In-Reply-To: <1440020192-23754-1-git-send-email-jeremy.linton@arm.com> References: <1440020192-23754-1-git-send-email-jeremy.linton@arm.com> Message-ID: <1440020192-23754-3-git-send-email-jeremy.linton@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This enables USB on the ARM juno board when booted with an ACPI kernel. The PNP id comes from the PNP/ACPI registry and describes an EHCI controller without debug.
