+Subject: [PATCH] phy: bcm-ns-usb2: new driver for USB 2.0 PHY on Northstar
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Northstar is a family of SoCs used in home routers. They have USB 2.0
+and 3.0 controllers with PHYs that need to be properly initialized.
+This driver provides PHY init support in a generic way and can be bound
+with an EHCI controller driver.
+There are (just a few) registers being defined in bcma header. It's
+because DMU/CRU registers will be also needed in other drivers. We will
+need them e.g. in PCIe controller/PHY driver and at some point probably
+in clock driver for BCM53573 chipset. By using include/linux/bcma/ we
+avoid code duplication.

++Driver for Broadcom Northstar USB 2.0 PHY
++
++Required properties:
++- compatible: brcm,ns-usb2-phy
++- reg: iomem address range of DMU (Device Management Unit)
++- reg-names: "dmu", the only needed & supported reg right now
++- clocks: USB PHY reference clock
++- clock-names: "phy-ref-clk", the only needed & supported clock right now
++
++To initialize USB 2.0 PHY driver needs to setup PLL correctly. To do this it
++requires passing phandle to the USB PHY reference clock.
++
++Example:
++ usb2-phy {
++ compatible = "brcm,ns-usb2-phy";
++ reg = <0x1800c000 0x1000>;
++ reg-names = "dmu";
