🎀 NAME 🎀

fbtft_verify_gpios — the generic verify_gpios() function. that's literally it, that's the whole vibe check 👑

🌸 SYNOPSIS 🌸

int fbtft_verify_gpios (struct fbtft_par *par );

🦋 ARGUMENTS 🦋

• par — the driver data 🫶 that's the one and only thing you hand it.

⭐ DESCRIPTION ⭐

so what does it actually do. it uses spi, pdev and buswidth to figure out which GPIOs are needed. that's it. that's the function. no cap 🔥

like, it's literally the generic verify_gpios() — hence the name, iykyk — and its whole personality is deducing the GPIO situation from those three things.

🌈 RETURN 🌈

• 0 if it worked, slay 💅
• a negative number if something went wrong 😭
