It serialises and deserialises PCM audio + between system memory and external serial audio peripherals (PCM, TDM, + I2S, MI2S) through the AIF path, and transfers parallel audio between + memory and an internal WCD codec through the CIF path. + + AIF (Audio Interface): up to 13 multi-lane Unified Audio Interfaces, + each supporting up to 8 independent data lanes. Each lane is individually + configurable as TX (output/speaker) or RX (input/mic). All lanes of an + interface share a single bit clock and frame sync. Supported modes are + PCM (short/long sync), TDM, and MI2S (stereo/mono). Per-interface + configuration includes sync source (master/slave), sync mode, sync delay, + sync inversion, slot width (8/16/24/32-bit), sample width, active slot + masks (up to 32 slots), bits-per-lane frame size, lane enable/direction + masks, loopback, output-enable control, and full-cycle path support for + long chip-to-chip connections. + + CIF (Codec Interface): up to 10 RDDMA (playback) and 10 WRDMA (capture) + channels connecting to an internal codec over a parallel bus. Each channel + supports active-channel enable mask (up to 16 channels), frame-sync + selection, frame-sync delay, frame-sync output gating, dynamic clock + gating, and 16-bit packing/unpacking. + + Note on RX/TX naming convention: in QAIF, TX refers to the output + (speaker/playback) direction and RX refers to the input (mic/capture) + direction. This applies to both AIF lane directions and CIF slot/mask + properties. + + DMA engine: RDDMA fetches audio from DDR/TCM/LPM into a shared SRAM + latency buffer (SHRAM) and drains it to the interface. WRDMA collects + data from the interface into SHRAM and writes it to memory. Each DMA + owns a private SHRAM region defined by start address and length registers. + Burst sizes of 1/2/4/8/16 beats (64-bit) are supported with up to 4 + outstanding transactions per DMA. Two QSB master ports (QXM0 for TCM, + QXM1 for DDR/LPM) provide the memory interface. + + Resources are partitioned among up to 5 Execution Engines (EEs) via + EE map registers. Each EE owns a set of DMAs, audio interfaces, and + interface groups, and receives its own independent interrupt output. + The interrupt hierarchy has a two-level structure: a summary register + identifies the event class (DMA period, underflow/overflow, error + response, audio interface underflow/overflow, group done, rate detector, + VFR), and per-resource status registers identify the specific channel. + + Interface grouping (bonding) allows up to 6 groups of audio and codec + interfaces to start synchronously and align their DMA period interrupts + within half a frame duration using the RDDMA padding feature. + + Two rate detector blocks measure the frequency of incoming frame sync or + word select signals and generate interrupts on rate change, undetected + rate, or sync timeout. + + Block diagram:: + + System Memory (DDR / LPM / TCM) + +---------------------------------+ + | Circular Buffers (ping-pong) | + +----------+----------+-----------+ + | ^ + 64-bit AXI 64-bit AXI + | | + +----------v----------+-----------+ + | QSB Master Ports | + | +----------+ +----------+ | + | | QXM0 | | QXM1 | | + | +----+-----+ +-----+----+ | + +-------|--------------|----------+ + | | + +-------v--------------v----------+ + | Shared RAM (SHRAM) | + | +------------+ +------------+ | + | | QXM0 Read | | QXM0 Write | | + | | SHRAM | | SHRAM | | + | +------------+ +------------+ | + | +------------+ +------------+ | + | | QXM1 Read | | QXM1 Write | | + | | SHRAM | | SHRAM | | + | +------------+ +------------+ | + +---+--------+--------+-------+---+ + | | | | + +---v--+ +--v---+ +--v---+ +-v----+ + |RDDMA | |RDDMA | |WRDMA | |WRDMA | + | AIF | | CIF | | AIF | | CIF | + |[0..n]| |[0..n]| |[0..n]| |[0..n]| + +--+---+ +--+---+ +--+---+ +-+----+ + | | ^ ^ + | TX | TX | RX | RX + v v | | + +--+--------------------+ +----+----------+ + | Unified Audio Intf | | Codec DMA | + | (AIF 0..12) | | Interface | + | | | (CIF) | + | AUD_INTFa block: | | | + | - Serializer (TX) | | RDDMA: DDR -> | + | - De-serializer (RX) | | internal | + | - Sync gen/detect | | codec | + | - Up to 8 data lanes | | WRDMA: codec | + | - PCM / TDM / MI2S | | -> DDR | + | - Near Pad Logic | | Up to 16 ch | + +--+--------------------+ +----+----------+ + | Lane 0..7 (TX/RX) | Parallel bus + | Bit clk + Frame sync | + Frame sync + v v + +--+--------+ +------+------+ + | External | | Internal | + | Serial | | Digital | + | Peripherals| | Codec | + | (PCM/TDM/ | | (Bolero/ | + | MI2S) | | WCD) | + +-----------+ +-------------+ + +allOf: + - $ref: dai-common.yaml# + +properties: + compatible: + const: qcom,shikra-qaif-cpu + + reg: + maxItems: 1 + + interrupts: + maxItems: 1 + description: + QAIF summary interrupt for this Execution Engine. + + iommus: + maxItems: 1 + + dma-coherent: true + + clocks: + maxItems: 9 + + clock-names: + description: + Core clocks for register access and DMA, followed by one bit + clock per AIF interface. + items: + - const: lpass_config + - const: lpass_core_axim + - const: aud_dma + - const: aud_dma_mem + - const: bus + - const: aif_if0_ibit + - const: aif_if1_ibit + - const: aif_if2_ibit + - const: aif_if3_ibit + + '#sound-dai-cells': + const: 1 + + '#address-cells': + const: 1 + + '#size-cells': + const: 0 + +patternProperties: + '^aif@[0-9a-f]+$': + type: object + description: + QAIF AIF interface child node for PCM, TDM or MI2S configuration. + + allOf: + - $ref: /schemas/sound/tdm-slot.yaml# + + properties: + reg: + maxItems: 1 + description: + DAI ID of the AIF interface (QAIF_MI2S_AIF* or QAIF_TDM_AIF*). + + dai-format: + description: Serial audio interface format (MI2S, TDM or PCM). + enum: [i2s, dsp_a, dsp_b] + + dai-tdm-slot-width: + enum: [8, 16, 24, 32] + + dai-tdm-slot-num: + minimum: 1 + maximum: 32 + + dai-tdm-slot-rx-mask: + minItems: 1 + maxItems: 32 + + dai-tdm-slot-tx-mask: + minItems: 1 + maxItems: 32 + + qcom,qaif-aif-lane-map: + $ref: /schemas/types.yaml#/definitions/uint32-array + description: + Per-lane direction map, one entry per lane starting from lane 0. + Use 0 for TX (output/speaker) and 1 for RX (input/mic). + minItems: 1 + maxItems: 8 + items: + enum: [0, 1] + + required: + - reg + - dai-format + - qcom,qaif-aif-lane-map + + if: + properties: + dai-format: + enum: [dsp_a, dsp_b] + then: + required: + - dai-tdm-slot-width + - dai-tdm-slot-num + - dai-tdm-slot-rx-mask + - dai-tdm-slot-tx-mask + + unevaluatedProperties: false + +required: + - compatible + - reg + - interrupts + - iommus + - clocks + - clock-names + - '#sound-dai-cells' + - '#address-cells' + - '#size-cells' + +unevaluatedProperties: false + +examples: + - | + #include + soc { + #address-cells = <2>;
