2019-05-03ASoC: SOF: Intel: hda-stream: store stream capabilitiesKeyon Jie2-0/+7
Add stream_max into struct sof_intel_hda_dev to store the total hda stream number that the platform can support, and initialize it at stream_init. This can be used later e.g. for stream bitmask.

2019-05-03ASoC: SOF: Intel: hda-ipc: simplify handling of IPC IRQKeyon Jie3-13/+5
When using a shared IRQ between IPC interrupt and stream IOC interrupt, the interrupt handlers need to check the interrupt source before scheduling their respective IRQ threads. In the case of IPC handler, it should check if it is an IPC interrupt before waking up the IPC IRQ thread. The IPC IRQ thread, once scheduled, does not need to check the IRQ source again. So, remove the superfluous check in the thread. Remove the irq_status field from snd_sof_dev struct also as it is no longer needed.

2019-05-03ASoC: SOF: PCM: add period_elapsed work to fix race condition in interrupt contextKeyon Jie2-0/+50
The IPC implementation in SOF requires sending IPCs serially: we should not send a new IPC command to the firmware before we get an ACK (or time out) from firmware, and the IRQ processing is complete. snd_pcm_period_elapsed() can be called in interrupt context before IRQ_HANDLED is returned. When the PCM is done draining, a STOP IPC will then be sent, which breaks the expectation that IPCs are handled serially and leads to IPC timeouts. This patch adds a workqueue to defer the call to snd_pcm_elapsed() after the IRQ is handled.

2019-05-03ASoC: SOF: Intel: hda: set I2S slave before enabling DSPZhu Yingjiang2-0/+17
By default, the I2S ports are configured in master mode during DSP powerup sequences, the FS and BCLK lines will be driven on startup, even when the topology file explicitly requires the SSP to be slave. This may be problematic for external components configured in master mode who don't expect the Intel SOC/PCH to drive. Fix by configuring the SSP as slave before the SSP outputs are enabled to avoid this transient behavior. When the topology file configures the SSP as clock master, the initial slave configuration will be overridden.

2019-04-28ASoC: SOF: Add Sound Open Firmware KControl supportLiam Girdwood1-0/+552
SOF exposes regular ALSA Kcontrols that are defined by topology. This patch converts the Kcontrol IO to DSP IPC. The current implementation is aligned with previous Intel solutions, but is not optimal and can be improved: a) for every get/put the host wakes up the DSP and generates an IPC. The kernel should cache the values and generate an IPC only when strictly necessary. b) the firmware can be implemented to only instantiate the pipelines and related control-related parts that are needed at a given time, and power-gate the relevant SRAM blocks. The development tasks for these two improvements has started, once validated they will be provided in an update.

The Sound Open Firmware driver core is a generic architecture independent layer that allows SOF to be used on many 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.
