Richard Hughes 40cd18fa97 Allow using a per-device global percentage completion 
It's actually quite hard to build a front-end for fwupd at the moment
as you're never sure when the progress bar is going to zip back to 0%
and start all over again. Some plugins go 0..100% for write, others
go 0..100% for erase, then again for write, then *again* for verify.

By creating a helper object we can easily split up the progress of the
specific task, e.g. write_firmware().

We can encode at the plugin level "the erase takes 50% of the time, the
write takes 40% and the read takes 10%". This means we can have a
progressbar which goes up just once at a consistent speed.

Realtek RTS54HID

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

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:0x0BDA

Quirk Use

This plugin uses the following plugin-specific quirks:

Rts54TargetAddr

The target address of a child module.

Since: 1.1.3

Rts54I2cSpeed

The I2C speed to operate at (0, 1, 2).

Since: 1.1.3

Rts54RegisterAddrLen

The I2C register address length of commands.

Since: 1.1.3

External Interface Access

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