness = 127, .dft_brightness = 127, @@ -718,6 +722,7 @@ static void __init omap_4430sdp_init(void) omap4_i2c_init(); omap_sfh7741prox_init(); + regulator_register_always_on(-1, "bl-enable", &backlight_supply, 1, 0); platform_add_devices(sdp4430_devices, ARRAY_SIZE(sdp4430_devices)); omap_serial_init(); omap_sdrc_init(NULL, NULL); -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
