Hi, currently it is not possible to have a gpio enabled regulator that uses gpio 0. 0 is a valid gpio identifier so it has to be supported.
This series tries to fix this issue by adding a regulator_config field 'ena_gpio_valid' which should be true if ena_gpio is a valid gpio identifier. Otherwise ena_gpio is ignored. Patch 1 introduces 'ena_gpio_valid'. Patch 2 updates all drivers that set ena_gpio. Patch 3 changes the regulator core check for ena_gpio. Patch 4 and 5 are minor changes to regulator drivers unrelated to the gpio-0 issue. Best regards, Markus Markus Pargmann (5): regulator: Add ena_gpio_valid config regulator: Set ena_gpio_valid in regulator drivers regulator: Fix ena_gpio check regulator: Use gpio_is_valid regulator: Remove unnecessary ena_gpio initializations drivers/regulator/arizona-ldo1.c | 1 + drivers/regulator/core.c | 2 +- drivers/regulator/da9055-regulator.c | 1 + drivers/regulator/fixed.c | 4 +++- drivers/regulator/gpio-regulator.c | 4 +++- drivers/regulator/lp8788-ldo.c | 2 ++ drivers/regulator/max8952.c | 1 + drivers/regulator/pfuze100-regulator.c | 1 - drivers/regulator/s2mps11.c | 1 + drivers/regulator/s5m8767.c | 3 +-- drivers/regulator/tps65090-regulator.c | 1 + drivers/regulator/wm8994-regulator.c | 3 ++- include/linux/regulator/driver.h | 3 +++ 13 files changed, 20 insertions(+), 7 deletions(-) -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
