This series adds support for Asynchronous Sample Rate Converter (ASRC)
module on Tegra186 and later generations of SoCs. ASRC is a client of
AHUB. The driver and DT support is added to make it work with Tegra
audio graph card. The module can be plugged into audio path using ALSA
mixer controls.
ASRC supports two modes of operation, where it gets the ratio info
from SW and ratio detector module. Presently the support is added for
SW mode.
Changelog:
==========
v1 -> v2:
---------
* Updatated RPM resume call in ASRC driver. Specific register
sequence programming is done before regcache sync.
* Fixed return values of mixer control put() callbacks in
ASRC driver.
* No changes in other patches.

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
