ASoC: tegra: add tegra30-ahub driver The AHUB (Audio Hub) is a mux/crossbar which links all audio-related devices except the HDA controller on Tegra30. The devices include the DMA FIFOs, DAM (Digital Audio Mixers), I2S controllers, and SPDIF controller. Audio data may be routed between these devices in various combinations as required by board design/application.

ASoC: tegra: support new register layouts in Tegra124 Tegra124 introduces some small changes to the layout of some registers. Modify the affected drivers to program those registers appropriately based on which SoC they're running on. Tegra124 also introduced some new modules on the AHUB configlink register bus. These will require new entries in configlink_clocks[] in the AHUB driver. However, supporting that change likely relies on switching Tegra to the common reset framework, so I'll defer that change for now.

*
* Each TX CIF transmits data into the XBAR. Each RX CIF can receive audio
* transmitted by a particular TX CIF.

* This driver is currently very simplistic; many HW features are not
* exposed; DAMs are not supported, only 16-bit stereo audio is supported,

Modify the affected drivers to program those registers appropriately based on which SoC they're running on. Tegra124 also introduced some new modules on the AHUB configlink register bus. These will require new entries in configlink_clocks[] in the AHUB driver. However, supporting that change likely relies on switching Tegra to the common reset framework, so I'll defer that change for now.

ASoC: tegra: use reset framework Tegra's clock driver now provides an implementation of the common reset API (include/linux/reset.h). Use this instead of the old Tegra- specific API; that will soon be removed. This change also renames "clock"/"clk" to "modules"/"mod" in symbols related to entries in configlink_clocks[], since: - We don't care about clock handles any more, but rather reset handles, so the old name isn't applicable. - It really is a list of modules on the bus, about which we currently only care about reset handles. If we start caring about any other aspect of the modules in the future, we won't have to rename all these symbols again. Note: The addition of "depends COMMON_CLOCK" is something that was missing before, not a new requirement.
