[v3,00/10] add ASoC components for AHUB

Overview
========
The Audio Hub (AHUB) is part of the Audio Processing Engine (APE) which
comprises a collection of hardware accelerators for audio pre-processing
and post-processing. It also includes a programmable full crossbar for
routing audio data across these accelerators.

This series exposes some of these below mentioned HW devices as ASoC
components for Tegra platforms from Tegra210 onwards.
 * ADMAIF : The interface between ADMA and AHUB
 * XBAR   : Crossbar for routing audio samples across various modules
 * I2S    : Inter-IC Sound Controller
 * DMIC   : Digital Microphone
 * DSPK   : Digital Speaker

Following is the summary of current series.
 1. Add YAML DT binding documentation for above mentioned modules.
 2. Helper function for ACIF programming is exposed for Tegra210 and later.
 3. Add ASoC driver components for each of the above modules.
 4. Add DT entries for above components for Tegra210, Tegra186 and
    Tegra194.
 5. Enable these components for Jetson-Tx1, Jetson-Tx2 and Jetson-Xavier.

Machine driver series will be sent separately.

Changelog
=========

   - Removed tegra_cif.c
   - Instead added inline helper function in tegra_cif.h

 * common changes (for patch [3/10] to [7/10])
   - Replace LATE system calls with Normal sleep
   - Remove explicit RPM suspend in driver remove() call
   - Use devm_kzalloc() instead of devm_kcalloc() for single element

   (New patch)
   - Enables ACONNECT and AHUB components. With this AHUB and components are
     registered with ASoC core.

v1 -> v2
--------
 * [1/9] "dt-bindings: sound: tegra: add DT binding for AHUB"
   - no changes

 * [2/9] "ASoC: tegra: add support for CIF programming"
   - removed CIF programming changes for legacy chips.
   - this patch now exposes helper function for CIF programming,
     which can be used on Tegra210 later.
   - later tegra_cif.c can be extended for legacy chips as well.
   - updated commit message accordingly

 * [3/9] "ASoC: tegra: add Tegra210 based DMIC driver"
   - removed unnecessary initialization of 'ret' in probe()

 * [4/9] "ASoC: tegra: add Tegra210 based I2S driver"
   - removed unnecessary initialization of 'ret' in probe()
   - fixed indentation
   - added consistent bracing for if-else clauses
   - updated 'rx_fifo_th' type to 'unsigned int'
   - used BIT() macro for defines like '1 << {x}' in tegra210_i2s.h

 * [5/9] "ASoC: tegra: add Tegra210 based AHUB driver"
   - used of_device_get_match_data() to get 'soc_data' and removed
    explicit of_match_device()
   - used devm_platform_ioremap_resource() and removed explicit
    platform_get_resource()
   - fixed indentation for devm_snd_soc_register_component()
   - updated commit message
   - updated commit message to reflect compatible binding for Tegra186 and
     Tegra194.

 * [6/9] "ASoC: tegra: add Tegra186 based DSPK driver"
   - removed unnecessary initialization of 'ret' in probe()
   - updated 'max_th' to 'unsigned int'
   - shortened lengthy macro names to avoid wrapping in
     tegra186_dspk_wr_reg() and to be consistent

 * [7/9] "ASoC: tegra: add Tegra210 based ADMAIF driver"
   - used of_device_get_match_data() and removed explicit of_match_device()
   - used BIT() macro for defines like '1 << {x}' in tegra210_admaif.h
   - updated commit message to reflect compatible binding for Tegra186 and
     Tegra194.

 * [8/9] "arm64: tegra: add AHUB components for few Tegra chips"
   - no change

 * [9/9] "arm64: tegra: enable AHUB modules for few Tegra chips"
   - no change

 * common changes for patch [3/9] to [7/9]
   - sorted headers in alphabetical order
   - moved MODULE_DEVICE_TABLE() right below *_of_match table
   - removed macro DRV_NAME
   - removed explicit 'owner' field from platform_driver structure
   - added 'const' to snd_soc_dai_ops structure
