[PATCH v2 0/2] Add support for MikroElektronika PROTO codec

[Codrin Ciubotariu]

This patchset is based on Florian's initial PROTO driver:
https://lkml.org/lkml/2013/5/22/342

My changes made the driver more generic, so that we could connect other
I2S CPU DAIs, by using device-tree.

Tested with sama5d2 I2S driver.

Changes in v2:
 - removed unnecessary code that added constraints for the fixed SYSLK;
 - fixed errors reported by kbuild;	
 - adjusted "mikroe" in vendor prefixes;
 - updated description in Kconfig;

Codrin Ciubotariu (2):
  ASoC: Add driver for PROTO Audio CODEC (with a WM8731)
  ASoC: mikroe-proto: dt-bindings: add DT bindings for PROTO board
