From aed609c40c6f676354bd7cf23a51339e7adc3c4c Mon Sep 17 00:00:00 2001 From: Jonathan Neuschäfer Date: Tue, 19 Mar 2019 16:24:18 +0100 Subject: ARM: dts: imx50: Add PHY node for usbotg and adjust clocks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Even though the ChipIdea USB controller binding[1] doesn't specify the properties that reference a PHY as required, the Linux driver requires[2] such a reference. The clock situation is like on i.MX53: The USB controller is clocked from IMX5_CLK_USBOH3_GATE and the PHY from IMX5_CLK_USB_PHY1_GATE.
