Subject: intel_th: Enumerate Low Power Path output port type
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=92758af39ab73f470f765b7213fb4c88c7e5ca03;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

intel_th: Enumerate Low Power Path output port type

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.
