From 765f2f083fefbfc1e8fb4ef5e4f32d254b54ed16 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Sat, 3 Aug 2013 07:22:50 +0200 Subject: video, da8xx-fb: changes for am335x usage to use this driver also on am335x based boards, the following changes are made: - struct lcd_ctrl_config lcd_cfg is now configurable through board code - controller base is configurable through define DA8XX_LCD_CNTL_BASE. To be compatible with older da8xx based boards: If this define is missing, the DAVINCI_LCD_CNTL_BASE is used - Determine LCD IP Version, and make the driver working on lcd revision register values: Version 1: 0x4C100102 Version 2: 0x4F200800 0x4F201000 Signed-off-by: Heiko Schocher Cc: Stefano Babic Cc: Anatolij Gustschin Cc: Tom Rini Acked-by: Tom Rini --- board/davinci/ea20/ea20.c | 26 +++++++++++++++++++++++++- 1 file changed, 25 insertions(+), 1 deletion(-) (limited to 'board/davinci/ea20/ea20.c') diff --git a/board/davinci/ea20/ea20.c b/board/davinci/ea20/ea20.c index 89ee079..c4444c7 100644 --- a/board/davinci/ea20/ea20.c +++ b/board/davinci/ea20/ea20.c @@ -43,6 +43,30 @@ static const struct da8xx_panel lcd_panel = { .invert_pxl_clk = 0, }; +static const struct display_panel disp_panel = { + QVGA, + 16, + 16, + COLOR_ACTIVE, +}; + +static const struct lcd_ctrl_config lcd_cfg = { + &disp_panel, + .ac_bias = 255, + .ac_bias_intrpt = 0, + .dma_burst_sz = 16, + .bpp = 16, + .fdd = 255, + .tft_alt_mode = 0, + .stn_565_mode = 0, + .mono_8bit_mode = 0, + .invert_line_clock = 1, + .invert_frm_clock = 1, + .sync_edge = 0, + .sync_ctrl = 1, + .raster_order = 0, +}; + /* SPI0 pin muxer settings */ static const struct pinmux_config spi1_pins[] = { { pinmux(5), 1, 1 }, @@ -259,7 +283,7 @@ int board_init(void) /* address of boot parameters */ gd->bd->bi_boot_params = LINUX_BOOT_PARAM_ADDR; - da8xx_video_init(&lcd_panel, 16); + da8xx_video_init(&lcd_panel, &lcd_cfg, 16); return 0; } -- cgit v1.1
