b78d8e59a6
The patch makes necessary changes on gpio-mxc as below to turn it into an upstanding gpio driver. * Add a list to save all mx2 ports references, so that mx2_gpio_irq_handler can walk through all interrupt status registers * Use readl/writel to replace mach-specific accessors __raw_readl/__raw_writel * Change mxc_gpio_init into mxc_gpio_probe function * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to be public at all, and also make some other cleanup on plat-mxc/include/mach/gpio.h at the same time And the patch then migrates mach-imx and mach-mx5 to the updated driver by adding corresponding platform devices.
