Richard Hughes c4ca026294 Allow devices to build instance IDs more easily
Provide a device instance builder that allows plugins to easily
create multiple instance IDs based on parent attributes.

Also fix a lot of the instance ID orders, so that we add more generic
IDs first, and more specific IDs after.

Conexant Audio

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

Update Behavior

The firmware is deployed when the device is in normal runtime mode, and the device will reset when the new firmware has been written.

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:

CxaudioChipIdBase

Base integer for ChipID.

Since: 1.3.2

CxaudioSoftwareReset

If the chip supports self-reset.

Since: 1.3.2

CxaudioPatch1ValidAddr

Address of patch location #1.

Since: 1.3.2

CxaudioPatch2ValidAddr

Address of patch location #2.

Since: 1.3.2

External Interface Access

This plugin requires read/write access to /dev/bus/usb.
