From: Marcus Cooper
The default value of the config register is different on newer
SoCs and therefore enabling/disabling with a register write
will clear bits used to set the direction of the clock and frame
pins.

The newer SoCs do not have this setting. Instead they set the pin
direction. Add a check to see if the bit is valid and if so set
it accordingly.

On the newer SoCs the bits to configure the operational mode are
located in a different register. Add a regmap field so that this
location can be configured.

To get i2s working some additional patches are required which will be
delivered later. For now they have been pushed here

I don't own a A33 device which uses the i2s block for the audio codec
so if someone could
From: Marcus Cooper
The BCLKDIV and MCLKDIV found on newer SoCs start from an offset of 1.
Add the functionality to adjust the division values according to the
needs to the device being used.

From: Marcus Cooper
The sun8i-h3 introduces a lot of changes to the i2s block such
as different register locations, extended clock division and
more operational modes. As we have to consider the earlier
implementation then these changes need to be isolated.

From: Marcus Cooper
In preparation for changing this driver to support newer SoC
implementations then where needed there has been a switch from
regmap_update_bits to regmap_field. Also included are adjustment
variables although they are not set as no adjustment is required
for the current support
From: Marcus Cooper
The set_fmt function pointer is called during probing and this is whilst
the block is disabled. It is over writing the default register values with
the same settings so isn't noticed.
This wasn't a problem with the older SoCs but with the desire to reuse as
much functionlity a

ASoC: sun4i-i2s: Add more quirks for newer SoCs
From: Marcus Cooper
There are a lot of changes to the sun8i-h3 i2s block but not enough
to warrant to a new driver.
