From b5a5d2bd967781818ab1eadcd3ce779d01676e2e Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 5 Dec 2015 19:24:22 +0100 Subject: arm: socfpga: socrates: Probe DWC2 UDC from OF instead of hard-coded data This patch adds the necessary OF alias for the UDC node, which let's the code locate the DWC2 UDC base address in OF instead of hard-coding it into the U-Boot binary. The code is adjusted to use the address from OF instead of the hard-coded one. Finally, the hard-coded address is removed and USB DM support is enabled.
