Subject: [GIT PULL 09/15] intel_th: Enumerate Low Power Path output port type
Date: Fri, 25 Aug 2017 19:16:00 +0300 [thread overview]
Message-ID: <20170825161606.2670-10-alexander.shishkin@linux.intel.com> (raw)
In-Reply-To: <20170825161606.2670-1-alexander.shishkin@linux.intel.com>
Trace Hub 2.x adds Low Power Path (LPP) output port type, which provides
a low power mode trace path from sources to PTI or BSSB.
This adds an output subdevice for the LPP port.
