Subject: [PATCH v2 net-next 4/4] dt-bindings: net: dsa: sja1105: convert to YAML schema
From: Vladimir Oltean <vladimir.oltean@....com>
Since the sja1105 driver no longer has any custom device tree
properties, the conversion is trivial.

+title: NXP SJA1105 Automotive Ethernet Switch Family Device Tree Bindings
+
+description:
+ The SJA1105 SPI interface requires a CS-to-CLK time (t2 in UM10944.pdf) of at
+ least one half of t_CLK. At an SPI frequency of 1MHz, this means a minimum
+ cs_sck_delay of 500ns. Ensuring that this SPI timing requirement is observed
+ depends on the SPI bus master driver.

-NXP SJA1105 switch driver
-=========================
-
-Required properties:
-
-- compatible:
- Must be one of:
- - "nxp,sja1105e"
- - "nxp,sja1105t"
- - "nxp,sja1105p"
- - "nxp,sja1105q"
- - "nxp,sja1105r"
- - "nxp,sja1105s"
-
- Although the device ID could be detected at runtime, explicit bindings
- are required in order to be able to statically check their validity.
- For example, SGMII can only be specified on port 4 of R and S devices,
- and the non-SGMII devices, while pin-compatible, are not equal in terms
- of support for RGMII internal delays (supported on P/Q/R/S, but not on
- E/T).
-
-See Documentation/devicetree/bindings/net/dsa/dsa.txt for the list of standard
-DSA required and optional properties.
-
-Other observations
-------------------
-
-The SJA1105 SPI interface requires a CS-to-CLK time (t2 in UM10944) of at least
-one half of t_CLK. At an SPI frequency of 1MHz, this means a minimum
-cs_sck_delay of 500ns. Ensuring that this SPI timing requirement is observed
-depends on the SPI bus master driver.

-Example
--------
-
-Ethernet switch connected via SPI to the host, CPU port wired to enet2:

- port@0 {
- /* ETH5 written on chassis */
