[PATCH 0/2] Support for Synaptics TDDI series panels

From: Kaustabh Chakraborty
Date: Thu Jun 12 2025 - 10:54:01 EST


Synaptics' Touch and Display Driver Integration (TDDI) technology [1]
employs a single chip for both touchscreen and display capabilities.
Such designs reportedly help reducing costs and power consumption.

Although the touchscreens, which are powered by Synaptics'
Register-Mapped Interface 4 (RMI4) touch protocol via I2C or SPI have
driver support in the kernel, the MIPI DSI display panels don't.

This series introduces a rudimentary driver for controlling said display
panels, which supports TD4101 and TD4300 panels.
