…fig. Machine drivers statically define a number of DAI links that currently cannot be changed or removed by topology. This means PCMs and platform components cannot be changed by topology at runtime AND machine drivers are tightly coupled to topology. This patch allows topology to override the machine driver DAI link config in order to reuse machine drivers with different topologies and platform components. The patch supports :- 1) create new FE PCMs with a topology defined PCM ID. 2) destroy existing static FE PCMs 3) change the platform component driver. 4) assign any new HW params fixups. The patch requires no changes to the machine drivers, but does add some platform component flags that the platform component driver can assign before loading topologies.

Give topology clients more access to the topology data by passing index, pcm, link_config and dai_driver to clients. This allows clients to fully instantiate and track topology objects. The SOF driver is the first user of these new APIs and needs them to build component topology driver and FW objects. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
Add a callback fro clients for notification about DAPM route loading and unloading. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
Currently ALSA core blocks userspace for about 10 seconds for PCM R/W IO. This needs to be configurable for modern hardware like DSPs where no pointer update in milliseconds can indicate terminal DSP errors. Add a substream variable to set the wait time in ms. This allows userspace and drivers to recover more quickly from terminal DSP errors. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>

Align with firmware tools, no functionality change Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
There is no need to deal with DMICs if the DSP is not present and there is no ACPI machine ID found. Simplify before moving these ACPI tables to sound/soc/intel/common Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
No functionality change, just move to common tables to make it easier to deal with SOF and share the same machine drivers - as done previously for BYT/CHT/HSW/BDW. Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
No functionality change for Skylake driver, add relevant names needed by SOF. Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
The Sound Open Firmware driver core is a generic architecture independent layer that allows SOF to be used on many different different architectures and platforms. It abstracts DSP operations and IO methods so that the target DSP can be an internal memory mapped or external SPI or I2C based device. This abstraction also allows SOF to be run on many different VMs on the same physical HW. SOF also requires some data in ASoC PCM runtime data for looking up SOF data during ASoC PCM operations.

SOF exposes regular ALSA Kcontrols that are defined by topology. This patch converts the Kcontrol IO to DSP IPC. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
Add debugFS files that can be used to expose DSP memories and and peripherals to userspace to assist with firmware debugging. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
Define an IPC ABI for all host <--> DSP communication. This ABI should be transport agnostic. i.e. it should work on MMIO and SPI/I2C style interfaces. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
Add support for exposing PCMs to userspace. PCMs are defined by topology and the operations in this patch map to SOF IPC calls. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
SOF uses topology to define the DAPM graphs and widgets, DAIs, PCMs and set parameters for init and run time usage. This patch loads topology and maps it to IPC commands that are build the topology on the DSP. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
Add a trace event buffer that can be used by userspace to read DSP runtime trace events alongside bespoke trace data in realtime for firmware debug. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
Add operation pointers that can be called by core to control a wide variety of DSP targets. The DSP HW drivers will fill in these operations. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>

Add a simple "fallback" machine driver that can be used to enable SOF on boards with no codec device. This machine driver can also be forced for debug/development. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
