💖 NAME 💖

okay bestie, welcome to the zynqmp_qspi_write_op(9) page from the Kernel API Manual ✨ this one is a function that sets up the GENFIFO entries, the TX FIFO, and fills the TX FIFO with as many bytes as possible. no cap, it's giving “get the FIFO ready and keep it fed.” 🎀

🌸 SYNOPSIS 🌸

void zynqmp_qspi_write_op (struct zynqmp_qspi *xqspi , u8 tx_nbits , u32 genfifoentry );

🦋 ARGUMENTS 🦋

• xqspi — pointer to the GQSPI instance 💜 that's the one we're working with, bestie.
• tx_nbits — the transfer buswidth 🌈 literally the buswidth for the transfer.
• genfifoentry — a variable in which the GENFIFO mask is returned to the calling function 🫶 it comes back out through this lil parameter, periodt.
