Subject: [PATCH v6 0/7] ASoC: sun4i-i2s: Updates to the driver

From: Marcus Cooper <codekipper@...il.com>

Hi All,
To be able to add support for the Allwinner H6 I've changed some of the
original reg fields into function calls as this made it easier to setup
for multi-channel audio especially across different SoCs. I've also
stripped out all the other patches unrelated to this which I will deliver
after support for the H6 has gone in.

These other patches are required for HDMI audio which is driving this
patchset and they can be found here

BR,
CK

v6 changes compared to v5 are:
- rebased onto the recent tdm delivery
- stripped out patches not required for the H6 delivery

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.
