[PATCH 0/5] cec/adv/omap: fixes and new status flags

[Hans Verkuil <hverkuil@xs4all.nl>]

From: Hans Verkuil <hans.verkuil@cisco.com>

The first patch adds new status flags to indicate when a pending
message is aborted because the CEC adapter is unconfigured, and when
a transmit times out (this indicates a driver bug).

The second and third patch fix a minor issue with the adv HDMI receivers:
if the EDID goes away, then the physical address also becomes invalid.

The fourth patch fixes a race condition in the omap4 CEC driver that
causes a transmit time out. The final patch drops the code in the omap4
CEC driver that attempts to set the number of retransmits: those register
bits are read-only, so the code is pointless.

There are no dependencies between these patches, although the first
and fourth patch relate to the same problem. With the new transmit
TIMEOUT status I hope that it will be easier to catch driver bugs like
that earlier since this bug remained hidden for too long.

Regards,

	Hans

  cec: add new tx/rx status bits to detect aborts/timeouts
  adv7604: when the EDID is cleared, unconfigure CEC as well
  adv7842: when the EDID is cleared, unconfigure CEC as well
  omapdrm/dss/hdmi4_cec.c: clear TX FIFO before transmit_done
  omapdrm/dss/hdmi4_cec.c: don't set the retransmit count
