ASoC: Intel: Add PM support to HSW/BDW PCM driver Add PM and RTD3 support to the HSW/BDW PCM driver. The PCM driver will now save DSP context and then power off the DSP when it's not in use. DSP power and context is then restored when it's next used. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

ASoC: Intel: Work around to fix HW D3 potential crash issue When using clock gatings to save power, there are some known issues: 1. core clock gating (DCLCGE) must be disabled during D0 and D3 entry and updating SRAM banks (VDRTCTL0). 2. DSP trunk clock gating (DTCGE) can cause FW crashes, disable it in D0. To align with the new W/A flow from FW team, we must set VDRTCTL0.D3PGD to 1 (D3 power gating disabled) at first startup and keep it all the time. ADSP will be in D0 on first boot by BIOS part of WA. Required delays must be preserved (waiting for HW to stabilize, after enabling CCG, changing SRAM PG, D3PG). D3->D0: 1. Disable core clock gating (VDRTCTL2.DCLCGE = 0) 2. Enable other CG apart from DTCG and DCLCG (VDRTCTL2. DCLCGE and DTCGE = 0) 3. Disable D3PG (VDRTCTL0.D3PGD = 1) 4. Power up necessary SRAM and wait at least for 18 clock cycles for every bank you have powered up 5. Set D0 state(PMCS.PS = 0), wait for HW 6.

ASoC: Intel: Make ADSP memory block allocation more generic Current block allocation is tied to block type and requestor type. Make the allocation more generic by removing the struct module parameter and adding a generic block allocator structure. Also pass in the list that the blocks have to be added too in order to remove dependence on block requestor type. ASoC: Intel: update scratch allocator to use generic block allocator Update the scratch allocator to use the generic block allocator and calculate total scratch buffer size. ASoC: Intel: Add call to calculate offsets internally within the DSP. A call to calculate internal DSP memory addresses used to allocate persistent and scartch buffers. ASoC: Intel: Add runtime module support. Add support for runtime module objects that can be created for every FW module that is parsed from the FW file. This gives a 1:N mapping between the FW module from file and the runtime instantiations of that module. We also need to make sure we remove every module and runtime module when we unload the FW. ASoC: Intel: Add DMA firmware loading support Add support for DMA to load firmware modules to the DSP memory blocks. Two DMA engines are supported, DesignWare and Intel MID. ASoC: Intel: Add runtime module lookup API call Add an API to allow quick lookup of runtime modules based on ID. ASoC: Intel: Provide streams with dynamic module information Remove the hard coded module paramaters and provide each module with dynamically generated buffer information for scratch and persistent buffers.
