This is a Linux Kernel Module that provides a driver for the Jinglitai JLT4013A LCD Panel.
The driver enables the use of custom kernels in the Xiegu X6100.
Xiegu did not comply with the GPL 2.0 mandate of the linux kernel, and did not provide the kernel as they have modified it, including this driver, not even upon request.
The driver was written from reverse engineering the vendor's kernel image and
the vendor's Das U-Boot image using Ghidra, plus looking at similar driver code.
Funnily enough, the original code used the MODULE_LICENSE("GPL v2");
macro.
The original author from Xiegu was recorded in the MODULE_AUTHOR macro as
MODULE_AUTHOR("Jet Yee <xieyi@cqxiegu.com>");.
