[PATCH v3 0/3] Add ANX7814 I2C bridge driver

[Enric Balletbo i Serra]

Hi all,

This is the third version of the patch, thanks to all that did some comments.
Since I got some reviews and acks I'm wondering if would be possible to land
these patches. Otherwise all reviews are welcome.

I'm not sure if there is a drm bridge maintainer, I think Thierry Reding
maintained this in the past but I'm not sure he's still maintaining the bridge
drivers, so who is the most suitable person to pick up the patches if they are
ok? Maybe Dave?

This patch set to introduces the anx7814 slimport transmitter driver. These
new series will replace the old series that can be found here [1]. The reason
why I introduce these new series is because the driver changed significantly.
The old approach used a polled state machine ans was not really well using the
kernel mode setting API. With this new driver I tried to use better the drm API
and use an interrupt driven model.
