[v5,0/4] Devicetree support for Loongson-1 clock

Message

Keguang Zhang March 21, 2023, 11:18 a.m. UTC

Removes the old Loongson-1 clock driver and related code
mainly because of no DT support and outdated implementation.

Then, re-implement it to solve the above issues,
along with the devicetree binding document.

Changelog
V4 -> V5: Include the necessary header files
          Add error handling for ls1x_clk_init()
          Remove MODULE_AUTHOR and MODULE_DESCRIPTION
          Some fixes and cleanups
V3 -> V4: Fix the build error of missing linux/module.h
          Add Reviewed-by tag from Krzysztof Kozlowski
V2 -> V3: Add 'reg' property into the 'required' field
          Delete the unnecessary property 'clock-names'
          Use the same license as binding document for the header file.
          Add MODULE_AUTHOR and MODULE_DESCRIPTION info
          Add patch "MIPS: loongson32: Update the clock initialization" into this series
	  Add Acked-by tag from Stephen Boyd and Thomas Bogendoerfer
V1 -> V2: Change to one clock controller (suggested by Krzysztof Kozlowski)
          Add clock-related dt-binding header file
          Fix the warning of dt_binding_check
          Split the driver removal to a separate patch
          Implement one clock controller instead of single clocks
          (suggested by Krzysztof Kozlowski)
