thanks for sending a new version of this series.

AFAIK Lee Jones has a new kernel.org address the old linaro address
shouldn't be used anymore. We don't get any further without him.

We don't have an Ack for this display driver. Maybe we should ask Maxime
Ripard and Noralf Trønnes especially Pavel Machek had concerns about the
right subsystem?

In case you want to send a new version it would be nice to enable the
driver in bcm2835_defconfig for better test coverage. But this is not a
show stopper.

Best regards
