Title: [serial] use hw flow control if supported Status in “linux” package in Ubuntu: Fix Committed Status in “linux” source package in Trusty: Fix Committed Bug description: HP Moonshot cartridges support hardware flow control, but right now only software assisted hw flow control is supported. This patch from upstream enables this functionality when exposed by firmware: commit 06aa82e498c144c7784a6f3d3b55458b272d6146 Author: Murali Karicheri <[email protected]> Date: Thu May 1 15:04:53 2014 -0400 serial: uart: add hw flow control support configuration 8250 uart driver currently supports only software assisted hw flow control. The software assisted hw flow control maintains a hw_stopped flag in the tty structure to stop and start transmission and use modem status interrupt for the event to drive the handshake signals. This is not needed if hw has flow control capabilities. This patch adds a DT attribute for enabling hw flow control for a uart port. Also skip stop and start if this flag is present in flag field of the port structure.
