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.
