+ Devicetree (DT) ABI
+
+I. Regarding stable bindings/ABI, we quote from the 2013 ARM mini-summit
+ summary document:
+
+ "That still leaves the question of, what does a stable binding look
+ like? Certainly a stable binding means that a newer kernel will not
+ break on an older device tree, but that doesn't mean the binding is
+ frozen for all time. Grant said there are ways to change bindings that
+ don't result in breakage. For instance, if a new property is added,
+ then default to the previous behaviour if it is missing. If a binding
+ truly needs an incompatible change, then change the compatible string
+ at the same time. The driver can bind against both the old and the
+ new. These guidelines aren't new, but they desperately need to be
+ documented."
+
+II. General binding rules
+
+ 1) Maintainers, don't let perfect be the enemy of good. Don't hold up a
+ binding because it isn't perfect.
+
+ 2) Use specific compatible strings so that if we need to add a feature (DMA)
+ in the future, we can create a new compatible string. See I.
+
+ 3) Bindings can be augmented, but the driver shouldn't break when given
+ the old binding. ie. add additional properties, but don't change the
+ meaning of an existing property. For drivers, default to the original
+ behaviour when a newly added property is missing.
+
+ 4) Don't submit bindings for staging or unstable. That will be decided by
+ the devicetree maintainers *after* discussion on the mailinglist.
+
+III. Notes
+
+ 1) This document is intended as a general familiarization with the process as
+ decided at the 2013 Kernel Summit. When in doubt, the current word of the
+ devicetree maintainers overrules this document. In that situation, a patch
+ updating this document would be appreciated.
Main node required properties:
- compatible : should be one of:
+ "arm,gic-400"
"arm,cortex-a15-gic"
"arm,cortex-a9-gic"
"arm,cortex-a7-gic"
tree. Those nodes are designated as clock providers. Clock consumer
nodes use a phandle and clock specifier pair to connect clock provider
outputs to clock inputs. Similar to the gpio specifiers, a clock
-specifier is an array of one more more cells identifying the clock
+specifier is an array of zero, one or more cells identifying the clock
output on a device. The length of a clock specifier is defined by the
value of a #clock-cells property in the clock provider node.
Required properties:
- #address-cells : Should be <1>
- #size-cells : Should be <0>
- - device_type : Should be "mdio"
- compatible : Should be "marvell,mv64360-mdio"
Example:
mdio {
#address-cells = <1>;

interrupt-parent = <&PIC>;
serial port.
Required properties:

- device_type = "serial";
compatible = "marvell,mv64360-mpsc";
reg = <0x8000 0x38>;
virtual-reg = <0xf1008000>;
- interrupts: Should contain macb interrupt
- phy-mode: String, operation mode of the PHY interface.

};
* Ethernet port node
Required port properties:
- - device_type: shall be "network".
- compatible: shall be one of "marvell,orion-eth-port",
"marvell,kirkwood-eth-port".
- reg: port number relative to ethernet controller, shall be 0, 1, or 2.
mdio-bus {

};
};
marvell,tx-checksum-limit = <1600>;
ethernet@0 {
- device_type = "network";
compatible = "marvell,orion-eth-port";

Required properties:
- - device_type : Should be "ethernet-phy"
- interrupts : <a b> where a is the interrupt number and b is a
field that represents an encoding of the sense and level
information for the interrupt. This should be encoded based on

services interrupts for this device.
- reg : The ID number for the phy, usually a small integer
- - linux,phandle : phandle for this node; likely referenced by an
- ethernet controller node.
Optional Properties:
ethernet-phy@0 {
compatible = "ethernet-phy-ieee802.3-c22";
- linux,phandle = <2452000>;
interrupt-parent = <40000>;

Example:
ucc_pin@01 {
- linux,phandle = <140001>;
pio-map = <
/* port pin dir open_drain assignment has_irq */

+
+ Submitting devicetree (DT) binding patches
+
+I. For patch submitters
+
+ 0) Normal patch submission rules from Documentation/SubmittingPatches
+ applies.
+
+ 1) The Documentation/ portion of the patch should be a separate patch.
+
+ 2) Submit the entire series to the devicetree mailinglist at
+
+ devicetree@vger.kernel.org
+
+II. For kernel maintainers
+
+ 1) If you aren't comfortable reviewing a given binding, reply to it and ask
+ the devicetree maintainers for guidance. This will help them prioritize
+ which ones to review and which ones are ok to let go.
+
+ 2) For driver (not subsystem) bindings: If you are comfortable with the
+ binding, and it hasn't received an Acked-by from the devicetree
+ maintainers after a few weeks, go ahead and take it.
+
+ Subsystem bindings (anything affecting more than a single device)
+ then getting a devicetree maintainer to review it is required.
+
+ 3) For a series going though multiple trees, the binding patch should be
+ kept with the driver using the binding.
+
+III. Notes
+
+ 0) Please see ...bindings/ABI.txt for details regarding devicetree ABI.
+
+ 1) This document is intended as a general familiarization with the process as
+ decided at the 2013 Kernel Summit. When in doubt, the current word of the
+ devicetree maintainers overrules this document. In that situation, a patch
+ updating this document would be appreciated.
