drivers: regulator: fixed: add u-boot, off-on-delay-us

2018-08-20T00:38:39Z

Add u-boot,off-on-delay-us for fixed regulator. Depends on board design, the gpio regulator sometimes connects with a big capacitance. When need to off, then on the regulator, if there is no enough delay, the voltage does not drop to 0, so introduce this property to handle such case.

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: obey startup delay

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.
