Annotated Snippet

Mediatek ALSA BT SCO CVSD/MSBC Driver

Required properties:
- compatible = "mediatek,mtk-btcvsd-snd";
- reg: register location and size of PKV and SRAM_BANK2
- interrupts: should contain BTSCO interrupt
- mediatek,infracfg: the phandles of INFRASYS
- mediatek,offset: Array contains of register offset and mask
    infra_misc_offset,
    infra_conn_bt_cvsd_mask,
    cvsd_mcu_read_offset,
    cvsd_mcu_write_offset,
    cvsd_packet_indicator_offset

Example:

	mtk-btcvsd-snd@18000000 {
		compatible = "mediatek,mtk-btcvsd-snd";
		reg=<0 0x18000000 0 0x1000>,
		    <0 0x18080000 0 0x8000>;
		interrupts = <GIC_SPI 286 IRQ_TYPE_LEVEL_LOW>;
		mediatek,infracfg = <&infrasys>;
		mediatek,offset = <0xf00 0x800 0xfd0 0xfd4 0xfd8>;
	};

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
