STRUCT SPMI_VOLTAGE_RANGE(9)

💖 struct spmi_voltage_range(9) 💖

okay so bestie, welcome to the Kernel API Manual — this page is your little group chat for struct spmi_voltage_range(9), and it is literally giving regulator set point voltage mapping. no cap, every field matters 💅

✨ NAME ✨

struct spmi_voltage_range — regulator set point voltage mapping description.

🦋 SYNOPSIS 🦋

       struct spmi_voltage_range {
           int min_uV;
           int max_uV;
           int step_uV;
           int set_point_min_uV;
           int set_point_max_uV;
           unsigned n_voltages;
           u8 range_sel;
        };

💅 Members 💅

okay, here is the cast — every member is a main character:

• min_uV — Minimum programmable output voltage resulting from set point register value 0x00.
• max_uV — Maximum programmable output voltage.
• step_uV — Output voltage increase resulting from the set point register value increasing by 1.
• set_point_min_uV — Minimum allowed voltage.
• set_point_max_uV — Maximum allowed voltage. This may be tweaked in order to pick which range should be used in the case of overlapping set points.
• n_voltages — Number of preferred voltage set points present in this range.
• range_sel — Voltage range register value corresponding to this range.

🌸 Description 🌸

okay so the following relationships must be true for the values used in this struct — like, non-negotiable bestie:

(max_uV - min_uV) % step_uV == 0
(set_point_min_uV - min_uV) % step_uV == 0*
(set_point_max_uV - min_uV) % step_uV == 0*
n_voltages = (set_point_max_uV - set_point_min_uV) / step_uV + 1

*Note, set_point_min_uV == set_point_max_uV == 0 is allowed in order to specify that the voltage range has meaning, but is not preferred.
