From f3419735279564d40467ebe4147d8a41cef00685 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Sun, 20 Nov 2016 21:26:02 +0000 Subject: [PATCH] usb: dwc2: Do not set host parameter in peripheral mode Since commit "usb: dwc2: Improve handling of host and device hwparams" the host mode specific hardware parameter aren't initialized in peripheral mode from the register settings anymore. So we better do not set them in this case which avoids the following warnings on bcm2835: 256 invalid for host_nperio_tx_fifo_size. Check HW configuration. 512 invalid for host_perio_tx_fifo_size. Check HW configuration.
