regmap_multi_reg_read(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

regmap_multi_reg_read — read multiple non-sequential registers from the device, bestie ✨

(Also, hi, this is the regmap_multi_reg_read(9) page from the Kernel API Manual — welcome to the group chat 🫶)

🌸 SYNOPSIS 🌸

int regmap_multi_reg_read (struct regmap *map , const unsigned int *regs
, void *val , size_t val_count );

🎀 ARGUMENTS 🎀

  • map — the register map you're reading from, your main character 🗺️✨
  • regs — an array of registers to read from, like a little guest list 💌
  • val — pointer to store the read value, in the native register size for the device (so, device-dependent sizing, don't come for me) 💾
  • val_count — how many registers you're reading, i.e. the headcount 🔢

🦋 DESCRIPTION 🦋

okay so. A value of zero will be returned on success 😌🎉, and a negative errno will be returned in error cases 😭💀.

That's it, that's the whole vibe. No cap. 💅

Heads up bestie: non-sequential means the registers do NOT have to be next to each other in the address space — that's the whole point of this call 🧚‍♀️
