gpio_generic_write_reg(9)

🎀 NAME 🎀

okay so bestie, this is gpio_generic_write_reg(9) from the Kernel API Manual, and highkey it does exactly one iconic thing: write a register using the underlying callback. the way that it just writes and dips? obsessed. no cap. ✨

🦋 SYNOPSIS 🦋

the signature, exactly as written, because we do not mess with the source:

void gpio_generic_write_reg (struct gpio_generic_chip *chip , void
       __iomem *reg , unsigned long val );

it returns void, so there's literally nothing coming back — just the write happening and you moving on. periodt 💅

🌸 ARGUMENTS 🌸

• chip — the generic GPIO chip to use. like, the chip you're working through, main character energy.
• reg — the register to write to. this is the spot getting the new value.
• val — the new value to write. the value sliding into reg, no cap.

the full reference crew, everyone accounted for:

• Kernel file ./include/linux/gpio/generic.h struct
• gpio_generic_chip_config(9)
• struct gpio_generic_chip(9)
• gpio_generic_chip_set(9)
• gpio_generic_read_reg(9)

iykyk — that's the SEE ALSO lineup, bestie. slay. 💖
