[PATCH 0/2] ASoC: bcm2835: add support for hifiberry-dac

[kernel at martin.sperl.org]

From: Martin Sperl <kernel at martin.sperl.org>

Add support for the hifiberry-dac hat that can get attached
to a raspberry pi.

This hat also the ti-pcm5102a DAC, so
support for this DAC has been added to codecs.

This is a backport of the drivers in the rpi-downstream
kernel.

Changelog:
* Drivers written by: Florian Meier <florian.meier at koalo.de>
* ref-count patch by Matthias Reichl <hias at horus.com>
* rebased, checkpath fixed and dt-binding documentation added 
  by Martin Sperl <kernel at martin.sperl.org>
