And this driver will be used in StarFive's VisionFive 2 board. In 6.4, the QSPI_AHB and QSPI_APB clocks changed from the default ON state to the default OFF state, so these clocks need to be enabled in the driver.At the same time, dts patch is added to this series. Changes v5->v4: - Rebased to v6.4rc4. - Dropped the Reported-by tags. Changes v4->v5: - Rebased to v6.5rc2. - Changed the way to initialization the clocks. - Changed the layout for the SPI flash. Changes v3->v4: - Added minItems for clocks. - Added clock names property. - Fixed formatting issues. Changes v2->v3: - Rebased to v6.4rc6. - Renamed the clock names. - Changed the variable definition type. Changes v1->v2: - Renamed the clock names. - Specified a different array of clocks. - Used clk_bulk_ APIs. The patch series is based on v6.5rc4.
