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.
