[v13,0/2] spi: loongson: add bus driver for the loongson spi

  Loongson platform support spi hardware controller and this series patch
was to add spi driver and binding support.

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:

		2. Add "#include <linux/io.h>" 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 <dt-bindings/clock/loongson,ls2k-clk.h>" in
		   yaml file.
Change in v7:
		1. Remove the "loongson,ls7a-spi" and change yaml file name as

[1/2] spi: dt-bindings: add loongson spi
      commit: b350e6c6297aaa2533da23a21398751eeeecc101
[2/2] spi: loongson: add bus driver for the loongson spi controller
      commit: 6c7a864007b66e60a3f64858a9555efed408b048

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
