From 543eb12ecd91df324554b8abc8d52e965bd4922b Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 21 Jul 2020 10:46:02 +0200 Subject: [PATCH] usb: xhci: Add missing endian conversions (cpu_to_leXX / leXX_to_cpu) While trying to use the U-Boot xHCI driver on the MIPS Octeon platform, which is big endian, I noticed that the driver is missing a few endian conversion calls. This patch adds these missing endian conversion calls.
