From a228d6e7ed8e3624b6c1497a550d8d0e2cac889f Mon Sep 17 00:00:00 2001 From: Pavel Pisa Date: Mon, 20 Aug 2007 21:39:41 +0100 Subject: [PATCH] [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 Acked-by: Sascha Hauer Signed-off-by: Russell King --- arch/arm/mach-imx/generic.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/mach-imx/generic.c b/arch/arm/mach-imx/generic.c index a58b678006df..c342595dc318 100644 --- a/arch/arm/mach-imx/generic.c +++ b/arch/arm/mach-imx/generic.c @@ -138,7 +138,7 @@ EXPORT_SYMBOL(imx_gpio_direction_input); int imx_gpio_direction_output(unsigned gpio, int value) { imx_gpio_set_value(gpio, value); - imx_gpio_mode(gpio| GPIO_OUT); + imx_gpio_mode(gpio | GPIO_OUT | GPIO_GIUS | GPIO_DR); return 0; } -- 2.30.2
