Hi STM-Team,
We have the custom board based on the STM32MP157DAC board with KLD35176BVIB LCD display.
KLD35176BVIB is actually BOE3.49(VGA) + HX8394f display.
We are using yocto build to configure the display panel changes.
I have attached my device tree configuration
1) I need to configure below pins.
| Pin Name | Pin Number | Function | Implementation | Remarks |
| PA14 | T2 | TP_INT | Touch Panel interrupt | Reference design has only DSI_LCD_INT, combined for Display + TP |
| PD13 | AA19 | DSI_TE | Pin re-mapped | FUNCTION MOVED FROM PC6 TO PD13 |
| PD15 | J2 | DSI_LCD_BL_CTRL | Pin re-mapped | Function moved from PA15 |
| PH6 | Y11 | TP_RESET | | |
I was not able to find how and where to map these pins for my display panel As I am not much familiar with ST pin-mapping I was not able to figure out these mappings.
2) I was also looking for the DSI defaul data and clk pins pinmapping in device tree but not able to find it for below pins.
| DSI_D0P |
| DSI_D0N |
| DSI_D1P |
| DSI_D1N |
| DSI_CK_P |
| DSI_CK_N |
| DSI_RESET |
| DSI_LCD_INT |
3) Additionally is there a display driver available for KLD35176BVIB if yes how to enable it an use it to bring up our display LCD if no which alternative driver can we use since i can't find BOE+hx8394f driver in driver/gpu/drm/panel/ files.
4) I wanted to also know what is the best way to make and track device tree changes for linux-kernel,u-boot, and TFA. Since directly making changes in /tmp folder doesn't seem to be the best solution.
Thanks.
