Hi All,

here is a patch series to add some improvements to the sun4i-i2s driver
which is enough to get HDMI audio working on the A83T, A64, H3 and
H5 platforms.

I've dropped a lot of the functionality that was presented earlier in favour
of getting initial HDMI audio delivered. H6 and multi-channel HDMI will
follow shortly.

My test branch for this can be found at
https://github.com/codekipper/linux-sunxi/commits/upstream-i2s , I've been
using a Pine64 to test with; validating the new SoC block with HDMI audio
and ensuring that I've not broken the old block by making sure that the audio
codec still works.

BR,
CK

v6 changes compared to v5 are:
- removed patches for multi-channel and H6 HDMI audio.
- removed patch for 20, 24 and 32 bit (will push support for just 20 and 24bit)
- ditched tdm patches as support has already been added.
- added fix for A83T reg map.

v5 changes compared to v4 are:
- removed delivered patches.
- Added more details to commit messages.
- replaced some reg fields with function calls.
- Added DSP_A and DSP_B support for H3 and later SoCs.
- Added support for the Allwinner H6.

v4 changes compared to v3 are:
- Moved patches around so that the more controversial of patches are
  at the top of the stack.
- Added more details to commit messages.
- Fixed 20bit audio PCM format to use 4 bytes.
- Reduced number of flags used to indicate a new SoC.

v3 changes compared to v2 are:
 - added back slave mode changes
 - added back the use of tdm properties
 - changes to regmap and caching
 - removed loopback functionality
 - fixes to the channel offset mask

v2 changes compared to v1 are:
 - removed slave mode changes which didn't set mclk and bclk div.
 - removed use of tdm and now use a dedicated property.
 - fix commit message to better explain reason for sign extending
 - add divider calculations for newer SoCs.
 - add support for multi-lane i2s data output.
 - add support for 20, 24 and 32 bit samples.
 - add loopback property so blocks can be tested without a codec.
