STRUCT MCHP_SPDIFRX_DEV(9)

💜 NAME

struct mchp_spdifrx_dev — bestie, this is the MCHP SPDIFRX device data structure, like, the whole vibe container for one SPDIFRX device ✨

(also hi, you're reading the Kernel API Manual, section 9, and this page is literally all about that one struct, so let's go 🎀)

🌸 SYNOPSIS

struct mchp_spdifrx_dev {
    struct snd_dmaengine_dai_dma_data       capture;
    struct mchp_spdifrx_mixer_control       control;
    struct mutex                            mlock;
    struct device                           *dev;
    struct regmap                           *regmap;
    struct clk                              *pclk;
    struct clk                              *gclk;
    unsigned int                            trigger_enabled;
 };

no cap, that's the whole thing 👑 copy it exactly, don't be out here renaming fields, iykyk 💅

🦋 Members

okay so, field by field, let's do a vibe check on every single one 🫶

• capture — the DAI DMA configuration data. it's giving "how do we actually move the audio bytes" energy 🎀
• control — the mixer controls. yeah. the knobs. the sliders. iconic 🌸
• mlock — a mutex whose whole job is to protect concurrency between the configuration APIs and the control APIs. it's the bouncer at the club, keeping those two from colliding 😭
• dev — a struct device. literally just the device. main character energy fr 💀
• regmap — the regmap for this device. register access, slay 🔥
• pclk — the peripheral clock ⏰
• gclk — the generic clock ⏰✨
• trigger_enabled — true if it was enabled through the trigger ops. so like, a little boolean telling you if the trigger path turned it on 💖

ngl bestie, mlock is highkey the one to respect here — that's your concurrency guard, don't be out here touching config and control at the same time without it 🙈

and that's the page!! 🎀 this whole thing came from the source tree over at ./sound/soc/atmel, dated October 2026, and it's the struct mchp_spdifrx_dev(9) page from the Kernel API Manual — mwah, go forth and read structs, bestie 🫶✨💅
