Subject: [PATCH v2] dt-bindings: soc: xilinx: Add support for K26 rev2 SOMs
Revision 2 is SW compatible with revision 1 but it is necessary to reflect
it in model and compatible properties which are parsed by user space.
Rev 2 has improved a power on boot reset and MIO34 shutdown glich
improvement done via an additional filter in the GreenPak chip.
Signed-off-by: Michal Simek <michal.simek@....com>

Changes in v2:
- Support older combinations
I want to support all versions we created:
All of them:
-rev2, -rev1, -revB, -revA, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
rev1:
-rev1, -revB, -revA, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
revB:
-revB, -revA, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
revA:
-revA, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
And also single one are permitted:
-revB, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
-rev1, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
-rev2, "xlnx,zynqmp-smk-k26", "xlnx,zynqmp"
I didn't find a way to pretty much all the time force that there must be
both "xlnx,zynqmp-smk-k26", "xlnx,zynqmp" that's why there is only
requested to have xlnx,zynqmp. If you find a way how to encode it please
let me know.
