3 fixes for the tda998x.

* 'drm-tda998x-fixes' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  drm/i2c: tda998x: set the CEC I2C address based on the slave I2C address
  drm: tda998x: Fix EDID read timeout on HDMI connect
  drm: tda998x: Protect the page register

The I2C address for the TDA9989 and TDA19989 is fixed at 0x34 but the
two LSBs of the TDA19988's address are set by two configuration pins
on the chip.  Irrespective of the chip, the associated CEC peripheral's
I2C address is based upon the main I2C address.

This patch avoids any special handling required to support systems that
contain multiple TDA19988 devices on the same I2C bus.

When the HDMI cable is disconnected and reconnected, EDID reading
is called too early raising a EDID read timeout.
This patch uses the system work queue to delay the notification
of the HDMI connect/disconnect event.

As the HDMI registers of the TDA998x chips are accessed by pages,
the page register must be protected.

This patch adds a driver for the Analog Devices adv7511. The adv7511 is
a standalone HDMI transmitter chip. It features a HDMI output interface
on one end and video and audio input interfaces on the other.

This builds upon the previous set of fixes which were pulled on 6th July.
Included in this set are:
- an update from Jean-Francois to add the missing reg documentation entry
  to the device tree documentation.
- conversion of the tda998x driver to the component helpers.

* 'tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox:
  drm/i2c: tda998x: add component support
  drm/i2c: tda998x: allow re-use of tda998x support code
  drm/i2c: tda998x: fix lack of required reg in DT documentation

Add component helper support to the tda998x driver.  This permits the
TDA998x to be declared as a separate device in device tree, and bound
at the appropriate moment with a co-operating card driver.

The existing slave_encoder interfaces are kept while there are existing
users of it in order to prevent regressions.

Re-jig the TDA998x code so that we separate the functionality from the
drm slave encoder implementation.  In several places, this is pretty
clearly the correct thing to do, because we can avoid repetitively
having to convert from the drm_encoder to the TDA998x private
structure, particularly with the driver internal functions.

The main motivation behind this change is to allow the code to be
re-used with a standard drm_encoder and drm_connector implementation
based on the component helpers, rather than the slave_encoder system.
The addition of this will be in the following patch.

We keep the slave_encoder interface as there are existing users of
this; we need to give them time to convert and test.

In tda998x_encoder_destroy(), priv->cec is never NULL, so,
remove its test.
