TDA4VM: How to configure DPI0 to output 1080P RGB888 parallel signal to drive LCD screen under Linux?

Hi Gary,

Currently checking with my team members to see if we have a guide, but I am not aware of a guide specifically for DP bring up on Linux. However, what we can offer is some code/documentation that customers can reference for bring up in general + general display software information.

For general board bring up, we have this academy module that links to a FAQ: https://dev.ti.com/tirex/explore/node?node=A__AZIWszT9XCzrnjlLSYT5tQ__TDA4VM-ACADEMY__dS93ClC__LATEST

I think a start would be for the customer to use the above FAQ for general procedure like pin muxing, and then referencing a working DTS example such as this one for our EVM board: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-j721e-common-proc-board.dts?h=ti-linux-5.10.y

Then, if a change needs to be made at the kernel driver-level, they can reference the DSS (display sub system) documentation from the SDK to learn which files are relevant, and learn available Linux commandline tools useful for debug: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/09_00_00_08/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Display/DSS7.html
