I am working on i.MX93 platform to bringup a 10" LCD Display (MTF101UG66B-V1) over MIPI DSI interface and am facing issue in getting the display on the LCD.
Here is my device tree node for the dsi interface:
&dsi {
panel@0 {
compatible = "microtech,mtf055fhdi";
reg = <0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_dsi>;
reset-gpio = <&gpio2 19 GPIO_ACTIVE_HIGH>;
dsi-lanes = <4>;
video-mode = <0>;
/* 0: burst mode
* 1: non-burst mode with sync event
* 2: non-burst mode with sync pulse
*/
width-mm = <508>;
height-mm = <318>;
status = "okay";
port {
panel_in: endpoint {
remote-endpoint = <&dsi_out>;
};
};
};
ports {
port@1 {
reg = <1>;
dsi_out: endpoint {
remote-endpoint = <&panel_in>;
};
};
};
};
&lcdif {
status = "okay";
assigned-clock-rates = <537300000U>, <490000000>, <400000000>, <133333333>;
};
I am reusing the driver for a 5” display from the same vendor namely – panel-microtech-mtf055.c by tuning the parameters as per my Display. Before moving on to 10” display, I have tested the 5” Display and it is working fine with the same platform.
Here are the parameters set :
static const struct drm_display_mode microtech_mtf055fhdi_mode = {
.clock = 458000,
.crtc_clock = 458000,
.hdisplay = 1920,
.hsync_start = 1920+112,
.hsync_end = 1920+112+8,
.htotal = 1920+112+8+32,
.vdisplay = 1200,
.vsync_start = 1200+11,
.vsync_end = 1200+11+1,
.vtotal = 1200+11+1+14,
.crtc_hdisplay = 1920,
.crtc_hblank_start = 1920,
.crtc_hblank_end = 1920+112+8,
.crtc_hsync_start= 1920+112,
.crtc_hsync_end = 1920+112+8,
.crtc_htotal = 1920+112+8+32,
.crtc_hskew=0,
.crtc_vdisplay =1200,
.crtc_vblank_start=1200,
.crtc_vblank_end =1200+11+1,
.crtc_vsync_start=1200+11,
.crtc_vsync_end =1200+11+1,
.crtc_vtotal =1200+11+1+14,
.width_mm = 216,
.height_mm = 135,
.flags=DRM_MODE_FLAG_NHSYNC|DRM_MODE_FLAG_NVSYNC
};
Currently there is no display image or pixel seen on the LCD display when I stream an image from the processor. To add that BIST test on the LCD works fine.
I would appreciate any help or guidance for the same.
