* ASoC: tegra: convert to standard DMA DT bindingsStephen Warren2013-12-111-5/+4
| | | | | | | | | | | | By passing no flags when calling snd_dmaengine_pcm_register() from tegra_pcm.c, we end up using dma_request_slave_channel() rather than dmaengine_pcm_compat_request_channel(), and hence rely on the standard DMA DT bindings and stashing the DMA slave ID away during channel allocation. This means there's no need to use a custom DT property to store the slave ID. So, remove all the code that parsed it.

* ASoC: tegra: use reset frameworkStephen Warren2013-12-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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.

* ASoC: tegra: support new register layouts in Tegra124Stephen Warren2013-10-141-1/+37
| | | | | | | | | | | | | | | | 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.

| * ASoC: tegra: add Tegra114 support to the AHUB driverStephen Warren2013-03-251-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra114's AHUB shares a design with Tegra30, with the followin changes: * Supports more (10 vs. 4) bi-directional FIFO channels into RAM. * Requires a separate block of registers to support the above. * Supports more attached clients, i.e. new audio multiplexing and de-multiplexing modules. * Is affected by more clocks due to the above. This change fully defines the device tree binding changes required to represent these changes, and minimally extends the driver to support the new hardware, without exposing any of the new FIFO channels.

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.
