See Chapter 26 of the Zynq TRM (UG585) for more information about Zynq resets. Required properties: - compatible: "xlnx,zynq-reset" - reg: SLCR offset and size taken via syscon <0x200 0x50> - syscon: <&slcr> This should be a phandle to the Zynq's SLCR register. - #reset-cells: Must be 1 The Zynq Reset Manager needs to be a child node of the SLCR. Example: rstc: rstc@200 { compatible = "xlnx,zynq-reset"; reg = <0x200 0x50>; #reset-cells = <1>; syscon = <&slcr>; }; > Thanks, > Michal > > > -- > Michal Simek, Ing.
