The fixed maximum size of IPC message does not allow for large transfers, e.g. for filter data. Currently such messages will be divided into smaller pieces and sent to firmware in multiple chunks. For future IPC, this strategy is not suitable. The maximum IPC message size is limited by host box size which can be known when firmware is ready, so the fw_ready callback can allocate IPC messages with platform-specific sizes instead of the current fixed-size. To be compatible with released firmware, current platforms will still use SOF_IPC_MSG_MAX_SIZE. For future platforms, there will be a new fw_ready function and the platform-specific allocation will take place there. Signed-off-by:

Hello, this is version 5 of the I2S/TDM driver patchset. A big thanks to everyone who has provided their valuable feedback so far. Changes in v5: driver: - change comment style of the first comment to C++ style - make refcount non-atomic, as it's only ever used inside a spinlock - use newer SND_SOC_DAIFMT_CB* defines - change ternary statements to if/else conditions - make _clk_compensation_put return 1 if clock changed - implement set_bclk_ratio callback - always set half frame sync mode in TDM mode - automatically enable mclk-calibrate mode when the clocks for it are specified in the device tree bindings: - add Reviewed-by: Rob Herring - drop rockchip,frame-width property (done by set_bclk_ratio) - drop rockchip,fsync-half-frame property - drop rockchip,mclk-calibrate property dts: - drop empty codec block from Quartz64 device tree Changes in v4: driver: - factor TDE/RDE enable/disable into their own inlined functions - add an RDE disable in a location where it looks like it was forgotten (rxctrl else), judging by corresponding TDE code - remove parentheses around CLK_PPM_MIN/MAX values - wording + titlecasing in the clock compensation control - use if statement in precious_reg instead - refactor rockchip_i2s_io_multiplex to have the switch statements in a function call to make the function less unwieldy - get rid of IS_ERR checks around clk enable/disable calls where already checked before by the probe - reworded some error message strings - fix potential deadlock in txrxctrl found by Sugar Zhang using spin_lock_irqsave - fix potential deadlock in trcm_mode found by Sugar Zhang using spin_lock_irqsave - use devm_platform_get_and_ioremap_resource in probe - only set DMA things if controller has capture/playback ability. Did not move this into init_dai because I'd then need to pass in the res and probe it earlier in the function, and it's also used elsewhere in the probe function - use _get_optional_exclusive for reset controls, as some controllers only have capture or playback capability bindings: - remove status = "okay" since that's the default - change the path configs to be an enum - rename "foo" to "bus" - make resets optional as controller may lack either playback or capture capability, and therefore also doesn't have a reset. At least one reset is still required, because a controller with no playback and no capture is not very useful Changes in v3: driver: - alphabetically sort includes - check pm_runtime_get_sync return value, act on it - remove unnecessary initialisers in set_fmt - use udelay(15) in retry code: 10 retries * 15 = 150, so at worst we wait the full i2s register access delay - fix some weird returns to return directly - use __maybe_unused instead of #ifdef CONFIG_PM_SLEEP, also put __maybe_unused on the runtime callbacks - use (foo) instead of foo in header macros for precedence reasons - when using mclk-calibrate, also turn off/on those clocks during suspend and resume operations - remove mclk_tx and mclk_rx reenablement code in remove - move hclk enablement further down the probe, and disable it on probe failure - make reset controls mandatory, since the bindings state this too - use _exclusive for getting the reset controls - change reset assert/deassert delays to both be 10 usec (thank you Sugar Zhang!) - properly prepare and enable all mclks in probe, especially before calling clk_get_rate on them - if registering PCM fails, also use the cleanup error path instead of returning directly - bring back playback and capture only but in the way Sugar Zhang suggested it: set those modes depending on dma-names - rework clock enablement in general. Probe now always enables these, instead of relying on the pm resume thing - add myself to MAINTAINERS for this driver dt bindings: - fix a description still mentioning clk-trcm in the schema - document rockchip,io-multiplex, a property that describes the hardware as having multiplexed I2S GPIOs so direction needs to be changed dynamically - document rockchip,mclk-calibrate, which allows specifying different clocks for the two sample rate bases and switch between them as needed - dma-names now doesn't have a set order and items can be absent to indicate that the controller doesn't support this mode - add myself to MAINTAINERS for these bindings Changes in v2: - remove ad-hoc writeq and needless (and broken) optimisation in reset assert/deassert. This wouldn't have worked on Big Endian, and would've been pointless on any other platform, as the overhead for saving one write was comparatively big - fix various checkpatch issues - get rid of leftover clk-trcm in schema - set status = "okay" in example in schema instead of "disabled" - change dma-names so rx is first, adjust device trees as necessary - properly reference uint32-array for rx-route and tx-route instead of uint32 - replace trcm-sync with two boolean properties, adjust DT changes accordingly and also get rid of the header file - get rid of rockchip,no-dmaengine. This was only needed for some downstream driver and shouldn't be in the DT - get rid of rockchip,capture-only/playback-only. Rationale being that I have no way to test whether they're needed, and unconditionally setting channels_min to 0 breaks everything - change hclk description in "clocks" Nicolas Frattaroli (4): ASoC: rockchip: add support for i2s-tdm controller ASoC: dt-bindings: rockchip: add i2s-tdm bindings arm64: dts: rockchip: add i2s1 on rk356x arm64: dts: rockchip: add analog audio on Quartz64 .../bindings/sound/rockchip,i2s-tdm.yaml | 198 ++ MAINTAINERS | 7 + .../boot/dts/rockchip/rk3566-quartz64-a.dts | 31 +- arch/arm64/boot/dts/rockchip/rk356x.dtsi | 26 + sound/soc/rockchip/Kconfig | 11 + sound/soc/rockchip/Makefile | 2 + sound/soc/rockchip/rockchip_i2s_tdm.c | 1848 +++++++++++++++++ sound/soc/rockchip/rockchip_i2s_tdm.h | 398 ++++ 8 files changed, 2520 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/sound/rockchip,i2s-tdm.yaml create mode 100644 sound/soc/rockchip/rockchip_i2s_tdm.c create mode 100644 sound/soc/rockchip/rockchip_i2s_tdm.h -- 2.33.0

Recent changes in soc-pcm completely broke basic support for mixers on Intel systems: the filters on BE states prevent the connection of a second mixer input while the back-end is already active. Rather than reverting the changes, which would be problematic for Tegra systems, this patch suggests an additional filter which will only apply to Tegra systems. This is a temporary solution which will have to be revisited - additional issues have been reported with DPCM. Fixes: 0c25db3f ('ASoC: soc-pcm: Don't reconnect an already active BE') Suggested-by:

This patch prepares the introduction of the compress API with SOF. After each fragment is accepted by the DSP we need to inform the userspace applications that they can send the next fragment. This is done via snd_compr_fragment_elapsed. Similar with the PCM case, in order to avoid sending an IPC before the previous IPC is handled we need to schedule a delayed work to call snd_compr_fragment_elapsed(). See snd_sof_pcm_period_elapsed. To sum up this patch offers the following API to SOF code: * snd_sof_compr_init_elapsed_work * snd_sof_compr_fragment_elapsed Note that implementation for compressed function is in a new file selected via CONFIG_SND_SOC_SOF_COMPRESS invisible config option. This option is automatically selected for platforms that support the compress interface. For now only i.MX8 platforms support this. For symmetry we introduce snd_sof_pcm_init_elapsed_work to setup the work struct for PCM case. Signed-off-by:

This operations should be generic as there is nothing Intel specific. This works well for NXP i.MX8 stream IPC ops. We start by moving sof/intel/intel-ipc.c into sof/stream-ipc.c and rename the functions to be generic. Notice that we use newly introduced snd_sof_dsp_mailbox_read instead of sof_mailbox_read, to make sure that we are not bound to existing MMIO memory access, and we allow platform to implement their own memory access routines.
