Subject: [PATCH v9 00/16] Introduce Nuvoton Arbel NPCM8XX BMC SoC
This patchset adds initial support for the Nuvoton
Arbel NPCM8XX Board Management controller (BMC) SoC family.
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:
- Stephen Boyd: https://www.spinics.net/lists/arm-kernel/msg996551.html
Changes since version 8:
- NPCM8XX clock driver
- Move configuration place.
- Add space before and aftre '{' '}'.
- Handle devm_of_clk_add_hw_provider function error.
Changes since version 7:
- NPCM8XX clock driver
- The clock and reset registers using the same memory region,
due to it the clock driver should claim the ioremap directly
without checking the memory region.
Changes since version 6:
- NPCM reset driver
- Modify warning message.
- dt-bindings: serial: 8250: Add npcm845 compatible string patch accepted, due
to it the patch removed from the patchset.
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.
