The patch makes necessary changes on gpio-mxs as below to turn it into an upstanding gpio driver. * Clean up the gpio port definition stuff * Use readl/writel to replace mach-specific accessors __raw_readl/__raw_writel * Change mxs_gpio_init into mxs_gpio_probe function And it then migrates mach-mxs to the updated driver by adding corresponding platform devices.
