ms912x driver for Linux

Linux kernel driver for MacroSilicon USB to VGA/HDMI adapter.

There are two variants:

• VID/PID is 534d:6021. Device is USB 2

• VID/PID is 345f:9132. Device is USB 3

• Improved performance and Driver adaptation for Linux kernel 6.15. by Andrey Rodríguez Araya

• For kernel 6.16 checkout branch kernel-6.16

• For kernel 6.15 checkout branch kernel-6.15

• For kernel 6.12 checkout branch kernel-6.12

• For kernel 6.11 ?

• For kernel 6.8 - 6.10 checkout branch kernel-6.8

TODOs:

• Detect connector type (VGA, HDMI, etc...)
• More resolutions
• Error handling
• Is RGB to YUV conversion needed?

Development

Driver is written by analyzing wireshark captures of the device.
