[PATCH] ARM: dts: imx25-pinfunc: Fix gpio function name for pads GPIO_[A-F]

[Uwe Kleine-König]

Hello Shawn,

digging through my mailbox of unarchived mails I found this patch.

The reference manual (Rev. 2; 01/2011) doesn't give a name. The relevant
description for the GPIO_A pad reads:

	MUX Mode Select Field. Select 1 of 7 iomux modes to be used for pad: GPIO_A.

	000: Select mux mode: ALT0 mux port: GPIO[0] of instance: gpio1.
	...

So I'd say: GPIO_A is the pad name (only) and the function is better
named GPIO_1_0.

Best regards
Uwe
