From: Alex Elder <redacted> Add a driver for the GPIO controller embedded in the Toshiba TC9563 PCIe switch (and the Qualcomm QPS615). The device implements 35 GPIOs using two register banks: three registers control the first 32 GPIOs (20 and 21 are reserved) and three more control GPIOs 32-36. GPIOs 22-24, 27-28, 31, and 34 are input-only. The driver is registered as an auxiliary device driver. The TC9563 power controller creates the auxiliary device and provides a regmap that gives access to the GPIO registers, so the gpio-regmap helpers are used to implement the GPIO chip.
