Subject: [PATCH resend v5 0/3] ASoC: cygnus: Add audio support for Broadcom Cygnus SoC

Hi,

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:
http://lkml.iu.edu/hypermail/linux/kernel/1503.3/05434.html

This patchset has been tested on Cygnus wireless audio bcm958305K board.
It is rebased on top of v4.6-rc1 and is available from github:

repo: https://github.com/Broadcom/cygnus-linux/tree/cygnus-sound-v5

Changes from v4:
- Fix power suspend function and add power resume function
- Remove clock initialization code from audio driver to clock framework
Changes from v3:
- Fix the subject lines to match the style for the subsystem
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.
Changes from v1:
- Address code review comments. Fixed print format of type size_t and
pointer.
