From edfaf05c2fcb853fcf35f12aeb9c340f5913337f Mon Sep 17 00:00:00 2001 From: Victor Kamensky Date: Tue, 15 Apr 2014 20:37:46 +0300 Subject: ARM: OMAP2+: 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.
