From: Marcus Cooper
The sun4i, sun5i and sun7i SoC families have an SPDIF
block which is capable of playback and capture.
This patch enables the playback of this block for
the sun4i families.

Hi All,
here is a patch series to add some improvements to the sun4i-i2s driver
found whilst getting slave clocking and hdmi audio working on the newer
SoCs. As the LibreELEC project is progressing extremely well then there
has been some activity getting surround sound workin

Although not causing any noticeable issues, the mask for the
channel offset is covering too many bits.

We have a number of flags used to identify the functionality
of the IP block found on the sun8i-h3 and later devices. As it
is only neccessary to identify this new block then replace
these flags with just one.

The i2s block can be used to pass PCM data over multiple channels
and is sometimes used for the audio side of an HDMI connection.

The i2s block supports multi-lane i2s output however this functionality
is only possible in earlier SoCs where the pins are exposed and for
the i2s block used for HDMI audio on the later SoCs.
To enable this functionality, an optional property has been added to
the bindings.
From: Marcus Cooper
Bypass the regmap cache when flushing the i2s FIFOs and modify the tables
to reflect this.

On the newer SoCs this is set by default to transfer a 0 after
each sample in each slot. However the platform that this driver
was developed on had the default setting where it padded the
audio gain with zeros. This isn't a problem whilst we have only
support for 16bit audio b
From: Marcus Cooper
Some codecs require a different amount of a bit clocks per frame than
what is calculated by the sample width. Use the tdm slot bindings to
provide this mechanism.

Extend the functionality of the driver to include support of 20 and
24 bits per sample for the earlier SoCs.
Newer SoCs can also handle 32bit samples.

Whilst testing the capture functionality of the i2s on the newer
SoCs it was noticed that the recording was somewhat distorted.
This was due to the offset not being set correctly on the receiver
side.

The Allwinner H3 has some differences to its I2S block such as a
different address for the TXFIFO and various register changes.
This patch prepares the driver for these changes.
