Hi,
I'm developing on a AM1808 based board (w sdk 5.03.02.00).
My board features a graphical LCD. This LCD is natively 240x320 (portrait), while I need a 320x240 configuration (landscape).
First of all, in drivers/video/da8xx-fb.c I've added parameters definition for this display under the relevant struct:
static struct da8xx_panel known_lcd_panels[] = {
...
/* Tianma TM035HBHT1 */
[1] = {
.name = "Tianma_TM035HBHT1",
.width = 240, /* hor. resolution */
.height = 320, /* ver. resolution */
.hfp = 10, /* hor. front porch */
.hbp = 60, /* hor. back porch */
.hsw = 2, /* HSYNC pulse widht */
.vfp = 4, /* ver. front porch */
.vbp = 4, /* ver. back porch */
.vsw = 310, /* VSYNC pulse widht */
.pxl_clk = 4608000, /* 320*240*60 */
.invert_pxl_clk = 1, /* set 1/0 if RGB is sampled on rising/falling edge of CK */
},
};
As expected, I can see the sdk demo's images on LCD in portrait mode.
Now I want to permanently change the LCD orientation in landscape mode .
Unfortunately the LCD's controller (ILI9340) doesn't support an embedded command for display rotation (90 degrees clockwise in my case),
then I suppose to have to take care of rotating the image in the davinci fb driver.
Can someone give me an example/suggestion on how to patch the drivers/video/da8xx-fb.c in order to do this job ?
Regards,
