The objective of this series is to add rs485 support for the Raspberry Pi auxiliary uart (patch [6/8] and [7/8]). But I'm taking the opportunity to improve rs485 support for any 8250-compatible uart: * rs485 devicetree properties support (patch [2/8]). * rs485 serial console support (patch [8/8]). * various fixes and cleanups. Please review and test. Thanks!
