Subject: [PATCH 5/5] dt-bindings: net: sms911x: Convert to json-schema
Date: Thu, 20 May 2021 15:58:39 +0200	[thread overview]
Message-ID: <f3f33f75c8911697f2c1dbde626f01187199bdc2.1621518686.git.geert+renesas@glider.be> (raw)
In-Reply-To: <cover.1621518686.git.geert+renesas@glider.be>

Convert the Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x
Controller Device Tree binding documentation to json-schema.

Document missing properties.
Make "phy-mode" not required, as many DTS files do not have it, and the
Linux drivers falls back to PHY_INTERFACE_MODE_NA.
Correct nodename in example.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

I have listed Shawn as the maintainer, as he wrote the original
bindings.  Shawn: Please scream if this is inappropriate ;-)

I left "additionalProperties: true", as there are lots of bus-specific
properties ("qcom,*", "samsung,*", "fsl,*", "gpmc,*", ...) to be found,
that actually depend on the compatible value of the parent node.

-Required properties:
-- compatible : Should be "smsc,lan<model>", "smsc,lan9115"
-- reg : Address and length of the io space for SMSC LAN
-- interrupts : one or two interrupt specifiers
-  - The first interrupt is the SMSC LAN interrupt line
-  - The second interrupt (if present) is the PME (power
-    management event) interrupt that is able to wake up the host
-     system with a 50ms pulse on network activity
-- phy-mode : See ethernet.txt file in the same directory
-
-Optional properties:
-- reg-shift : Specify the quantity to shift the register offsets by
-- reg-io-width : Specify the size (in bytes) of the IO accesses that
-  should be performed on the device.  Valid value for SMSC LAN is
-  2 or 4.  If it's omitted or invalid, the size would be 2.
-- smsc,irq-active-high : Indicates the IRQ polarity is active-high
-- smsc,irq-push-pull : Indicates the IRQ type is push-pull
-- smsc,force-internal-phy : Forces SMSC LAN controller to use
