Expose the newly created init_data to the driver's parse callback so that it can futher enhance it with e.g. constraints of the regulator.
Signed-off-by: Bjorn Andersson <[email protected]> --- This is needed because calling regulator_register() with a of_node and of_match will overwrite the passed config->init_data. An alternative way would be to merge the parsed init_data with the driver provided one. drivers/regulator/max77686.c | 3 ++- drivers/regulator/of_regulator.c | 2 +- include/linux/regulator/driver.h | 3 ++- 3 files changed, 5 insertions(+), 3 deletions(-) diff --git a/drivers/regulator/max77686.c b/drivers/regulator/max77686.c index 15fb141..87cbef2 100644 --- a/drivers/regulator/max77686.c +++ b/drivers/regulator/max77686.c @@ -259,7 +259,8 @@ static int max77686_set_ramp_delay(struct regulator_dev *rdev, int ramp_delay) static int max77686_of_parse_cb(struct device_node *np, const struct regulator_desc *desc, - struct regulator_config *config) + struct regulator_config *config, + struct regulator_init_data *init_data) { struct max77686_data *max77686 = config->driver_data; diff --git a/drivers/regulator/of_regulator.c b/drivers/regulator/of_regulator.c index 24e812c..f65934f 100644 --- a/drivers/regulator/of_regulator.c +++ b/drivers/regulator/of_regulator.c @@ -309,7 +309,7 @@ struct regulator_init_data *regulator_of_get_init_data(struct device *dev, } if (desc->of_parse_cb) { - if (desc->of_parse_cb(child, desc, config)) { + if (desc->of_parse_cb(child, desc, config, init_data)) { dev_err(dev, "driver callback failed to parse DT for regulator %s\n", child->name); diff --git a/include/linux/regulator/driver.h b/include/linux/regulator/driver.h index 8a0165f..0f86a182 100644 --- a/include/linux/regulator/driver.h +++ b/include/linux/regulator/driver.h @@ -266,7 +266,8 @@ struct regulator_desc { const char *regulators_node; int (*of_parse_cb)(struct device_node *, const struct regulator_desc *, - struct regulator_config *); + struct regulator_config *, + struct regulator_init_data *); int id; bool continuous_voltage_range; unsigned n_voltages; -- 1.8.2.2 -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
