Hi everyone, This is v2 of the simplefb regulator support series. This series adds regulator claiming and enabling support for simplefb. Sometimes the simplefb display output path consits of external conversion chips and/or LCD drivers and backlights. These devices normally have GPIOs to turn them on and/or bring them out of reset, and regulators supplying power to them. While the kernel does not touch unclaimed GPIOs, the regulator core happily disables unused regulators. Thus we need simplefb to claim and enable the regulators used throughout the display pipeline. Instead of the unnamed "vinN-supply" properties, v2 supports any named regulator supplies under its device node. It will look through its properties, and claim any regulators by matching "*-supply", as Mark suggested. I've not done a generic helper in the regulator core yet, instead doing the regulator property handling in the simplefb code for now. Patch 1 adds the regulator properties to the DT binding. Patch 2 adds code to the simplefb driver to claim and enable regulators.
