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@xxxxxxxxxxx/
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@xxxxxxxxxxx/
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@xxxxxxxxxxx/
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.
