For ACPI we missed to pm_runtime_enable() call which is required to tell PM core that runtime on this device is enabled now. Since this is common to both PCI and APCI move it out. Also for ACPI we do not require pm_runtime_allow() call, so remove that Signed-off-by:

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. Restore MCLK (clkctl.smos, disabled in D3 entry point 4) 7. Stall and reset core, set CSR 8. Enable core clock gating (VDRTCTL2.DCLCGE = 1), delay 50 us 9. Unreset core 10.Load FW, configure PLL and other necessary things 11.Unstall core Changing SRAM PG during D0: 1. Disable core clock gating (VDRTCTL2.DCLCGE = 0) 2. Set PG mask 3. Wait at least for 18 clock cycles for every bank you have powered up 4. Enable core clock gating, delay 50 us D0->D3: 1. Disable core clock gating (DCLCGE = 0) 2. Stall and reset core 3. Power down entire SRAM and wait at least for 18 clock cycles for every bank (Enable SRAM PG (ISRAMPGE = 0x3FF, DSRAMPGE = 0xFFFFF, D3SRAMPGD = 0), remember about preserving VDRTCTL0.D3PGD = 1) 4. Shutdown PLL, disable MCLK(clkctl.smos = 0), Enable DTCG to save power 5. Set D3 state(PMCS.PS = 3), delay 50 us 6. Enable core clock gating, delay 50 us Signed-off-by:

During FW parsing and loading, block_list_prepare() may be called for each raw data block copying and this may made the hsw_block_enable() called mutiple times, which increase block->users many times. The result of this is hsw_block_disable() can't power gated the related block when trying to free the blocks during suspend, and the power gating status also confused. Here check the block user status, only calling enable() for those blocks who has no user yet. Remember that this works correctlly on current case, where there are enough SRAM memory so different module won't share a memory block. For further usage, we may need restructure the struct sst_mem_block to save the module list who is using it. Signed-off-by:

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.
