STRUCT QUSB2_PHY(9)

💅 struct qusb2_phy(9) — from the Kernel API Manual, bestie

okay so picture this: it's a whole struct in the kernel, right, and it's the one holding all the qusb2 phy attributes. literally its entire job. iconic of it, honestly 🫶

✨ NAME ✨

struct qusb2_phy — the structure that holds all the qusb2 phy attributes 💖

🌸 SYNOPSIS 🌸

struct qusb2_phy {
    struct phy *phy;
    void __iomem *base;
    struct clk *cfg_ahb_clk;
    struct clk *ref_clk;
    struct clk *iface_clk;
    struct reset_control *phy_reset;
    struct regulator_bulk_data vregs[QUSB2_NUM_VREGS];
    struct regmap *tcsr;
    struct nvmem_cell *cell;
    struct override_params overrides;
    const struct qusb2_phy_cfg *cfg;
    bool has_se_clk_scheme;
    bool phy_initialized;
    enum phy_mode mode;
 };

like, look at her. every single field accounted for. no notes 👑

🎀 Members 🎀

okay bestie let's go field by field, i promise it's not that deep:

• phy — the generic phy. the main character of the whole thing fr.
• base — iomapped memory space for qubs2 phy (yes that's the spelling in the source, don't come for me 💀).
• cfg_ahb_clk — the AHB2PHY interface clock ⏰
• ref_clk — the phy reference clock, the vibe-setter of clocks
• iface_clk — the phy interface clock
• phy_reset — the phy reset control, hold my hand while i reset you energy
• vregs — regulator supplies bulk data — it's literally struct regulator_bulk_data vregs[QUSB2_NUM_VREGS], an entire array of them, slay
• tcsr — the TCSR syscon register map 🗺️
• cell — the nvmem cell containing the phy tuning value, lowkey important
• overrides — pointer to the structure for all the overriding tuning params — every last one of them
• cfg — the phy config data
• has_se_clk_scheme — a bool that indicates if the PHY has the single-ended ref clock scheme ✨
• phy_initialized — a bool that indicates if the PHY has been initialized — the "have we done this already" flag
• mode — the current PHY mode, an enum phy_mode, living its truth
