ok so first thing's first, bestie β€” this is a page straight out of the Kernel API Manual, and yes the title is literally truncated with ... in the middle. that's not me being lazy, that's just how it's printed, iykyk 🫢


✨ NAME ✨

gpmc_omap_onenand_set_timings β€” set optimized sync timings. that's the whole vibe. it optimizes, it syncs, it sets timings. slay πŸ’«


🌸 SYNOPSIS 🌸

int gpmc_omap_onenand_set_timings (struct device *dev , int cs , int
freq , int latency , struct gpmc_onenand_info *info );

like, five arguments, returns an int, no notes. periodt. πŸŽ€


πŸ¦‹ ARGUMENTS πŸ¦‹

  • dev β€” ok so this one is literally marked -- undescribed -- in the source. so... nobody described it. it's giving mystery. main character energy but with zero backstory πŸ™ˆ the docs genuinely say nothing about it, so i'm not gonna make something up. undescribed, and that's canon.
  • cs β€” the Chip Select Region. this is the region we're messing with πŸ—ΊοΈ
  • freq β€” the Chip frequency. how fast the chip is chugging along ⚑
  • latency β€” the Burst latency cycle count. how many cycles of delay in the burst, no cap 🌈
  • info β€” a Structure describing parameters used. it's a struct gpmc_onenand_info *, it holds the parameters, it's the moment 🧚

πŸ’– DESCRIPTION πŸ’–

so what does it actually do? it Sets optimized timings for the cs region based on freq and latency. that's the whole job. you hand it a chip select region, a frequency and a latency, and it goes off and figures out the optimized timings for that region. literally doing the math so you don't have to 😭

and then β€” because it's not done being generous β€” it Updates the info structure based on the GPMC settings. so the struct you passed in comes back reflecting whatever the GPMC settings ended up being. so you get optimized timings and a freshly updated info struct. ate and left no crumbs πŸ‘‘

ngl, that's it. no warnings, no gotchas, no exit status lore on this page. just vibes and timings πŸ’€
