Handle this case conditionally. Without this fix, Beagle XM 4 port EHCI will not function and no networking will be available [nm@ti.com: split up, added descriptive changelogs] Signed-off-by: Nishanth Menon Signed-off-by: Koen Kooi Signed-off-by: Tony Lindgren --- diff --git a/arch/arm/mach-omap2/board-omap3beagle.c b/arch/arm/mach-omap2/board-omap3beagle.c index 6c127605942f..af1166bd1c86 100644 --- a/arch/arm/mach-omap2/board-omap3beagle.c +++ b/arch/arm/mach-omap2/board-omap3beagle.c @@ -297,9 +297,15 @@ static int beagle_twl_gpio_setup(struct device *dev, gpio_request(gpio + 1, "EHCI_nOC"); gpio_direction_input(gpio + 1); - /* TWL4030_GPIO_MAX + 0 == ledA, EHCI nEN_USB_PWR (out, active low) */ + /* + * TWL4030_GPIO_MAX + 0 == ledA, EHCI nEN_USB_PWR (out, XM active + * high / others active low) + */ gpio_request(gpio + TWL4030_GPIO_MAX, "nEN_USB_PWR"); - gpio_direction_output(gpio + TWL4030_GPIO_MAX, 0); + if (omap3_beagle_get_rev() == OMAP3BEAGLE_BOARD_XM) + gpio_direction_output(gpio + TWL4030_GPIO_MAX, 1); + else + gpio_direction_output(gpio + TWL4030_GPIO_MAX, 0); /* TWL4030_GPIO_MAX + 1 == ledB, PMU_STAT (out, active low LED) */ gpio_leds[2].gpio = gpio + TWL4030_GPIO_MAX + 1;
