This patchset contains audio support for Broadcom's Cygnus SoC. It
contains DT bindings and core audio driver. The audio driver
supports both capture and playback of Audio PCM samples over I2S/TDM
interface and provides playback support over SPDIF interface.

This patchset is derived from a previously submitted patchset:

This patchset has been tested on Cygnus wireless audio bcm958305K board.
It is based on v4.3-rc5  and is available from github:

repo: https://github.com/Broadcom/cygnus-linux/tree/cygnus-sound-v3

Changes from v2:
 - Split patchset 2/2 from v2 into patchsets 2/3 and 3/3.
 - Remove SND_SOC_CYGNUS_DIAG. Diagnostics can be performed using
   standard kernel trace infrastructure.
 - Fix interrupt handler. Acknowledge only those interrupts that are
   handledby ISR.
 - Modify configure_vco() and the pll_macro_entry() struct to make it
   better readable. The functionality did not change.
 - Remove casts on macros
 - Removed surround sound channel grouping from the driver.
