Hello,
Has Touch screen been validated in Dragonboard 820c?
I am Using Raydium68200 5.5 inch TFT 720*1280 Pixels Touch screen panel.
Is there any procedure is available to test the feature and Which driver is used for dsi panel touch screen support?

Thanks,
Ajith.

first you should check which interface is used by your touch hardware, either spi/usb/i2c, then configure the touch driver accordingly.

DSI has absolutely nothing at all to do with touchscreen.
While you may have a DSI panel WITH a touchscreen glued onto it, they are actually two separate parts altogether.

There is really nothing to “validate”. Any board will work with a touchscreen, as long as you wire it in correctly, and have a driver supporting that touchscreen controller built into your kernel and properly configured.
