Subject: [PATCH 11/13] dt-bindings: ipmi: Convert IPMI-SMIC bindings to json-schema
Date: Wed, 26 Feb 2020 18:08:59 +0000	[thread overview]
Message-ID: <20200226180901.89940-12-andre.przywara@arm.com> (raw)
In-Reply-To: <20200226180901.89940-1-andre.przywara@arm.com>

Convert the generic IPMI controller bindings to DT schema format
using json-schema.

I removed the formerly mandatory device-type property, since this
is deprecated in the DT spec, except for the legacy CPU and memory
nodes.

-IPMI device
-
-Required properties:
-- compatible: should be one of ipmi-kcs, ipmi-smic, or ipmi-bt
-- device_type: should be ipmi
-- reg: Address and length of the register set for the device
-
-Optional properties:
-- interrupts: The interrupt for the device.  Without this the interface
-	is polled.
-- reg-size - The size of the register.  Defaults to 1
-- reg-spacing - The number of bytes between register starts.  Defaults to 1
-- reg-shift - The amount to shift the registers to the right to get the data
-	into bit zero.
-
-Example:
-
-smic@fff3a000 {
-	compatible = "ipmi-smic";
-	device_type = "ipmi";
-	reg = <0xfff3a000 0x1000>;
-	interrupts = <0 24 4>;
-	reg-size = <4>;
-	reg-spacing = <4>;
