This series adds the ability for the pwm-regulator driver to have an enable-gpio property, a feature that is required for the VDD_GPU regulator of Jetson TX1. Before doing that though, it goes through a few required changes/improvements in the regulator framework. Patch 1 allows the regulator core to use both an enable GPIO and an enable callback for a given driver. This is required for our use-case since the PWM also needs to be enabled/disabled in pwm-regulator regardless of whether we are using an enable GPIO or not. Patches 2-4 factorize the enable GPIO DT parsing code. With fixed and GPIO regulators already using that feature, and PWM to do the same, it probably makes sense to only have one function doing this. The parsing function supports more properties than individual drivers require, but the DT binding is the authority on which properties are valid, not the implementation. Finally patches 5-6 add support for the enable GPIO in pwm-regulator and the corresponding DT binding. The binding is kept minimal (active-high and open-drain properties can be specified in the GPIO phandle) on purpose.
