From 8d7cf8370d5fb75a3265408dceb1d6173eebfafd Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Mon, 6 Jun 2011 09:37:58 -0600 Subject: gpio/mxs: Change gpio-mxs into an upstanding gpio driver 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.
