From afb19d65d9a69635bed197f1d3be492e6bfe85d4 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 12 Sep 2017 19:07:21 +0200 Subject: [PATCH] ARM: rmobile: Move HSUSB configuration to board on Salvator-X In order to use ehci-generic driver, move the configuration of HSUSB block into the board file. This configuration should not have been in the Gen3 EHCI USB driver in the first place, so move it to the board file until there is a proper infrastructure and driver for the HSUSB block.
