From 4328fb05bf8c90e96afa023d39395efa5fb2fda5 Mon Sep 17 00:00:00 2001 From: Robert Winkler Date: Thu, 2 Oct 2014 12:16:31 -0700 Subject: [PATCH] nitrogen6x: display: add support lvds jeida screen Add support for Boundary Devices 7" and 10.1" 1280x800 displays with integrated FocalTech ft5x06 10-point touch controller. Because they share the touch controller with the 1024x600 displays, auto-detection is disabled and you must explicitly set the 'panel' environment variable: U-Boot > setenv panel LDB-WXGA U-Boot > saveenv && reset Signed-off-by: Robert Winkler Signed-off-by: Eric Nelson --- board/boundary/nitrogen6x/nitrogen6x.c | 31 ++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) diff --git a/board/boundary/nitrogen6x/nitrogen6x.c b/board/boundary/nitrogen6x/nitrogen6x.c index 67d4154480..39e8013480 100644 --- a/board/boundary/nitrogen6x/nitrogen6x.c +++ b/board/boundary/nitrogen6x/nitrogen6x.c @@ -474,6 +474,17 @@ static void enable_lvds(struct display_info_t const *dev) gpio_direction_output(LVDS_BACKLIGHT_GP, 1); } +static void enable_lvds_jeida(struct display_info_t const *dev) +{ + struct iomuxc *iomux = (struct iomuxc *) + IOMUXC_BASE_ADDR; + u32 reg = readl(&iomux->gpr[2]); + reg |= IOMUXC_GPR2_DATA_WIDTH_CH0_24BIT + |IOMUXC_GPR2_BIT_MAPPING_CH0_JEIDA; + writel(reg, &iomux->gpr[2]); + gpio_direction_output(LVDS_BACKLIGHT_GP, 1); +} + static void enable_rgb(struct display_info_t const *dev) { imx_iomux_v3_setup_multiple_pads( @@ -502,6 +513,26 @@ struct display_info_t const displays[] = {{ .vsync_len = 10, .sync = FB_SYNC_EXT, .vmode = FB_VMODE_NONINTERLACED +} }, { + .bus = 0, + .addr = 0, + .pixfmt = IPU_PIX_FMT_RGB24, + .detect = NULL, + .enable = enable_lvds_jeida, + .mode = { + .name = "LDB-WXGA", + .refresh = 60, + .xres = 1280, + .yres = 800, + .pixclock = 14065, + .left_margin = 40, + .right_margin = 40, + .upper_margin = 3, + .lower_margin = 80, + .hsync_len = 10, + .vsync_len = 10, + .sync = FB_SYNC_EXT, + .vmode = FB_VMODE_NONINTERLACED } }, { .bus = 2, .addr = 0x4,
