gpmc_calc_divider(9)

💅 gpmc_calc_divider ✨

okay so bestie, we're deep in the Kernel API Manual and this page is all about gpmc_calc_divider — the function that does the GPMC_FCLK divider math for the sync_clk GPMC_CLK period. no cap, that's the whole vibe 💖

🌸 NAME 🌸

gpmc_calc_divider — calculate GPMC_FCLK divider for sync_clk GPMC_CLK period.

✨ SYNOPSIS ✨

int gpmc_calc_divider (unsigned int sync_clk );

🎀 ARGUMENTS 🎀

• sync_clk — GPMC_CLK period in ps. literally the period value you hand over, in picoseconds 🫶

💅 RETURN 💅

Returns at least 1 if GPMC_FCLK can be divided to GPMC_CLK. Else, returns -1.

so if the divide works out you get >= 1, and if it doesn't, bestie it's -1 😭
