Like A83T the Allwinner H3 doesn't have the DMA reception available for
some audio interfaces.
As it's already documented for A83T convert this to an enum and add the H3
interface.

Hi,
Just some minor changes compare to v6.
As explain in v6 there is no more HDMI soundcard,
I will try to introduce a dedicated Allwinner soundcard
in a next series.

Change since v6:
- move set_channel_cfg() in first position
- convert return value to decimal
Change since v5:
- Drop
We are actually using a complex formula to just return a bunch of
simple values. Also this formula is wrong for sun4i when calling
get_wss() the function return 4 instead of 3.
Replace this with a simpler switch case.
Also drop the i2s params which is unused and return a simple int as
returning

H6 I2S is very similar to that in H3, except it supports up to 16
channels.

On the newer SoCs such as the H3 and A64 this is set by default
to transfer a 0 after each sample in each slot. However the A10
and A20 SoCs that this driver was developed on had a default
setting where it padded the audio gain with zeros.
This isn't a problem while we have

As slots and slot_width can be set manually using set_tdm().
These values are then kept in sun4i_i2s struct.
So we need to check if these values are set or not.
This is not done actually and will trigger a bug.
For example, if we set to the simple soundcard in the device-tree
dai-tdm-slot-width =
Checkpatch script produces warning:
WARNING: function definition argument 'const struct sun4i_i2s *'
should also have an identifier name.
Let's fix this by adding identifier name to get_bclk_parent_rate()
and set_fmt() callback definition.

Because SUN4I_I2S_FIFO_CTRL_REG is volatile, writes done while the
regmap is cache-only are ignored. To work around this, move the
configuration to a callback that runs while the ASoC core has a
runtime PM reference to the device.

The FIFO TX reg is volatile and sun8i i2s register
mapping is different from sun4i.
Even if in this case it's doesn't create an issue,
Avoid setting some regs that are undefined in sun8i.
