dm: power: Allow regulators to not implement all operations

2016-01-22T03:42:35Z

Some regulators will not implement any operations (e.g. fixed regulators). This is not an error, so allow the autoset process to continue when one of these regulators is found. Signed-off-by: Simon Glass

dm: power: Tidy up debugging output and return values

2016-01-22T03:42:35Z

The currect PMIC debugging is a little confusing. Adjust it so that it is clear whether the operation succeeded or failed. Also, avoid creating a new error return value when a perfectly good one is already available. Signed-off-by: Simon Glass

dm: regulator: add function device_get_supply_regulator()

2015-11-02T01:38:00Z

Some devices are supplied by configurable regulator's output. But there was no function for getting it. This commit adds function, that allows for getting the supply device by it's phandle. The returned regulator device can be used with regulator uclass's API. Signed-off-by: Przemyslaw Marczak Cc: Simon Glass Signed-off-by: Minkyu Kang

power: regulator use node name when no regulator-name

2015-08-12T08:02:59Z

If there is no property named 'regulator-name' for regulators, choose node name instead, but not directly return failure value. Signed-off-by: Peng Fan Cc: Przemyslaw Marczak Cc: Simon Glass

dm: power: Don't return an error when regulators are not autoset

2015-08-06T03:06:13Z

Not all regulators can be set up automatically. Adjust the code so that regulators_enable_boot_on() will return success when some are skipped. Only genuine errors are reported. Signed-off-by: Simon Glass Acked-by: Przemyslaw Marczak

dm: power: Use debug() for errors in regulator uclass

2015-07-21T23:39:26Z

To reduce unnecessary code size in an uncommon code path, use debug() where possible(). The driver returns an error which indicates failure. Signed-off-by: Simon Glass Tested-by: Przemyslaw Marczak Acked-by: Przemyslaw Marczak

dm: power: Add a function to set up all regulators

2015-07-21T23:39:26Z

The device tree provides information about which regulators should be on at boot, or always on. Use this to set them up automatically. Signed-off-by: Simon Glass Tested-by: Przemyslaw Marczak Acked-by: Przemyslaw Marczak

dm: pmic: Split output from function

2015-07-21T23:39:26Z

The regulator_autoset() function mixes printf() output and PMIC adjustment code. It provides a boolean to control the output. It is better to avoid missing logic and output, and this permits a smaller SPL code size. So split the output into a separate function. Also rename the function to have a by_name() suffix, since we would like to be able to pass a device when we know it, and thus avoid the name search.

dm: power: Add regulator flags to centralise auto-set logic

2015-07-21T23:39:26Z

Decide when the regulator is set up whether we want to auto-set the voltage or current. This avoids the complex logic spilling into the processing code. Signed-off-by: Simon Glass Tested-by: Przemyslaw Marczak Acked-by: Przemyslaw Marczak

dm: regulator: uclass driver code cleanup

2015-05-15T01:58:34Z

This cleanup includes: - remove of the preprocessor macros which pointed to long name functions - update of the names of some regulator uclass driver functions - cleanup of the function regulator_autoset() - reword of some comments of regulator uclass header file - regulator_get_by_platname: check error for uclass_find_* function calls - add function: regulator_name_is_unique - regulator post_bind(): check regulator name uniqueness - fix mistakes in: regulator/Kconfig - regulator.h: update comments - odroid u3: cleanup the regulator calls Signed-off-by: Przemyslaw Marczak Acked-by: Simon Glass Tested on sandbox: Tested-by: Simon Glass
