pinctrl: add a Cirrus ep93xx SoC pin controller Add a pin control (only multiplexing) driver for ep93xx SoC so we can fully convert ep93xx to device tree. This driver is capable of muxing ep9301/ep9302/ep9307/ep9312/ep9315 variants, this is chosen based on "compatible" in device tree.

pinctrl: add a Cirrus ep93xx SoC pin controller Add a pin control (only multiplexing) driver for ep93xx SoC so we can fully convert ep93xx to device tree. This driver is capable of muxing ep9301/ep9302/ep9307/ep9312/ep9315 variants, this is chosen based on "compatible" in device tree.

This driver is capable of muxing ep9301/ep9302/ep9307/ep9312/ep9315 variants, this is chosen based on "compatible" in device tree.
