From: Jacky Huang <ychuang3@nuvoton.com>

This patchset adds initial support for the Nuvoton ma35d1 SoC, including
initial device tree, clock driver, reset driver, and serial driver.

This patchset cover letter is based from the initial support for Nuvoton
ma35d1 to keep tracking the version history.

This patchset had been applied to Linux kernel 6.4.0-rc1-dirty
and tested on the Nuvoton ma35d1 SOM evaluation board.

(ma35d1 information: https://www.nuvoton.com/products/microprocessors/arm-cortex-a35-mpus/)
MA35D1 porting on linux-5.10.y can be found at: https://github.com/OpenNuvoton/MPU-Family

v10:
- Change from using ARCH_NUVOTON to using ARCH_MA35. The following patch files
have been modified:
- patch 1 arch/arm64/Kconfig.platforms
- patch 2 arch/arm64/configs/defconfig
- patch 7 arch/arm64/boot/dts/nuvoton/Makefile
- patch 8 drivers/clk/Makefile
drivers/clk/nuvoton/Kconfig
drivers/clk/nuvoton/Makefile
- patch 9 drivers/reset/Kconfig
- patch 10 drivers/tty/serial/Kconfig

v9:
- Combine MAINTAINERS patch into patch 5 'dt-bindings: arm: Add initial bindings
for Nuvoton platform'
- Modify clock driver
- Use the helper function for 64-bit division
- Fixed minor issues
- Modify reset driver
- Refine coding style and add required header files
- Add spin_lock protection
- Add error return handling to the serial driver probe function

v8:
- Remove '0005-dt-bindings-mfd-syscon-Add-nuvoton-ma35d1-sys-compat.patch' as it was applied.
- Modify MAINTAINERS NUVOTON MA35 and NPCM path settings
- Remove 'syscon' from dtsi 'sys' node and modify the corresponding yaml
- Modify clock driver
- Remove the header file and move definitions into .c files.
- Use parent_data instead of parent name.
- Modify serial driver
- Modify reset driver
- Modify reset register/offset lookup table to be indexed by reset id
- Combined reset and reboot structure

v7:
- Fixed dts system-management node and compatible driver
- move 'nuvoton,npcm-gcr.yaml' from 'binding/arm/nuvoton' to 'binding/soc/nuvoton'
- In ma35d1.dtsi, create the soc node for ma35d1 SoC
- Modify the issues found in serial driver
- Modify the issues found in clock driver
- Modify the IDs of reset driver to be contiguous numbers and use lookup table
to find register offset and bit position.
- Modify MAINTAINERS NUVOTON NPCM path as npcm directory name to nuvoton

v6:
- Combine nuvoton,ma35d1-clk.yaml and nuvoton,ma35d1-clk.h into one patch
- Combine nuvoton,ma35d1-reset.yaml and nuvoton,ma35d1-reset.h into one patch
- rename Documentation/devicetree/bindings/arm/npcm directory as nuvoton
- Remove patch for adding include/linux/mfd/ma35d1-sys.h as it's not required
- Update dtsi & dts files and move board-specific nodes to dts
- Modify reset driver
- Modify serial driver, fix coding style issues
- Modify clock driver, rewrite the PLL calculation functions

v5:
- Add ARCH_NUVOTON to arm64 Kconfig
- Add ARCH_NUVOTON to defconfig
- Add the clock driver
- Add the reset driver
- Add the serial driver
- Add us to the maintainer

v4:
- patch 4/5 is a resend
- Fixed dt_binding_check errors of nuvoton,ma35d1-clk.yaml
- Modify ma35d1.dtsi
1. Add a node hxt_24m
2. Fixed the base address of gic node
3. Add clocks and clock-names to clock node
- Fixed borad binding mistakes of nuvoton.yaml

v3:
- added patch 4/5 and 5/5
- introduce CONFIG_ARCH_NUVOTON option
- add initial bindings for Nuvoton Platform boards
- fixed coding style problem of nuvoton,ma35d1-clk.h
- added CAPLL to clock-controller node
- modify the chosen node of ma35d1-evb.dts
- modify clock yaml "clk-pll-mode" to "nuvoton,clk-pll-mode"

v2:
- fixed dt_binding_check failed of nuvoton,ma35d1-clk.yaml
