+Subject: arm64: dts: qcom: Fix 'interrupt-map' parent address cells
+
+From: Rob Herring <robh@kernel.org>
+
+commit 0ac10b291bee84b00bf9fb2afda444e77e7f88f4 upstream.
+
+The 'interrupt-map' in several QCom SoCs is malformed. The '#address-cells'
+size of the parent interrupt controller (the GIC) is not accounted for.

+Subject: usb: typec: ucsi: Check for notifications after init
+
+From: Christian A. Ehrhardt <lk@c--e.de>
+
+commit 808a8b9e0b87bbc72bcc1f7ddfe5d04746e7ce56 upstream.
+
+The completion notification for the final SET_NOTIFICATION_ENABLE
+command during initialization can include a connector change
+notification. However, at the time this completion notification is
+processed, the ucsi struct is not ready to handle this notification.
+As a result the notification is ignored and the controller
+never sends an interrupt again.
+
+Re-check CCI for a pending connector state change after
+initialization is complete. Adjust the corresponding debug
+message accordingly.
+
+Fixes: 71a1fa0df2a3 ("usb: typec: ucsi: Store the notification mask")

+
+commit ce4c8d21054ae9396cd759fe6e8157b525616dc4 upstream.
+
+Fix issues when initially checking for a connector change:
+- Use the correct connector number not the entire CCI.
+- Call ->read under the PPM lock.
+- Remove a bogus READ_ONCE.
