*`iaPreciseTouchDescriptor.bin` -> `intel_desc.bin` (the same for all models)
*`ipts_fw_config.bin` (custom, the same for all models; https://github.com/ipts-linux-org/ipts-linux-new/commit/63a8944729d989dd98b0fa382fd9693d6a8c097f)
### HID descriptor
The HID descriptor for IPTS devices consists of `intel_desc.bin` and
`vendor_desc.bin` concatinated together by the driver. The result can be
decompiled by various tools found on the internet:
The touchscreen contact count descriptor is incorrectly declared as being reported four times on the Surface Laptops (both 1 and 2, `vendor_desc.bin` in `MSHW0079`).
It is actually reported one time followed by three padding bytes.
