ASoC: mediatek: add initial MT6572 + MT6323 PMIC audio (PAP5500 DUO + Lenovo A369i) by gabin8 · Pull Request #9 · mt6572-mainline/linux

gabin8 · 2026-06-02T21:40:44Z

Audio support for the MT6572 AFE + MT6323 PMIC codec, verified on the Prestigio PAP5500 DUO and the Lenovo A369i.

What it brings up

MT6572 AFE DL1 playback front-end (HW-IRQ driven, streams from the on-chip SRAM).
MT6323 PMIC analog codec — DAC, headphone output and volume controls, over the MT6397 PMIC-wrapper regmap.
Speaker output, board-dependent:
- PAP5500 DUO — external Yamaha YDA145 amplifier modelled as a generic simple-audio-amplifier aux device, fed from the headphone output.
- Lenovo A369i — the MT6323's internal class-D amplifier (SPK_CON), driven directly on the SPK_P/SPK_N pins, with an analog "Speaker Volume" control.
Headphone-jack detection that auto-routes speaker ↔ headphones (PAP5500 DUO: GPIO142/EINT7; A369i: GPIO136/EINT2).

Tested on hardware

PAP5500 DUO — playback on speaker + headphones (aplay), volume (AFE digital gain), jack insert/removal auto-switching.
Lenovo A369i — playback on the internal class-D speaker + headphones, the analog "Speaker Volume" control, jack auto-switching.

Structure

The original MT6572 AFE + MT6323 codec + PAP5500 DUO enablement, plus three commits for the Lenovo A369i: internal class-D speaker support in the codec, the board DTS + jack EINT pin, and the README status.

drop sub-node and syscon wording. dt-bindings should describe hardware, not the kernel stuff.

+  iram:


can this be a reg of the AFE?

SRAM is a distinct block at 0x11141000. AFE control window is 0x11140000–0x11140fff, so it's a standard mmio-sram node handed to the DL1.
Making it a reg of the AFE is not correct: AFE has no reg of its own (it maps the parent audsys window).
I can rename the property iram -> mediatek,sram if the name is the concern.

i think iram is fine, it's used in few kernel DTs

i feel this should be separate. AFE is AFE, codec is codec, and the audio is the glue. i found this for mt8186:

sound: mt8186-sound { compatible = "mediatek,mt8186-mt6366-da7219-max98357-sound"; model = "mt8186_da7219_m98357"; pinctrl-names = "aud_clk_mosi_off", "aud_clk_mosi_on"; pinctrl-0 = <&aud_clk_mosi_off>; pinctrl-1 = <&aud_clk_mosi_on>; mediatek,platform = <&afe>; audio-routing = "Headphones", "HPL", "Headphones", "HPR", "MIC", "Headset Mic", "Speakers", "Speaker", "HDMI1", "TX"; hs-playback-dai-link { link-name = "I2S0"; dai-format = "i2s"; mediatek,clk-provider = "cpu"; codec { sound-dai = <&da7219>; }; }; hs-capture-dai-link { link-name = "I2S1"; dai-format = "i2s"; mediatek,clk-provider = "cpu"; codec { sound-dai = <&da7219>; }; }; spk-dp-playback-dai-link { link-name = "I2S3"; dai-format = "i2s"; mediatek,clk-provider = "cpu"; codec { sound-dai = <&anx_bridge_dp>, <&max98357a>; }; }; };

Checked the MT6572W functional spec: the MT6323 link isn't a board I2S bus - it's the AFE's output-only I2S (AFE_I2S_CON1) + ADDA downlink SRC out the fixed PMIC pins (AUD_*_MOSI/ADC_DAT_MISO), i.e. the exact equivalent of mt8183's "ADDA" back-end to mt6358.
So I'll match mt8183: AFE platform-only, a separate mt6572-mt6323 machine driver, the codec as a hardcoded ADDA-style back-end in C, and a minimal sound node

DEAD means there's no such feature, TBD means it exists on other devices but not working yet. partial means something is working but not really usable (this one you want), OK means no major issues

move into irq handler or drop

+	status &= AFE_IRQ_MCU_STATUS_MASK;
+	if (!status) {
+		regmap_write(afe->regmap, AFE_IRQ_MCU_CLR, AFE_IRQ_MCU_CLR_NOSTATUS);


is write of the whole AFE_IRQ_MCU_CLR_NOSTATUS required here? can it be just regmap_write(afe->regmap, AFE_IRQ_MCU_CLR, status);?
