Subject: [PATCHv4 0/4] Motorola Droid 4 Audio Support

Hi,

This adds audio support to Motorola Droid 4. I dropped the
regulator from the DT binding as requested by Mark.

Tested:
 - Playing via both DACs using Speaker, Earpiece, Headphone
 - Recording using internal Mic
 - Volume Controls

Known not to work:
 - 3.5mm detection support (requires closed source firmware,
   needs further investigation)
 - Modem / Bluetooth Audio (needs different DAI/I2S config)

Changes since PATCHv3:
 * Drop regulator from DT binding, request VAUDIO from
   global regulator namespace instead

Changes since PATCHv2:
 * Fix a whitespace issue
 * Fix const notes Takashi provided
 * Fix a DAPM route issue I accidently introduced in v2

Changes since PATCHv1:
 * Add patch from Tony exporting soc_dpcm_runtime_update
 * Integrate DT patch for vaudio initial mode
 * Split dt-binding from codec patch and add Ack from Rob
 * Fix CPCAP position in Kconfig/Makefile
 * Avoid "err +=" constructs
 * Simplify reset function
 * Drop cpcap_audio_read/write helpers
 * Do not use tertiary operator for mute register value
 * Update Input Mux logic
 * Switch from simple-audio-card to audio-graph-card
