Subject: [PATCH v3 5/6] dt-bindings: nvmem: Add bindings for ZynqMP nvmem driver
Date: Mon, 21 Jan 2019 23:08:34 +0530 [thread overview]
Message-ID: <20190121173835.21173-6-nava.manne@xilinx.com> (raw)
In-Reply-To: <20190121173835.21173-1-nava.manne@xilinx.com>
Add documentation to describe Xilinx ZynqMP nvmem driver
bindings.
Signed-off-by: Nava kishore Manne <nava.manne@xilinx.com>

+= Zynq UltraScale+ MPSoC nvmem firmware driver binding =
+--------------------------------------------------------------------------
+The nvmem_firmware node provides access to the hardware related data
+like soc revision, IDCODE... etc, By using the firmware interface.
+
+Required properties:
+- compatible: should be "xlnx,zynqmp-nvmem-fw"
+
+= Data cells =
+Are child nodes of silicon id, bindings of which as described in
+bindings/nvmem/nvmem.txt
+
+-------
+ Example
+-------
+firmware {
+ zynqmp_firmware: zynqmp-firmware {
+ compatible = "xlnx,zynqmp-firmware";
+ method = "smc";
+
+ nvmem_firmware {
+ compatible = "xlnx,zynqmp-nvmem-fw";
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ /* Data cells */
+ soc_revision: soc_revision {
+ reg = <0x0 0x4>;
+ };
+ };
+ };
+};
+
+= Data consumers =
+Are device nodes which consume nvmem data cells.
+
+For example:
+ pcap {
+ ...
+
+ nvmem-cells = <&soc_revision>;
+ nvmem-cell-names = "soc_revision";
+
+ ...
+ };
