Richard Hughes f50ff2c27e Decouple the version format from the version itself 
If we say that the version format should be the same for the `version_lowest`
and the `version_bootloader` then it does not always make sense to set it at
the same time.

Moving the `version_format` to a standalone first-class property also means it
can be typically be set in the custom device `_init()` function, which means we
don't need to worry about *changing* ther version format as set by the USB and
UDev superclass helpers.

Conexant Audio Support

Introduction

This plugin is used to update a small subset of Conexant (now owned by Synaptics) audio devices.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in a modified SREC file format.

This plugin supports the following protocol ID:

  • com.synaptics.synaptics-cxaudio

GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_17EF&PID_3083&REV_0001
  • USB\VID_17EF&PID_3083
  • USB\VID_17EF

These devices also use custom GUID values, e.g.

  • SYNAPTICS_CXAUDIO\CX2198X
  • SYNAPTICS_CXAUDIO\CX21985

Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to USB:0x17EF

Quirk Use

This plugin uses the following plugin-specific quirks:

Quirk Description Minimum fwupd version
ChipIdBase Base integer for ChipID 1.3.2
IsSoftwareResetSupported If the chip supports self-reset 1.3.2
EepromPatchValidAddr Address of patch location #1 1.3.2
EepromPatch2ValidAddr Address of patch location #2 1.3.2
