Change in v2: 1. This [PATCH v2 1/2] dt-bindings patch need depend on clk patch: https:// lore.kernel.org/all/20230307115022.12846-1-zhuyinbo@loongson.cn/ 2. Remove the clock-names in spi yaml file. 3. Add "loongson,ls7a-spi" compatible in spi yaml file. 4. Add an || COMPILE_TEST and drop && PCI then add some CONFIG_PCI macro to limit some pci code. 5. Make the spi driver top code comment block that use C++ style. 6. Drop spi->max_speed_hz. 7. Add a spin_lock for loongson_spi_setup. 8. Add a timeout and cpu_relax() in loongson_spi_write_read_8bit. 9. Add spi_transfer_one and drop transfer and rework entire spi driver that include some necessary changes. 10. Use module_init replace subsys_initcall. 11. About PM interface that I don't find any issue so I don't add any changes. Change in v3: 1. This [PATCH v3 1/2] dt-bindings patch need depend on clk patch: https:// lore.kernel.org/all/20230323025229.2971-1-zhuyinbo@loongson.cn/ 2. Drop the unused blank line in loongson,ls-spi.yaml file. 3. Replace clock minItems with clock maxItems in yaml file. 4. Separate spi driver into platform module, pci module and core module. 5. Replace DIV_ROUND_UP with DIV_ROUND_UP_ULL to fix compile error "undefined reference to `__aeabi_uldivmod'" and "__udivdi3 undefined" that reported by test robot. 6. Remove the spin lock. 7. Clear the loongson_spi->hz and loongson_spi->mode in setup to fixup the issue that multiple spi device transfer that maybe cause spi was be misconfigured. Change in v4: 1. This [PATCH v4 1/2] dt-bindings patch need depend on clk patch: https:// lore.kernel.org/all/20230323025229.2971-1-zhuyinbo@loongson.cn/ 2. Add "#include " in spi-loongson-core.c for fix the compile issue which devm_ioremap no declaration. 3. Add "EXPORT_SYMBOL_GPL(loongson_spi_dev_pm_ops)" in spi-loongson-core.c for fix the compile issue which loongson_spi_dev_pm_ops undefined. Change in v5: 1. Get rid of the clock patch's dependency and open-code the clock IDs. 2. Fixup checkpatch issue that by installed ply and gitpython package locally, but this series of patch's code doesn't have any change. Change in v6: 1. Remove the "#include " in yaml file. Change in v7: 1. Remove the "loongson,ls7a-spi" and change yaml file name as "loongson,ls2k-spi.yaml". 2. Use module_pci_driver and module_platform_driver to replace module_init and module_exit. 3. Drop ".owner = THIS_MODULE" in spi platform driver. 4. Add devm_spi_alloc_master devm_spi_register_master to simplify code. 5. Add pci_disable_device() in loongson_spi_pci_unregister. Change in v8: 1. Add reviewed-by information for spi bindings patch. 2. Fixup the uncorrect spi yaml file path in MAINTAINERS file. 3. Add spi_master_suspend and spi_master_resume in spi pm function. Change in v9: 1. Make spi_master_suspend go first in pm suspend. Change in v10: 1. Fix the compile issue about of_node_get and of_get_property no declaration. 2. set config SPI_LOONGSON_CORE invisible. 3. Captial "spi" in commit log and Kconfig file. 4. Write header files in alphabetical order. 5. Use clamp_val, GENMASK() and BIT() in spi clock setting. 6. Optimize clock and mode setting code. 7. Use readb_poll_timeout in loongson_spi_write_read_8bit. 8. Remove some useless dmesg print. 9. Use device_set_node replace of_node_get. 10. Use dev_err_probe in code. 11. Use devm_clk_get_optional replace devm_clk_get. 12. Remove SPI_NO_CS for drop 2k500 non common type spi. 13. Use pcim_enable_device() and pcim_iomap_regions() in spi pci driver. 14. Passing the remapped address in loongson_spi_init_master. 15. Remove the useless goto flag "err_out". 16. Use pci vendor id in pci_ids.h. 17. Use devm_platform_ioremap_resource in spi platform driver. 18. Remove the useless item in pci_device_id. 19. Remove the inned comma in of_device_id. 20. Add some headfile in spi_loongson.h. 21. Remove the useless extern for loongson_spi_init_master in spi_loongson.h.
