[ARM] 4552/1: i.MX/MX1 GPIO output setup fix
The pins for GPIO should be provided as plain number build as (GPIO_PORTx + pin_number). But to setup the output GPIO_GIUS and GPIO_DR have to be specified in mode to route right value to the pin. This is a fix, it should go to 2.6.23 Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
