From: Thierry Reding <treding@nvidia.com>

This small series addresses a minor issue with how IOMMU support is
wired up on various Tegra generations. Currently the virtual "card"
device is used to allocate DMA memory for, but since that device does
not actually exist, the path to memory cannot be correctly described.

To address this, this series moves to using the ADMAIF as the DMA device
for audio. This is a real device that can have a proper DMA mask set and
with which a stream ID can be associated with in the SMMU. The memory
accesses technically originate from the ADMA controller (that the ADMAIF
uses), but DMA channel are dynamically allocated at runtime while DMA
memory is allocated at driver load time, drivers won't have access to
the ADMA device yet.

Further patches will be required to correct this issue on Tegra186 and
Tegra210, but I wanted to get feedback on this approach first.

Changes in v2:
- add backwards-compatibility fallback

Hi Mark

These are v3 of parsing for daifmt.

I want to add new audio-graph-card2 sound card driver,
and this is last part of necessary soc-core cleanup for it.

Current some drivers are using DT, and then,
snd_soc_of_parse_daifmt() parses daifmt, but bitclock/frame provider
parsing part is one of headache, because we are assuming below both cases.

A)	node {
		bitclock-master;
		frame-master;
		...
	};

B)	link {
		bitclock-master = <&xxx>;
		frame-master = <&xxx>;
		...
	};

The original was style A), and style B) was added later.

snd_soc_of_parse_daifmt() parses A) style as original style,
and user need to update to B) style for clock_provider part if needed.

To handle it more flexibile, this patch-set adds new functions
which separates snd_soc_of_parse_daifmt() helper function.

	snd_soc_daifmt_parse_format()			: format part
	snd_soc_daifmt_parse_clock_provider_as_flag()	: clock part for style A)
	snd_soc_daifmt_parse_clock_provider_as_phandl()	: clock part for style B)
	snd_soc_daifmt_parse_clock_provider_as_bitmap()	: clock part use with _from_bitmap

v1 -> v2
	- tidyup parse_clock_provider functions to _as_flag/phandle/bitmap()
	- don't exchange code style on each drivers.

v2 -> v3
	- use daifmt as much as possible (don't use daiclk) on each driver.
