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.

Fresco PD

Introduction

This plugin is used to update Power Devlivery devices by Fresco.

Firmware Format

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

This plugin supports the following protocol ID:

  • com.frescologic.pd

GUID Generation

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

  • USB\VID_1D5C&PID_7102&REV_0001
  • USB\VID_1D5C&PID_7102
  • USB\VID_1D5C

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

  • USB\VID_1D5C&PID_7102&CID_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:0x1D5C

External Interface Access

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