From 3b43ad201dea06be1636e4809278d63837f8d292 Mon Sep 17 00:00:00 2001 From: "Manjunathappa, Prakash" Date: Tue, 16 Oct 2012 10:23:16 +0530 Subject: da8xx-fb: cleanup LCDC configurations Configure below LCDC configurations to optimal values, also have an option configure these optional parameters for platform. 1) AC bias configuration: Required only for passive panels 2) Dma_burst_size: 3) FIFO_DMA_DELAY: 4) FIFO threshold: Does not apply for da830 LCDC. Patch is verified for 16bpp and 24bpp configurations on da830, da850 and am335x EVMs. Signed-off-by: Manjunathappa, Prakash Signed-off-by: Tomi Valkeinen --- arch/arm/mach-davinci/devices-da8xx.c | 22 +--------------------- 1 file changed, 1 insertion(+), 21 deletions(-) (limited to 'arch/arm/mach-davinci') diff --git a/arch/arm/mach-davinci/devices-da8xx.c b/arch/arm/mach-davinci/devices-da8xx.c index bd2f72b414b..fcb30d3ae24 100644 --- a/arch/arm/mach-davinci/devices-da8xx.c +++ b/arch/arm/mach-davinci/devices-da8xx.c @@ -518,29 +518,9 @@ void __init da8xx_register_mcasp(int id, struct snd_platform_data *pdata) } } -static const struct display_panel disp_panel = { - QVGA, - 16, - 16, - COLOR_ACTIVE, -}; - static struct lcd_ctrl_config lcd_cfg = { - &disp_panel, - .ac_bias = 255, - .ac_bias_intrpt = 0, - .dma_burst_sz = 16, + .panel_shade = COLOR_ACTIVE, .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, - .fifo_th = 6, }; struct da8xx_lcdc_platform_data sharp_lcd035q3dg01_pdata = { -- cgit v1.2.3-18-g5258 From 81cec3c7566b8498f93d4f47225241875ab4968c Mon Sep 17 00:00:00 2001 From: Manjunathappa Date: Tue, 20 Nov 2012 18:11:01 +0530 Subject: video: da8xx-fb: clk_get on connection id fck do clk_get on connection id "fck" to support OMAP based platforms having multiple clocks for module.
