* soc: fsl: qe: qe_io.c: use of_property_read_u32() in par_io_init()Rasmus Villemoes2019-12-091-4/+3
| | | | | | | | This is necessary for this to work on little-endian hosts. Reviewed-by: Timur Tabi <timur@kernel.org> Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Li Yang <leoyang.li@nxp.com>
* soc: fsl: qe: qe_io.c: access device tree property using be32_to_cpuRasmus Villemoes2019-12-091-4/+10
| | | | | | | | | We need to apply be32_to_cpu to make this work correctly on little-endian hosts. Reviewed-by: Timur Tabi <timur@kernel.org> Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Li Yang <leoyang.li@nxp.com>

* soc: fsl: qe: drop unneeded #includesRasmus Villemoes2019-12-091-2/+0
| | | | | | | | | | These includes are not actually needed, and asm/rheap.h and sysdev/fsl_soc.h are PPC-specific, hence prevent compiling QE for other architectures.

* soc: fsl: qe: avoid ppc-specific io accessorsRasmus Villemoes2019-12-091-22/+18
