STRUCT MTK_SPI_COMPATIBLE(9)

💫 struct mtk_spi_compatible(9) 💫

okay so bestie, welcome to the Kernel API Manual page for struct mtk_spi_compatible — yes that whole mouthful — and no, we are not skipping a single field, because every one of these bools is doing something 🫶

---

✨ NAME ✨

struct mtk_spi_compatible — the device data structure. that's it, that's the vibe. it's the little bundle of "which quirks does this SPI controller have" flags. lowkey iconic.

---

🌸 SYNOPSIS 🌸

here's the whole thing, character for character, no cap:

struct mtk_spi_compatible {
    bool need_pad_sel;
    bool must_tx;
    bool enhance_timing;
    bool dma_ext;
    bool no_need_unprepare;
    bool ipm_design;
 };

six bools. six little switches. each one tells the driver how this particular controller wants to be handled 💅

---

🦋 Members 🦋

okay so let's go through them one by one, bestie, no skipping:

• need_pad_sel — turns on pad (pins) selection in the SPI controller. like, the controller gets to pick which pads it's actually talking through. pins matters, periodt ✨
• must_tx — means you must explicitly send dummy TX bytes in order to do an RX only transfer. no sneaky receive-only shortcut here, the hardware wants its lil fake transmissions first 🙈
• enhance_timing — enables adjusting the cfg register to enhance time accuracy. yes bestie, we're fiddling with the config register for better timing precision 🔥
• dma_ext — DMA address extension is supported. bigger addresses, more reach, main character energy 👑
• no_need_unprepare — says don't unprepare the SPI clk during runtime. like leave the clock alone, it's fine, it's thriving 💀
• ipm_design — adjust/extend registers to support IPM design IP features. register glow-up, basically 🎀

fr fr, this struct is just a compatibility checklist in disguise. tiny, but it's giving essential 💖
