If anyone has any objections, please let me know. ------------------ From: Dmitry Eremin-Solenikov commit 9bc78f32c2e430aebf6def965b316aa95e37a20c upstream. Add regulator_has_full_constraints() call to poodle board file to let regulator core know that we do not have any additional regulators left. This lets it substitute unprovided regulators with dummy ones. This fixes the following warnings that can be seen on poodle if regulators are enabled: ads7846 spi1.0: unable to get regulator: -517 spi spi1.0: Driver ads7846 requests probe deferral wm8731 0-001b: Failed to get supply 'AVDD': -517 wm8731 0-001b: Failed to request supplies: -517 wm8731 0-001b: ASoC: failed to probe component -517 Signed-off-by: Dmitry Eremin-Solenikov Acked-by: Mark Brown Signed-off-by: Robert Jarzmik Signed-off-by: Luis Henriques --- arch/arm/mach-pxa/poodle.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm/mach-pxa/poodle.c b/arch/arm/mach-pxa/poodle.c index 131991629116..e81d216b05e4 100644 --- a/arch/arm/mach-pxa/poodle.c +++ b/arch/arm/mach-pxa/poodle.c @@ -25,6 +25,7 @@ #include #include #include +#include #include #include #include @@ -455,6 +456,7 @@ static void __init poodle_init(void) pxa_set_i2c_info(NULL); i2c_register_board_info(0, ARRAY_AND_SIZE(poodle_i2c_devices)); poodle_init_spi(); + regulator_has_full_constraints(); } static void __init fixup_poodle(struct tag *tags, char **cmdline)
