Merge tag 'regmap-fix-v4.5-big-endian' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap fix from Mark Brown:
"A single revert back to v4.4 endianness handling.
Commit 29bb45f25ff3 ("regmap-mmio: Use native endianness for
read/write") attempted to fix some long standing bugs in the MMIO
implementation for big endian systems caused by duplicate byte
swapping in both regmap and readl()/writel(). Sadly the fix makes
things worse rather than better, so revert it for now"
