Subject: [PATCH v3 1/2] dt-bindings: nvmem: Add binding for RAVE SP EEPROM driver
Date: Mon, 30 Apr 2018 22:29:51 -0700 [thread overview]
Message-ID: <20180501052952.26765-2-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180501052952.26765-1-andrew.smirnov@gmail.com>
Add Device Tree bindings for RAVE SP EEPROM driver - an MFD cell of
parent RAVE SP driver (documented in
Documentation/devicetree/bindings/mfd/zii,rave-sp.txt).

+Zodiac Inflight Innovations RAVE EEPROM Bindings
+
+RAVE SP EEPROM device is a "MFD cell" device exposing physical EEPROM
+attached to RAVE Supervisory Processor. It is expected that its Device
+Tree node is specified as a child of the node corresponding to the
+parent RAVE SP device (as documented in
+Documentation/devicetree/bindings/mfd/zii,rave-sp.txt)
+
+Required properties:
+
+- compatible: Should be "zii,rave-sp-eeprom"
+
+Optional properties:
+
+- zii,eeprom-name: Unique EEPROM identifier describing its function in the
+ system. Will be used as created NVMEM deivce's name.
+
+Data cells:
+
+Data cells are child nodes of eerpom node, bindings for which are
+documented in Documentation/bindings/nvmem/nvmem.txt
+
+Example:
+
+ rave-sp {
+ compatible = "zii,rave-sp-rdu1";
+ current-speed = <38400>;
+
+ eeprom@a4 {
+ compatible = "zii,rave-sp-eeprom";
+ reg = <0xa4 0x4000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ zii,eeprom-name = "main-eeprom";
+
+ wdt_timeout: wdt-timeout@81 {
+ reg = <0x81 2>;
+ };
+ };
+ }
