regulator: fixed: obey startup delay

2016-09-06T17:18:21+00:00

When enabling a fixed regulator, it may take some time to rise to the
correct voltage.  If we do not delay here then subsequent operations
will fail.

power: regulator: act8846: fix reading values

2016-08-12T15:23:12+00:00

The voltage and control registers need to be looked up from the value in
driver_data.  Adjust the get_value and get_enable functions to match the
corresponding set_* functions.

dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()

2016-07-27T20:15:07+00:00

This new function is more convenient for callers, and handles pre-relocation
situations automatically.

dm: Use uclass_first_device_err() where it is useful

2016-03-14T21:34:50+00:00

Use this new function in places where it simplifies the code.

dm: power: Allow regulators to not implement all operations

2016-01-22T03:42:35+00:00

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.

dm: power: Tidy up debugging output and return values

2016-01-22T03:42:35+00:00

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.

dm: power: Allow regulators to be omitted from SPL

2016-01-22T03:42:35+00:00

For some boards the pmic interface is useful but the regulator interface
(which comes with it) is too large. Allow them to be separated such that
SPL can decide which it needs.

power: Add support for RK808 regulators

2016-01-22T03:42:34+00:00

Add regulator support for the RK808 PMIC. It integrated 4 BUCKs and 8 LDOs
all of which are supported by this driver.

power: regulator: max77686: Don't use switch() on bools

2016-01-19T13:32:00+00:00

With gcc-5.3 we get a warning for using switch() on a bool type.
Rewrite these sections as if/else and update the one section that was
using 1/0 instead of true/false.

dm: regulator: add function device_get_supply_regulator()

2015-11-02T01:38:00+00:00

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.
