power: regulator: fixed: get_enable should return integer

2017-07-19T10:13:59Z

get_enable should be able to return error values. Hence change the return type to integer. Signed-off-by: Keerthy Reviewed-by: Simon Glass

dm: regulator: Update fixed regulator to support livetree.

2017-06-01T13:03:13Z

Update this driver to support a live device tree. Signed-off-by: Simon Glass

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14Z

At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function. Signed-off-by: Simon Glass

regulator: fixed: Add support to handle enable-active-high DT property

2016-12-27T13:22:57Z

Add support to handle enable-active-high DT property. This property is used to drive the gpio controlling fixed regulator as active high when claiming gpio line. Signed-off-by: Vignesh R Acked-by: Simon Glass

regulator: fixed: honour optionality of enable gpio

2016-10-10T17:44:37Z

According to the binding documentation the fixed regulator enable GPIO is optional. However so far registration thereof failed if no enable GPIO was specified. Fix this by making it entirely optional whether an enable GPIO is used. Signed-off-by: Marcel Ziswiler Acked-by: Stephen Warren Signed-off-by: Tom Warren

regulator: fixed: obey startup delay

2016-09-06T17:18:21Z

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. Signed-off-by: John Keeping Reviewed-by: Tom Rini Reviewed-by: Simon Glass

dm: regulator: add fixed voltage regulator driver

2015-05-15T00:49:38Z

This driver implements regulator operations for fixed Voltage/Current value regulators. beside the standard regulator constraints, which are put into the uclass platform data, a typical fixed regulator node provides few additional properties like: - gpio - gpio-open-drain - enable-active-high - startup-delay-us The only 'gpio' is used by this driver and is kept in structure of type 'fixed_regulator_platdata', as a device platform data (dev->platdata). The driver implements: - get_value - get_current - get_enable - set_enable The regulator calls and commands can be used for fixed-regulator devices, and the proper error will be returned for prohibited.
