[PATCH v4 0/5] Update Lpass digital codec macro drivers

[Srinivasa Rao Mandadapu]

This patch set is to add support for lpass sc7280 based targets.
Upadate compatible name and change of bulk clock voting to optional
clock voting in digital codecs va, rx, tx macro drivers.

Changes Since V3:
    -- Removed fixes tag.
    -- Change signedoff by sequence.
Changes Since V2:
    -- Add Tx macro deafults for lpass sc7280
Changes Since V1:
    -- Removed individual clock voting and used bulk clock optional.
    -- Removed volatile changes and fixed default values.
    -- Typo errors.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
