[RFC][PATCH 0/7] Add HDMI audio support for HiKey

From: John Stultz
Date: Fri Jul 15 2016 - 22:13:35 EST


This patch set is required for HDMI audio support on HiKey.

This patchset hasn't yet seen the light of lkml, so I suspect
there will be a few revisions, but I wanted to send it out for
an initial review.

The work is mostly that of Andy Green's, but I've taking a swing
at forward porting and cleaning it up where I saw fit. So credit
to Andy and blame to me. Apologies in advance, as I'm not super
familiar with either DMA or ASoC driver.

The one bit missing to have audio fully working is changes to the
adv7511 driver, but most of those changes are still out of tree, so
I'll submit those changes once they land.

Feedback would be very much appreicated!

thanks
