[PATCH v3 0/3] arm64/slimbus/dt-bindings: convert to DT Schema, minor cleanups

[Krzysztof Kozlowski]

Hi,

Changes since v2
================
1. None, rebased and dropped applied patches.

Changes since v1
================
1. Fix commit title typo (Steev).
2. Add Rb/Tb tags.

Dependencies
============
No dependencies. Binding patches are independent from DTS.

Best regards,
Krzysztof

-SLIM(Serial Low Power Interchip Media Bus) bus
-
-SLIMbus is a 2-wire bus, and is used to communicate with peripheral
-components like audio-codec.
-
-Required property for SLIMbus controller node:
-- compatible	- name of SLIMbus controller
-
-Child nodes:
-Every SLIMbus controller node can contain zero or more child nodes
-representing slave devices on the bus. Every SLIMbus slave device is
-uniquely determined by the enumeration address containing 4 fields:
-Manufacturer ID, Product code, Device index, and Instance value for
-the device.
-If child node is not present and it is instantiated after device
-discovery (slave device reporting itself present).
-
-In some cases it may be necessary to describe non-probeable device
-details such as non-standard ways of powering up a device. In
-such cases, child nodes for those devices will be present as
-slaves of the SLIMbus controller, as detailed below.
-
-Required property for SLIMbus child node if it is present:
-- reg		- Should be ('Device index', 'Instance ID') from SLIMbus
-		  Enumeration  Address.
-		  Device Index Uniquely identifies multiple Devices within
-		  a single Component.
-		  Instance ID Is for the cases where multiple Devices of the
-		  same type or Class are attached to the bus.
-
-- compatible	-"slimMID,PID". The textual representation of Manufacturer ID,
-	 	  Product Code, shall be in lower case hexadecimal with leading
-		  zeroes suppressed
-
-Optional property for SLIMbus child node if it is present:
-- slim-ifc-dev	- Should be phandle to SLIMBus Interface device.
-		  Required for devices which deal with streams.
-
-SLIMbus example for Qualcomm's slimbus manager component:
-
-	slim@28080000 {
-		compatible = "qcom,apq8064-slim", "qcom,slim";
