microblaze: Add gpio.h Gpio support is not implemented yet. Adding it because of fdtdec. Signed-off-by: Michal Simek <monstr@monstr.eu>

#ifndef _ASM_MICROBLAZE_GPIO_H_
#define _ASM_MICROBLAZE_GPIO_H_
gpio: Add support for microblaze xilinx GPIO Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it. Add gpio driver and change Microblaze reset logic to be done via gpio subsystem. There are various configurations which Microblaze can have that's why gpio_alloc/gpio_alloc_dual(for dual channel) function has been introduced and gpio can be allocated dynamically. Adding several gpios IP is also possible and supported. For listing gpio configuration please use "gpio status" command This patch also remove one compilation warning: microblaze-generic.c: In function 'do_reset': microblaze-generic.c:38:47: warning: operation on '*1073741824u' may be undefined [-Wsequence-point] Signed-off-by: Michal Simek <michal.simek@xilinx.com>
