From d804452bf4e4484d2ea305f3d4dc7ba219298fb3 Mon Sep 17 00:00:00 2001 From: Hannes Petermaier Date: Fri, 24 Apr 2015 14:49:35 +0200 Subject: board/BuR/tseries: take usage of CONFIG_LCD_ROTATION We take use of the new LCD_ROTATION feature. The information about how the display is rotated is taken from B&R specific (/factory-settings/rotation) information in the devicetree. The information there is stored as string (cw, ud, ccw, none) since starting support of this devices and cannot be changed, so we have to convert it into none = 0 cw = 1 ud = 2 ccw = 3 Signed-off-by: Hannes Petermaier --- board/BuR/common/common.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) (limited to 'board/BuR/common/common.c') diff --git a/board/BuR/common/common.c b/board/BuR/common/common.c index 23a98e4..3036f86 100644 --- a/board/BuR/common/common.c +++ b/board/BuR/common/common.c @@ -52,6 +52,9 @@ int load_lcdtiming(struct am335x_lcdpanel *panel) struct am335x_lcdpanel pnltmp; #ifdef CONFIG_USE_FDT u32 dtbprop; + char buf[32]; + const char *nodep = 0; + int nodeoff; if (gd->fdt_blob == NULL) { printf("%s: don't have a valid gd->fdt_blob!\n", __func__); @@ -97,6 +100,25 @@ int load_lcdtiming(struct am335x_lcdpanel *panel) dtbprop = FDTPROP(PATHTIM, "de-active"); if (dtbprop == 0) pnltmp.pol |= DE_INVERT; + + nodeoff = fdt_path_offset(gd->fdt_blob, "/factory-settings"); + if (nodeoff >= 0) { + nodep = fdt_getprop(gd->fdt_blob, nodeoff, "rotation", NULL); + if (nodep != 0) { + if (strcmp(nodep, "cw") == 0) + panel_info.vl_rot = 1; + else if (strcmp(nodep, "ud") == 0) + panel_info.vl_rot = 2; + else if (strcmp(nodep, "ccw") == 0) + panel_info.vl_rot = 3; + else + panel_info.vl_rot = 0; + } + } else { + puts("no 'factory-settings / rotation' in dtb!\n"); + } + snprintf(buf, sizeof(buf), "fbcon=rotate:%d", panel_info.vl_rot); + setenv("optargs_rot", buf); #else pnltmp.hactive = getenv_ulong("ds1_hactive", 10, ~0UL); pnltmp.vactive = getenv_ulong("ds1_vactive", 10, ~0UL); @@ -111,6 +133,7 @@ int load_lcdtiming(struct am335x_lcdpanel *panel) pnltmp.pol = getenv_ulong("ds1_pol", 16, ~0UL); pnltmp.pup_delay = getenv_ulong("ds1_pupdelay", 10, ~0UL); pnltmp.pon_delay = getenv_ulong("ds1_tondelay", 10, ~0UL); + panel_info.vl_rot = getenv_ulong("ds1_rotation", 10, 0); #endif if ( ~0UL == (pnltmp.hactive) || -- cgit v1.1
