From 9981a3146cd9f07075dcac1611ca7c06f597d66b Mon Sep 17 00:00:00 2001 From: Victor Kamensky Date: Sat, 16 Nov 2013 02:01:14 +0200 Subject: mfd: omap-usb-host: Raw read and write endian fix All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.
