Title:
  Chrontel CH7036 chip not supported

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  I'm running a WeTab with ubuntu and the ch7036 chip is not supported.
  There is a driver for the chromebook (called chrontel), but that driver is more or less a hacked daemon that sends some data to the chip and gives me the following error message:

  Found device ID 0x56
  Found revision ID 0x81
  Mode 1366x786 (44)
  1366y786, dot clock 69300000  -Hsync -Vsync
  H: start 1414, end 1446, skew 0, total 1456
  V: start 771, end 777, total 793
  State: 0
  Firmware size = 3295 bytes.
  State: 2
  State: 3
  Timeout waiting for MCU to return EDID
  CH7036 MCU ver 1.41, Device 56 rev 1 capability 0x1
  EDID timed out: Ignore HPD because EDID failed just after firmware load
  Get EDOD Failed (initial block) using 640x480@60
  Could not find a useful resolution. Maybe hardware problem.
