From c33f4f24b888236b725a9972e0fe5ac6575c68ec Mon Sep 17 00:00:00 2001 From: Al Cooper <alcooperx@gmail.com> Date: Tue, 12 May 2020 11:00:19 -0400 Subject: [PATCH] usb: host: Add ability to build new Broadcom STB USB drivers Add the build system changes needed to get the Broadcom STB XHCI, EHCI and OHCI functionality working. The OHCI support does not require anything unique to Broadcom so the standard ohci-platform driver is being used. Also update MAINTAINERS.
