Hi,
current state is that pmu/ldo regulators work, but not the SWITCH ones.
these are read by linux using the supply of the regulator itself
} else if (rdev->supply) {
ret = regulator_get_voltage_rdev(rdev->supply->rdev);
tried to port this to barebox, but regulator-struct there does not have the supply member
} else if (rdev->supply) {
ret = regulator_get_voltage(rdev->supply);
so i added it here:
+++ b/include/regulator.h
@@ -86,6 +86,7 @@ struct regulator_dev {
struct regmap *regmap;
bool boot_on;
bool always_on;
+ struct regulator *supply;
/* the device this regulator device belongs to */
struct device_d *dev;
but now this needs to be set somwhere...linux set this in
set_supply(struct regulator_dev *rdev,
struct regulator_dev *supply_rdev)
which is called in regulator_resolve_supply (called by _regulator_get).
regards Frank
