okay so bestie, welcome to the Kernel API Manual entry for zynqmp_qspi_config_op β€” the little helper that configures the QSPI controller for a specified transfer. it’s giving β€œsetup era” energy, no cap. πŸŽ€


πŸ¦‹ NAME πŸ¦‹

zynqmp_qspi_config_op β€” configure QSPI controller for specified transfer. πŸ’–


✨ SYNOPSIS ✨

       int zynqmp_qspi_config_op (struct zynqmp_qspi *xqspi , const struct
       spi_mem_op *op );

🫢 ARGUMENTS 🫢

  • xqspi β€” pointer to the zynqmp_qspi structure. literally the controller’s main-character struct. πŸ‘‘
  • op β€” the memory operation to execute. the actual move we’re setting up. 🌸

πŸ’… DESCRIPTION πŸ’…

This function sets the operational mode of the QSPI controller for the next QSPI transfer, and it sets the requested clock frequency. that’s the whole vibe: mode check + clock check, slay. ✨


🌈 RETURN 🌈

Always 0. yes bestie, always. no dramatic exit codes here, periodt. πŸ’€


πŸ”₯ NOTE πŸ”₯

If the requested frequency is not an exact match with what can be obtained using the pre-scalar value, the driver sets the clock frequency which is lower than the requested frequency (maximum lower) for the transfer.
If the requested frequency is higher or lower than that is supported by the QSPI controller the driver will set the highest or lowest frequency supported by controller.
