STRUCT SAMSUNG_SPDIF_INFO(9)

✨ struct samsung_spdif_info(9) ✨

okay so bestie, buckle up — this is the Kernel API Manual page for struct samsung_spdif_info, and honestly? it's giving "let me introduce you to the whole S/PDIF squad" 💅 this is the lil info struct that holds everything the Samsung S/PDIF Controller needs to know about itself. no cap.

🌸 NAME 🌸

struct samsung_spdif_info — Samsung S/PDIF Controller information 💖

like, the whole personality of the controller, packaged in one struct. iconic.

🎀 SYNOPSIS 🎀

struct samsung_spdif_info {
    spinlock_t lock;
    struct device   *dev;
    void __iomem    *regs;
    unsigned long   clk_rate;
    struct clk      *pclk;
    struct clk      *sclk;
    u32 saved_clkcon;
    u32 saved_con;
    u32 saved_cstas;
    struct snd_dmaengine_dai_dma_data *dma_playback;
 };

look at her. ten fields. main character energy fr fr 🫶

here's the group chat roster, one by one:

• lock — the spin lock for S/PDIF. she's the bouncer at the door keeping everybody from barging in at once 🔒
• dev — the parent device, passed to use from the probe. yeah, the one that showed up and said "hi i'm your parent now" 💀
• regs — pointer to the device register block. this is where the actual hardware lore lives ✨
• clk_rate — current clock rate for calcurate ratio. (yes. that is the spelling in the source. we're keeping it, we don't edit the ancestors 💅) number goes brrr so the ratio math works.
• pclk — the peri-clock pointer for spdif master operation. she's the one running the master-side situation 👑
• sclk — the source clock pointer for making sync signals. sync signals don't make themselves, bestie 🌈
• saved_clkcon — backup clkcon reg. in suspend. nap-time snapshot 😴
• saved_con — backup con reg. in suspend. another nap-time snapshot 🍓
• saved_cstas — backup cstas reg. in suspend. third nap-time snapshot, we stan a consistent saver 🙈
• dma_playback — DMA information for playback channel. this is how the audio actually gets out, lowkey the most important one 🔥

ok that's the whole page!! every field, every description, nothing skipped, nothing invented. vibe check: passed ✅

mwah 💖 thanks for reading bestie — this one's from ./sound/soc/samsung, dated October 2026, and it lives at struct samsung_spdif_info(9) in the Kernel API Manual. periodt. 💅
