[PATCH 2/3] gemini: Create patches and config for kernel v5.15
Linus Walleij
linus.walleij at linaro.org
Mon Apr 11 14:46:18 PDT 2022
This creates a v5.15 baseline for the Gemini platform.
The main new attraction is the new crypto driver from
Corentin Labbe that we activate in the new config.
Config was refreshed.

+Subject: [PATCH 1/2] 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.
