Subject: [PATCH v2 1/4] dt-bindings: firmware: Add bindings for ZynqMP firmware
Date: Wed, 17 Jan 2018 12:20:31 -0800 [thread overview]
Message-ID: <1516220434-22204-2-git-send-email-jollys@xilinx.com> (raw)
In-Reply-To: <1516220434-22204-1-git-send-email-jollys@xilinx.com>
Add documentation to describe Xilinx ZynqMP firmware driver
bindings. Firmware driver provides an interface to firmware
APIs. Interface APIs can be used by any driver to communicate
to PMUFW (Platform Management Unit).

+ - method: The method of calling the PM-API firmware layer.
+ Permitted values are:
+ - "smc" : To be used in configurations without a hypervisor
+ - "hvc" : To be used when hypervisor is present
+
+Examples:
+ zynqmp_firmware: zynqmp-firmware {
+ compatible = "xlnx,zynqmp-firmware";
+ method = "smc";
+ };
