From 11d80af4876b609832856853b63d06a1011bccf1 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 9 Jan 2013 04:55:09 +0000 Subject: [PATCH] mx51evk: Add DVI output support Add DVI output support and make it the default video output. Currently the CLAA WVGA panel is supported, but this panel has to be purchased separately, so using the DVI output as the default would allow more people to try the splash screen feature on a mx51evk. If someone still wants to use the CLAA WVGA, just set the panel variable as: set panel claa Signed-off-by: Fabio Estevam --- board/freescale/mx51evk/mx51evk.c | 2 -- board/freescale/mx51evk/mx51evk_video.c | 39 +++++++++++++++++++++++-- 2 files changed, 36 insertions(+), 5 deletions(-) diff --git a/board/freescale/mx51evk/mx51evk.c b/board/freescale/mx51evk/mx51evk.c index d1ef431895..54c16b1f9d 100644 --- a/board/freescale/mx51evk/mx51evk.c +++ b/board/freescale/mx51evk/mx51evk.c @@ -489,8 +489,6 @@ int board_init(void) /* address of boot parameters */ gd->bd->bi_boot_params = PHYS_SDRAM_1 + 0x100; - lcd_enable(); - return 0; } diff --git a/board/freescale/mx51evk/mx51evk_video.c b/board/freescale/mx51evk/mx51evk_video.c index f036cf73b2..7be5c9befc 100644 --- a/board/freescale/mx51evk/mx51evk_video.c +++ b/board/freescale/mx51evk/mx51evk_video.c @@ -48,6 +48,22 @@ static struct fb_videomode const claa_wvga = { .vmode = FB_VMODE_NONINTERLACED }; +static struct fb_videomode const dvi = { + .name = "DVI panel", + .refresh = 60, + .xres = 1024, + .yres = 768, + .pixclock = 15385, + .left_margin = 220, + .right_margin = 40, + .upper_margin = 21, + .lower_margin = 7, + .hsync_len = 60, + .vsync_len = 10, + .sync = 0, + .vmode = FB_VMODE_NONINTERLACED +}; + void setup_iomux_lcd(void) { /* DI2_PIN15 */ @@ -73,9 +89,26 @@ void setup_iomux_lcd(void) gpio_direction_output(MX51EVK_LCD_BACKLIGHT, 1); } -void lcd_enable(void) +int board_video_skip(void) { - int ret = ipuv3_fb_init(&claa_wvga, 1, IPU_PIX_FMT_RGB565); + int ret; + char const *e = getenv("panel"); + + if (e) { + if (strcmp(e, "claa") == 0) { + ret = ipuv3_fb_init(&claa_wvga, 1, IPU_PIX_FMT_RGB565); + if (ret) + printf("claa cannot be configured: %d\n", ret); + return ret; + } + } + + /* + * 'panel' env variable not found or has different value than 'claa' + * Defaulting to dvi output. + */ + ret = ipuv3_fb_init(&dvi, 0, IPU_PIX_FMT_RGB24); if (ret) - printf("LCD cannot be configured: %d\n", ret); + printf("dvi cannot be configured: %d\n", ret); + return ret; } -- 2.39.2
