From 7f1961018cb494c029fcbb446e6562064735ec5e Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 20 Oct 2014 19:48:39 -0600 Subject: dm: exynos: Make sure that GPIOs are requested With driver model GPIOs must be requested before use. Make sure this is done correctly. (Note that the soft SPI part of universal is omitted, since this driver is about to be replaced with a driver-model-aware version) Signed-off-by: Simon Glass --- board/samsung/smdk5420/smdk5420.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'board/samsung/smdk5420') diff --git a/board/samsung/smdk5420/smdk5420.c b/board/samsung/smdk5420/smdk5420.c index 47998abeaf..a691222b8b 100644 --- a/board/samsung/smdk5420/smdk5420.c +++ b/board/samsung/smdk5420/smdk5420.c @@ -74,9 +74,12 @@ void exynos_lcd_power_on(void) mdelay(5); /* TODO(ajaykumar.rs@samsung.com): Use device tree */ + gpio_request(EXYNOS5420_GPIO_X35, "edp_slp#"); gpio_direction_output(EXYNOS5420_GPIO_X35, 1); /* EDP_SLP# */ mdelay(10); + gpio_request(EXYNOS5420_GPIO_Y77, "edp_rst#"); gpio_direction_output(EXYNOS5420_GPIO_Y77, 1); /* EDP_RST# */ + gpio_request(EXYNOS5420_GPIO_X26, "edp_hpd"); gpio_direction_input(EXYNOS5420_GPIO_X26); /* EDP_HPD */ gpio_set_pull(EXYNOS5420_GPIO_X26, S5P_GPIO_PULL_NONE); @@ -88,6 +91,7 @@ void exynos_lcd_power_on(void) void exynos_backlight_on(unsigned int onoff) { /* For PWM */ + gpio_request(EXYNOS5420_GPIO_B20, "backlight_on"); gpio_cfg_pin(EXYNOS5420_GPIO_B20, S5P_GPIO_FUNC(0x1)); gpio_set_value(EXYNOS5420_GPIO_B20, 1); -- cgit v1.2.1
