The serial port on the RPi header has a baud of 1,500,000. This is fine for most tools, but some are capped at the values present in the baud tables in various places in the Linux kernel and other utilities.
How do I change the baud to 460800? I've found the uarts in rk3399.dtsi in the kernel tree, but am unsure how their clocks are actually generated.
As expected software seems unable to change the speed of the serial port.
