-# IPTS driver firmware
-This is the driver firmware required for the `intel_ipts` module. It was
-extracted from the `SurfaceBook2_Win10_18362_1904009_0` firmware bundle for
-Windows.
-
-### Filenames
-* `SurfaceTouchServicingKernel*.bin` -> `vendor_kernel.bin`
-* `SurfaceTouchServicingSFTConfig*.bin` -> `config.bin`
-* `SurfaceTouchServicingDescriptor*.bin` -> `vendor_desc.bin`
-* `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:
-```bash
-$ cat intel_desc.bin vendor_desc.bin > hid_desc.bin
-```
-
-### Quirks
-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.
-The descriptor has been patched accordingly.
