[PATCH v8 00/16] Introduce Nuvoton Arbel NPCM8XX BMC SoC

[Tomer Maimon <tmaimon77@gmail.com>]

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.

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.
