Subject: [PATCH 0/6] Fix sparse warnings for common qe library code
Date: Thu, 12 Mar 2020 17:28:21 -0500	[thread overview]
Message-ID: <20200312222827.17409-1-leoyang.li@nxp.com> (raw)

The QE code was previously only supported on big-endian PowerPC systems
that use the same endian as the QE device.  The endian transfer code is
not really exercised.  Recent updates extended the QE drivers to
little-endian ARM/ARM64 systems which makes the endian transfer really
meaningful and hence triggered more sparse warnings for the endian
mismatch.  Some of these endian issues are real issues that need to be
fixed.

While at it, fixed some direct de-references of IO memory space and
suppressed other __iomem address space mismatch issues by adding correct
address space attributes.
