It seems you've > missed these two though. The QSPI module of JH7110 supported by Cadence, requires three clocks (qspi_ahb, qspi_apb and qspi_ref), but the Cadence QSPI driver only supports one clock. As the StarFive QSPI support patches [1] had been accepted, I kept these two flags here.

It's ok to move these functions to clk-starfive-jh7110-sys.c. By the way, could I still keep the declaration in clk-starfive-jh71x0.h?

As the StarFive QSPI support > patches [1] had been accepted, I kept these two flags here. The QSPI driver obviously needs to be fixed so it doesn't depend on the bootloader leaving the clocks enabled.
