Richard Hughes d99f86023f trivial: Add getters to FuChunk 
At the moment FuChunks are sometimes mutable, and sometimes immutable, and it's
all a bit too low level for comfort.

Before we can do any kind of optimisation or verification we need plugins to
stop reading directly from the C structure. The aim here is to make FuChunk
optionally mutable without making assumptions about the memory model, and also
to be able to introspect it for the docs.

Realtek RTS54HID HID Support

Introduction

This plugin allows the user to update any supported hub and attached downstream ICs using a custom HID-based flashing protocol. It does not support any RTS54xx device using the HUB update protocol.

Other devices connected to the RTS54HIDxx using I2C will be supported soon.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format.

This plugin supports the following protocol ID:

  • com.realtek.rts54

GUID Generation

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

  • USB\VID_0BDA&PID_1100&REV_0001
  • USB\VID_0BDA&PID_1100
  • USB\VID_0BDA

Child I²C devices are created using the device number as a suffix, for instance:

  • USB\VID_0BDA&PID_1100&I2C_01

Vendor ID Security

The vendor ID is set from the USB vendor, in this instance set to USB:0x0BDA

Quirk use

This plugin uses the following plugin-specific quirks:

Quirk Description Minimum fwupd version
Rts54TargetAddr The target address of a child module. 1.1.3
Rts54I2cSpeed The I2C speed to operate at (0, 1, 2). 1.1.3
Rts54RegisterAddrLen The I2C register address length of commands 1.1.3

External interface access

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