Subject: [PATCH 5/7] USB: r8a66597-hcd: restore big-endian operation.
Date: Fri, 09 Mar 2012 16:38:51 +0000	[thread overview]
Message-ID: <1331311133-26937-5-git-send-email-thomas@codesourcery.com> (raw)
In-Reply-To: <1331311133-26937-1-git-send-email-thomas@codesourcery.com>

On SH, as of 37b7a97884ba64bf7d403351ac2a9476ab4f1bba we have to use the
endianess-agnostic I/O accessor functions.

This driver is also enabled in ARM's viper_defconfig as well as MIPS'
bcm47xx_defconfig and fuloong2e_defconfig -- I suppose none of these are
operating in big-endian mode, or this issue should already have been noticed
before.

The device is now recognized correctly for both litte-endian and big-endian
sh7785lcr, but I have not tested this any further, as the board is situated in
a remote data center.
