📦 version 7.3.1, in nixpkgs unstable

💅 ca8210_config_extern_clk(9) — from the Kernel API Manual, bestie 🎀

okay so real talk, this one lives in the Kernel API Manual and it's literally the little function that turns the ca8210's external clock on and off ✨ it's giving "tiny but crucial" and honestly? we're obsessed.

🌸 NAME 🌸

ca8210_config_extern_clk — Configure the external clock provided by the ca8210 🕰️

✨ SYNOPSIS ✨

int ca8210_config_extern_clk (struct ca8210_platform_data *pdata ,
struct spi_device *spi , bool on );

🫶 ARGUMENTS 🫶

  • pdata — a pointer to ca8210_platform_data that's holding all the clock parameters 💖
  • spi — a pointer to the target ca8210 spi device 🦋
  • on — true to turn the clock on, false to turn it off. that's it. that's the whole vibe check ⭐

💅 DESCRIPTION 💅

So the external clock gets configured using a frequency and an output pin, and both of those come straight outta the platform data. no cap, that's genuinely the whole thing — it reads pdata, it does the clock thing, done. 🔥

🔥 RETURN 🔥

0 or a linux error code 😭 (so like, check it, bestie — 0 is the slay outcome, anything else means something went sideways)
