Hello all,
I have been moving from the ti 2.6.37 BSP to the 3.x kernel with quite a bit of
success, the main issue I have at the moment is trying to get the frame buffer
and any displays I have initialised.
[ 2.805358] omapfb omapfb: no driver for display: lcd
[ 2.810729] omapfb omapfb: no displays
[ 2.814666] omapfb omapfb: failed to setup omapfb
I have tried a few versions of release and none of them will initialise;
Currently on
[ 0.000000] Linux version 3.6.0-rc3
I have started with board-am3517evm display config and even that doesn't
initialise. Is there something I am missing with the configs or is there a
patch required to get the feature to work.
My current config options use;
#
# Graphics support
#
CONFIG_DRM=y
CONFIG_FB=y
CONFIG_FB_CFB_FILLRECT=y
CONFIG_FB_CFB_COPYAREA=y
CONFIG_FB_CFB_IMAGEBLIT=y
#
# Frame buffer hardware drivers
#
CONFIG_OMAP2_VRAM=y
CONFIG_OMAP2_VRFB=y
CONFIG_OMAP2_DSS=y
CONFIG_OMAP2_VRAM_SIZE=12
CONFIG_OMAP2_DSS_DPI=y
CONFIG_OMAP2_DSS_VENC=y
CONFIG_OMAP2_DSS_DSI=y
CONFIG_OMAP2_DSS_MIN_FCK_PER_PCK=1
CONFIG_OMAP2_DSS_SLEEP_AFTER_VENC_RESET=y
CONFIG_FB_OMAP2=y
CONFIG_FB_OMAP2_NUM_FBS=3
#
# OMAP2/3 Display Device Drivers
#
CONFIG_PANEL_GENERIC_DPI=y
CONFIG_PANEL_SHARP_LS037V7DW01=y
CONFIG_BACKLIGHT_LCD_SUPPORT=y
CONFIG_LCD_CLASS_DEVICE=y
CONFIG_BACKLIGHT_CLASS_DEVICE=y
CONFIG_BACKLIGHT_GENERIC=y
And the init structs are
static int am3517_evm_panel_enable_lcd(struct omap_dss_device *dssdev)
{
gpio_set_value(TAM3517_DVI_PON_GPIO, 0);
gpio_set_value(TAM3517_LCD_ENVDD_GPIO, 0);
gpio_set_value(TAM3517_LCD_PON_GPIO, 1);
printk("LCD voltage on\n");
return 0;
}
static void am3517_evm_panel_disable_lcd(struct omap_dss_device *dssdev)
{
gpio_set_value(TAM3517_LCD_ENVDD_GPIO, 1);
gpio_set_value(TAM3517_LCD_PON_GPIO, 0);
}
static struct panel_generic_dpi_data lcd_panel = {
// .name = "generic_dpi_panel",
.platform_enable = am3517_evm_panel_enable_lcd,
.platform_disable = am3517_evm_panel_disable_lcd,
};
static struct omap_dss_device am3517_evm_lcd_device = {
.type = OMAP_DISPLAY_TYPE_DPI,
.name = "lcd",
.driver_name = "generic_dpi_panel",
.data = &lcd_panel,
.phy.dpi.data_lines = 16,
};
static int am3517_evm_panel_enable_tv(struct omap_dss_device *dssdev)
{
return 0;
}
static void am3517_evm_panel_disable_tv(struct omap_dss_device *dssdev)
{
}
static struct omap_dss_device am3517_evm_tv_device = {
.type = OMAP_DISPLAY_TYPE_VENC,
.name = "tv",
.driver_name = "venc",
.phy.venc.type = OMAP_DSS_VENC_TYPE_SVIDEO,
.platform_enable = am3517_evm_panel_enable_tv,
.platform_disable = am3517_evm_panel_disable_tv,
};
static struct tfp410_platform_data dvi_panel = {
.power_down_gpio = -1,
};
static struct omap_dss_device am3517_evm_dvi_device = {
.type = OMAP_DISPLAY_TYPE_DPI,
.name = "dvi",
.driver_name = "tfp410",
.data = &dvi_panel,
.phy.dpi.data_lines = 24,
};
static struct omap_dss_device *am3517_evm_dss_devices[] = {
&am3517_evm_lcd_device,
// &am3517_evm_tv_device,
// &am3517_evm_dvi_device,
};
static struct omap_dss_board_info am3517_evm_dss_data = {
.num_devices = ARRAY_SIZE(am3517_evm_dss_devices),
.devices = am3517_evm_dss_devices,
.default_device = &am3517_evm_lcd_device,
};
And the device initialised with
omap_display_init(&am3517_evm_dss_data);
Any help feedback appreciated.
Thanks
Marc
