I am using P2040 for serial communication with other devices. SDK Version is 2.0.0 and Linux 4.1.8. 8250 Driver in Linux is enabled for achieving serial communication.
We are looking to support RS485 with P2040 board. When I searched in net, I found that RS485 support can be enabled by setting values in device tree. But the linux driver code of 8250 does not seems to be taking dtb values.
How can I enable RS485 support for P2040. Any help will be appreciated.
