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.

Applied, thanks.

I'm not completely happy with this patch going through your tree. It
does massive changes to arch/arm/mach-*mx*, so expect merge conflicts
here.

There are also massive changes going on in drivers/gpio.  The solution
here is to probably put these changes into a new dedicated branch
based on Linus' tree, we both agree not to rebase that branch, and
both of us merge the branch into our trees.
