Currently VoodooI2C is disabled due to none of I2C devices on Surface series is usable (Ambient Light Sensor can be enabled but it readings are not properly configured)

VoodooI2C is a project consisting of macOS kernel extensions that add support for I2C bus devices. This kext is intended to be installed by anyone whose computer requires some form of I2C support. It consists of I2C controller drivers and is responsible for publishing device nubs to the IOService plane.

The following Intel I2C controllers are fully supported:

1. INT33C2 and INT33C3 - Haswell era
2. INT3432 and INT3433 - Broadwell era
3. pci8086,9d60, pci8086,9d61, pci8086,9d62 and pci8086,9d63 - Skylake era
4. pci8086,a160, pci8086,a161, pci8086,a162 and pci8086,a163 - Kaby Lake era
5. pci8086,9de8, pci8086,9de9, pci8086,9dea and pci8086,9deb - Cannon Lake/Whiskey Lake era
6. pci8086,a368, pci8086,a369, pci8086,a36a and pci8086,a36b - Coffee Lake era
7. pci8086,2e8, pci8086,2e9, pci8086,2ea, pci8086,2eb, pci8086,6e8, pci8086,6e9, pci8086,6ea and pci8086,6eb- Comet Lake era
8. pci8086,34e8, pci8086,34e9, pci8086,34ea and pci8086,34eb - Ice Lake era

The following device classes are fully supported:

1. I2C-HID devices
2. ELAN devices
3. FTE devices

Note that there is sometimes an overlap between device classes. For example, some ELAN devices may also be I2C-HID devices.

The following UART devices are supported:

34a88086 clk_rate 64000000 baud_rate 4000000 -> divisor 1, clk_config M=8 N=15

9d278086 clk_rate 48000000 baud_rate 3000000 -> divisor 1, clk_config M=2 N=5 (in this config it is usable but produces a lot of transmission errors, further investigations are needed)

Interrupt mode is not realised due to the failure of interrupt registration
