STRUCT RPMH_VREG_HW_DATA(9)

💖 struct rpmh_vreg_hw_data(9) 💖

Welcome to the Kernel API Manual, bestie ✨ Today’s main character is struct rpmh_vreg_hw_data — the RPMh regulator hardware configurations blueprint. It’s giving “how this regulator is built,” and we’re obsessed.

✨ NAME ✨

struct rpmh_vreg_hw_data — RPMh regulator hardware configurations. That’s the whole vibe, no cap 💅

🫶 SYNOPSIS 🫶

       struct rpmh_vreg_hw_data {
           enum rpmh_regulator_type                regulator_type;
           const struct regulator_ops              *ops;
           const struct linear_range               *voltage_ranges;
           int n_linear_ranges;
           int n_voltages;
           int hpm_min_load_uA;
           int pmic_bypass_mode;
           const int                               *pmic_mode_map;
           unsigned int                          (*of_map_mode)(unsigned int
       mode);
        };

🦋 Members 🦋

• regulator_type — the RPMh accelerator type used to manage this regulator. It’s the “who’s in charge” field, lowkey iconic.
• ops — pointer to the regulator ops callback structure. Callback HQ, basically 🫶
• voltage_ranges — the possible ranges of voltages supported by this PMIC regulator type. Voltage menu unlocked ✨
• n_linear_ranges — number of entries in voltage_ranges. Literally the count, bestie.
• n_voltages — the number of unique voltage set points defined by voltage_ranges. So many set points, so little time 💀
• hpm_min_load_uA — minimum load current in microamps that requires high power mode (HPM) operation. This is used for LDO hardware type regulators only — LDOs only, don’t generalize 🙈
• pmic_bypass_mode — the PMIC bypass mode value. It’s the bypass mode value, periodt.
• pmic_mode_map — array indexed by regulator framework mode containing PMIC hardware modes. It must be large enough to index all framework modes supported by this regulator hardware type — no tiny arrays, bestie 💀
• of_map_mode — maps an RPMH_REGULATOR_MODE_* mode value defined in device tree to a regulator framework mode. Device-tree-to-framework translator, slay 🌈
