10.1WXGA is a color active matrix TFT LCD module using amorphous silicon TFT's as an active switching devices. It can be supported by the simple-panel driver. Read the panel default edid information: EDID MODE DETAILS name = <NULL> pixel_clock = 71900 lvds_dual_channel = 0 refresh = 0 ha = 1280 hbl = 160 hso = 48 hspw = 32 hborder = 0 va = 800 vbl = 32 vso = 3 vspw = 5 vborder = 0 phsync = + pvsync = - x_mm = 0 y_mm = 0 drm_display_mode .hdisplay = 1280 .hsync_start = 1328 .hsync_end = 1360 .htotal = 1440 .vdisplay = 800 .vsync_start = 803 .vsync_end = 808 .vtotal = 832 There are two modes in the edid: Detailed mode1: Clock 71.900 MHz, 216 mm x 135 mm 1280 1328 1360 1440 hborder 0 800 803 808 832 vborder 0 +hsync -vsync Detailed mode2: Clock 57.500 MHz, 216 mm x 135 mm 1280 1328 1360 1440 hborder 0 800 803 808 832 vborder 0 +hsync -vsync Add the both edid to support more modes for BOE nv101wxmn51. Signed-off-by: Caesar Wang <wxt@xxxxxxxxxxxxxx> --- Changes in v3: - As Stéphane commented on https://patchwork.kernel.org/patch/9465911, add downclock mode for edid. Changes in v2: - fix the vsync_start and vsync_end from the edid. - change the commit. drivers/gpu/drm/panel/panel-simple.c | 45 ++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) diff --git a/drivers/gpu/drm/panel/panel-simple.c b/drivers/gpu/drm/panel/panel-simple.c index 06aaf79..1ce25b5 100644 --- a/drivers/gpu/drm/panel/panel-simple.c +++ b/drivers/gpu/drm/panel/panel-simple.c @@ -668,6 +668,48 @@ static const struct panel_desc avic_tm070ddh03 = { }, }; +static const struct drm_display_mode boe_nv101wxmn51_modes[] = { + { + .clock = 71900, + .hdisplay = 1280, + .hsync_start = 1280 + 48, + .hsync_end = 1280 + 48 + 32, + .htotal = 1280 + 48 + 32 + 80, + .vdisplay = 800, + .vsync_start = 800 + 3, + .vsync_end = 800 + 3 + 5, + .vtotal = 800 + 3 + 5 + 24, + .vrefresh = 60, + }, + { + .clock = 57500, + .hdisplay = 1280, + .hsync_start = 1280 + 48, + .hsync_end = 1280 + 48 + 32, + .htotal = 1280 + 48 + 32 + 80, + .vdisplay = 800, + .vsync_start = 800 + 3, + .vsync_end = 800 + 3 + 5, + .vtotal = 800 + 3 + 5 + 24, + .vrefresh = 48, + }, +}; + +static const struct panel_desc boe_nv101wxmn51 = { + .modes = boe_nv101wxmn51_modes, + .num_modes = ARRAY_SIZE(boe_nv101wxmn51_modes), + .bpc = 8, + .size = { + .width = 217, + .height = 136, + }, + .delay = { + .prepare = 210, + .enable = 50, + .unprepare = 160, + }, +}; + static const struct drm_display_mode chunghwa_claa070wp03xg_mode = { .clock = 66770, .hdisplay = 800, @@ -1748,6 +1790,9 @@ static const struct of_device_id platform_of_match[] = { .compatible = "avic,tm070ddh03", .data = &avic_tm070ddh03, }, { + .compatible = "boe,nv101wxmn51", + .data = &boe_nv101wxmn51, + }, { .compatible = "chunghwa,claa070wp03xg", .data = &chunghwa_claa070wp03xg, }, { -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
