+Subject: [PATCH 5001/5006] dt-bindings: phy: Add special clock for Allwinner
+ H616 PHY
+
+The USB PHY IP in the Allwinner H616 SoC requires a quirk that involves
+some resources from port 2's PHY and HCI IP. In particular the PMU clock
+for port 2 must be surely ungated before accessing the REG_HCI_PHY_CTL
+register of port 2. To allow each USB port to be controlled
+independently of port 2, we need a handle to that particular PMU clock
+in the *PHY* node, as the HCI and PHY part might be handled by separate
+drivers.
+
+Add that clock to the requirements of the H616 PHY binding, so that a
+PHY driver can apply the quirk in isolation, without requiring help from
+port 2's HCI driver.
