Subject: [PATCH v3 0/2] arm64: dts: qcom: sc7180-trogdor: Wire up USB

Wiring up the USB hub to the connectors allows us to gain the proper
'connect_type' and 'removable' values in sysfs for the USB devices on
sc7180 trogdor devices. These two patches are split off of a larger
series[1] so they can land faster and because we've come to the
conclusion that the DisplayPort path is going to connect to the
cros-ec-typec node, not the usb-c-connector node.

The first patch adds the pogo pin binding to describe the detachable
keyboards found on some trogdor devices (actually strongbad). The second
patch is the dts changes required to wire up all the USB stuff. This is
sufficient to set the sysfs properties for USB devices so that the
builtin USB webcam is considered "fixed" or hard-wired while devices
plugged into the connectors or the keyboard are considered "removable"
or hotpluggable.

Chamges from v2 https://lore.kernel.org/r/20250205233016.1600517-1-swboyd@chromium.org
 * Make binding specific to keyboard and move to usb/
 * Update dts to reflect new compatible string for pogo pin keyboard

Changes from v1 https://lore.kernel.org/r/20240210070934.2549994-1-swboyd@chromium.org
 * Split out of larger series
 * Added description to DT binding
 * Removed DP part of dts changes
