Thank you very much for all the assistance you have provided. Once the device tree is merged, we will start submitting drivers such as pinctrl, gpio, rtc, and so on. Best Regards, Jacky Huang

I think you can start submitting all the drivers to their respective maintainers now, just mention that the SoC support is currently in linux-next in case they get confused about the dependencies.

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-rc5 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 v13: - Modify serial driver - Added a check for oops_in_progress in ma35d1serial_console_write to determine whether to perform the spin_lock. - Rebased drivers/tty/serial/Kconfig and recreate the patch - Rebased MAINTAINERS and recreate the patch v12: - Modify serial driver - Added PORT_MA35 to include/uapi/linux/serial_core.h, and apply to the port->type of ma35d1 serial driver - Added check for the return value of ioremap() - Fixed several coding issues - Rebase MAINTAINERS and recreate the patch v11: - Rebase on top of 2023.05.24 - Modify serial driver - Fixed several coding style issues - Fixed ma35d1serial_set_mctrl() - Added the 'MA35_' prefix to all register and bit field definitions. - Used 'ttyNVT' instead of 'ttyS' - Modify clock driver - Added 'source nuvoton/Kconfig' to drivers/clk/Kconfig - Fixed several coding issues - Removed unnecessary inline specifier - Modify reset driver - Fixed typo and added comments - Modify ma35d1.dtsi l2-cache node - Added cache-unified and cache-size properties v10: - Change from using ARCH_NUVOTON to using ARCH_MA35.
