It would be better if this goes via my tree. There is at least one
series which also touches the same parts in these files that's why there
will be collisions.
If you can review that I will take it via my tree and arm-soc guys to
mainline.
Thanks,
Michal

+--------------------------------------------------------------------------
+The Zynq UltraScale+ MPSoC has several different resets.
+
+See Chapter 36 of the Zynq UltraScale+ MPSoC TRM (UG) for more information
+about zynqmp resets.
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+Required Properties:
+- compatible: "xlnx,zynqmp-reset"
+- #reset-cells: Specifies the number of cells needed to encode reset
+ line, should be 1
+
+-------
+Example
+-------
+
+firmware {
+ zynqmp_firmware: zynqmp-firmware {
+ compatible = "xlnx,zynqmp-firmware";
+ method = "smc";
+
+ zynqmp_reset: reset-controller {
+ compatible = "xlnx,zynqmp-reset";
+ #reset-cells = <1>;
+ };
+ };
+};
+
+Specifying reset lines connected to IP modules
+==============================================
+
+Device nodes that need access to reset lines should
+specify them as a reset phandle in their corresponding node as
+specified in reset.txt.
+
+For list of all valid reset indicies see
+<dt-bindings/reset/xlnx-zynqmp-resets.h>
+
+Example:
+
+serdes: zynqmp_phy@fd400000 {
