  4. arm64: spi: Phytium-qspi: Add support for Phytium QSPI controller 

    This patch adds a new driver for Phytium QuadSPI (QSPI) controller,
which is used to access NOR Flash memory slaves. The driver implements
spi-mem framework and does not support generic SPI operations.

  5. arm64: spi: Phytium: Fix controller unregister order 

    The driver used devm_spi_register_controller() on bind. Therefore,
__device_release_driver() first invokes phytium_spi_remove_host()
before unregistering the SPI controller via devres_release_all() when
unbinding.

Since phytium_spi_remove_host() shuts down the chip, rendering the SPI
bus inaccessible even through the SPI controller is still registered.
When the SPI controller is subsequently unregistered, it unbinds all
its slave devices. Because their drivers cannot access the SPI bus,
the slave devices may be left in an improper state.

  6. arm64: spi: phytium: Extract right pointer from driver_data in PM ops 

    Since the platform driver wraps the core phytium_spi into
phytium_spi_clk struct to include a platform clock, the pointer
extract from driver_data should also be 'struct phytium_spi_clk *'.

  7. arm64: spi: Phytium: Fix r/w sck_sel_mask 3 to 7 in SPI/QSPI driver 

    The mask of sck_sel should be 0x7 instead of 0x3, otherwise the split
is set differently than expected.
