The Nuvoton Arbel NPCM8XX SoC is a fourth-generation BMC. The NPCM8XX computing subsystem comprises a quadcore ARM Cortex A35 ARM-V8 architecture. This patchset adds minimal architecture and drivers such as: Clocksource, Clock, Reset, and WD. Some of the Arbel NPCM8XX peripherals are based on Poleg NPCM7XX. This patchset was tested on the Arbel NPCM8XX evaluation board. Addressed comments from: - Arnd Bergmann: https://www.spinics.net/lists/arm-kernel/msg991125.html - Christophe JAILLET : https://www.spinics.net/lists/kernel/msg4410204.html Changes since version 5: - NPCM8XX clock driver - Remove refclk if devm_of_clk_add_hw_provider function failed. - NPCM8XX clock source driver - Remove NPCM8XX TIMER_OF_DECLARE support, using the same as NPCM7XX. Changes since version 4: - NPCM8XX clock driver - Use the same quote in the dt-binding file. Changes since version 3: - NPCM8XX clock driver - Rename NPCM8xx clock dt-binding header file. - Remove unused structures. - Improve Handling the clocks registration. - NPCM reset driver - Add ref phandle to dt-binding. Changes since version 2: - Remove NPCM8xx WDT compatible patch. - Remove NPCM8xx UART compatible patch. - NPCM8XX clock driver - Add debug new line. - Add 25M fixed rate clock. - Remove unused clocks and clock name from dt-binding. - NPCM reset driver - Revert to npcm7xx dt-binding. - Skip dt binding quotes. - Adding DTS backward compatibility. - Remove NPCM8xx binding include file. - Warp commit message. - NPCM8XX device tree: - Remove unused clock nodes (used in the clock driver) - Modify gcr and rst node names. Changes since version 1: - NPCM8XX clock driver - Modify dt-binding. - Remove unsed definition and include. - Include alphabetically. - Use clock devm. - NPCM reset driver - Modify dt-binding. - Modify syscon name. - Add syscon support to NPCM7XX dts reset node. - use data structure. - NPCM8XX device tree: - Modify evb compatible name. - Add NPCM7xx compatible. - Remove disable nodes from the EVB DTS.
