powerpc: mpc85xx: Add dummy gpio.h to enable CONFIG_OF_CONTROL If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled. It includes <asm/gpio.h> and then <asm/gpio.h> includes <asm/arch/gpio.h>. As a result, all the SoCs that enable CONFIG_OF_CONTROL must have <asm/arch/gpio.h>. The right fix would be to split the lib/fdtdec.c to remove dependency on GPIO. This commit adds a dummy <asm/arch/gpio.h> to support OF_CONTROL for mpc85xx platform. A file mpc85xx_gpio.h exists in arch/powerpc/include/asm. The defintions in that file conflict with the ones in asm-generic/gpio.h. Hence a dummy header file has been added. This will be removed after FDT-GPIO stuff is fixed correctly.

dm: gpio: Add driver for MPC85XX GPIO controller This patch adds a driver for the built-in GPIO controller of the MPC85XX SoC (probably supporting other PowerQUICC III SoCs as well). Each GPIO bank is identified by its own entry in the device tree, i.e. gpio-controller@fc00 { #gpio-cells = <2>; compatible = "fsl,pq3-gpio"; reg = <0xfc00 0x100> } By default, each bank is assumed to have 32 GPIOs, but the ngpios setting is honored, so the number of GPIOs for each bank in configurable to match the actual GPIO count of the SoC (e.g. the 32/32/23 banks of the P1022 SoC). The usual functions of GPIO drivers (setting input/output mode and output value setting) are supported. The driver has been tested on MPC85XX, but it is likely that other PowerQUICC III devices will work as well.
