From c430131a02d677aa708f56342c1565edfdacb3c0 Mon Sep 17 00:00:00 2001 From: Jan Andersson Date: Tue, 3 May 2011 20:11:57 +0200 Subject: USB: EHCI: Support controllers with big endian capability regs The two first HC capability registers (CAPLENGTH and HCIVERSION) are defined as one 8-bit and one 16-bit register. Most HC implementations have selected to treat these registers as part of a 32-bit register, giving the same layout for both big and small endian systems. This patch adds a new quirk, big_endian_capbase, to support controllers with big endian register interfaces that treat HCIVERSION and CAPLENGTH as individual registers.
