-Subject: [PATCH 1/7] usb: host: fotg2: add Gemini-specific handling
-
-The Cortina Systems Gemini has bolted on a PHY inside the
-silicon that can be handled by six bits in a MISC register in
-the system controller.
-
-If we are running on Gemini, look up a syscon regmap through
-a phandle and enable VBUS and optionally the Mini-B connector.
-
-If the device is flagged as "wakeup-source" using the standard
-DT bindings, we also enable this in the global controller for
-respective port.

-Subject: [PATCH 4/7] ARM: dts: gemini: Add thermal zone to DIR-685
-
-The DIR-685 can now exploit the thermal zone added by the
-drive temperature sensor inside the hard drive. We have
-patched the libata subsystem to assign the device nodes
-properly to the SCSI devices and this is what the drivetemp
-driver will use to populate the sensor and the thermal
-zone, so pick that up into the thermal zone and let this
-control the fan.
-
-The hardware lacks an embedded temperature sensor so the
-D-Link vendor firmware uses this method to control the
-temperature of the NAS enclosure using the thermal sensor
-inside the hard drive.
-
-The drive temperature trigger points to be used comes from
-the vendor firmware.
