💖 sa1111_pll_clock(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, the actual manual, we're doing this, and this little function is the main character today 🎀

✨ NAME ✨

sa1111_pll_clock — returns the current PLL clock frequency, no cap 💅

🌸 SYNOPSIS 🌸

unsigned int sa1111_pll_clock (struct sa1111_dev *sadev );

🦋 ARGUMENTS 🦋

• sadev — the SA1111 function block, literally the thing you're passing in 🫶

⭐ DESCRIPTION ⭐

so first thing, bestie, there's a BUG note right here and we're not gonna pretend it isn't: we should be looking at SKCR. that's the whole note. we should look at SKCR. we are not looking at SKCR. 🙈

also — and this is the part where we're just being honest — we blindly believe that the chip is being fed with the 3.6864MHz clock. blindly. believe. no vibe check, no verification, just trust ✨

and then it returns the PLL clock in Hz 💖
