Ok, thanks for the information, this is exactly what we need in the changelog text for the platform, and (if you send a pull request) in the tag description. > Yes, we have console device driver ready. Please refer to > https://github.com/OpenNuvoton/MA35D1_linux-5.4.y/blob/master/drivers/tty/serial/ma35d1_serial.c. > But I think we have to fix coding style and have more review on it.

I would prefer to have it included, but it looks like this has never been reviewed, and I can immediately see a few things that need changes before it can get included, so I suppose we could merge the platform without it. The reason I'd like to have it included is that without any I/O devices it is obvious that the code you are sending has never been tested on the kernel version you are sending it against, and that makes it more likely that there are bugs. If the platform for some reason does not make it into v5.19, I would ask you to include the serial driver in the series so we can merge a working initial branch for v5.20. In the meantime, please post the driver for review to the linux-kernel and linux-serial lists by itself, and keep me on Cc. > And thank you to remind us to create an entry in MAINTAINERS file.
