2021-07-14gpio: Add driver for Nomadik GPIOStephan Gerhold
Nomadik GPIO is a fairly simple GPIO module used in the ST-Ericsson Ux500 SoCs (and some older Nomadik SoCs). It uses registers where each GPIO is represented as a single bit, plus "set" and "clear" registers that allow updating the state without having to read the existing state. The driver implements support for it for use together with DM_GPIO and the existing ste-dbx5x0.dtsi device tree.
