From ae3f672cab5d1fef9fc4c6436e9d7e347eba0b13 Mon Sep 17 00:00:00 2001 From: Alexander Monakov Date: Sun, 4 Mar 2018 21:18:07 +0300 Subject: [PATCH] phy: berlin-usb: adjust USB_PHY_RX_CTRL init flags Make the value written into the USB_PHY_RX_CTRL configuration register match 0xAA79 value written by manufacturer-supplied kernels for Sony NSZ-GS7 (Berlin2 SoC), Google Chromecast and Valve Steam Link (BG2CD). This fixes timeouts communicating to the internal hub on Steam Link.
