From df115f3ee9ea703e1209392cd08f8d6783244721 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 25 May 2015 20:27:29 +0100 Subject: [PATCH] MIPS: Octeon: Set OHCI and EHCI MMIO byte order to match CPU The Octeon OHCI is now supported by the ohci-platform driver, and USB_OCTEON_OHCI is marked as deprecated. However, it is currently still necessary to enable it in order to select USB_OHCI_BIG_ENDIAN_MMIO. Make CPU_CAVIUM_OCTEON select that as well, so that USB_OCTEON_OHCI is really obsolete. The old ohci-octeon and ehci-octeon drivers also only enabled big-endian MMIO in case the CPU was big-endian. Make the selections of USB_EHCI_BIG_ENDIAN_MMIO and USB_OHCI_BIG_ENDIAN_MMIO conditional, to match this.
