Convert binding doc tcan4x5x.txt to yaml.

Can we somehow reference bosch,mram-cfg from the bosch,m_can.yaml?
I have searched for yaml files that tries the same, but it's usually
includes a whole node.
I have also tried:
$ref: /schema/bosch,m_can.yaml#/properties/bosch,mram-cfg
Any hints to share a property?

-Texas Instruments TCAN4x5x CAN Controller
-================================================
-
-This file provides device node information for the TCAN4x5x interface contains.
-
-Required properties:
- - compatible:
- "ti,tcan4552", "ti,tcan4x5x"
- "ti,tcan4553", "ti,tcan4x5x" or
- "ti,tcan4x5x"
- - reg: 0
- - #address-cells: 1
- - #size-cells: 0
- - spi-max-frequency: Maximum frequency of the SPI bus the chip can
- operate at should be less than or equal to 18 MHz.
- - interrupt-parent: the phandle to the interrupt controller which provides
- the interrupt.
- - interrupts: interrupt specification for data-ready.
-
-See Documentation/devicetree/bindings/net/can/bosch,m_can.yaml for additional
-required property details.
-
-Optional properties:
- - reset-gpios: Hardwired output GPIO. If not defined then software
- reset.
- - device-state-gpios: Input GPIO that indicates if the device is in
- a sleep state or if the device is active. Not
- available with tcan4552/4553.
- - device-wake-gpios: Wake up GPIO to wake up the TCAN device. Not
- available with tcan4552/4553.
- - wakeup-source: Leave the chip running when suspended, and configure
- the RX interrupt to wake up the device.
-
-Example:
-tcan4x5x: tcan4x5x@0 {
- compatible = "ti,tcan4x5x";
- reg = <0>;
- #address-cells = <1>;
- #size-cells = <1>;
- spi-max-frequency = <10000000>;
- bosch,mram-cfg = <0x0 0 0 16 0 0 1 1>;
- interrupt-parent = <&gpio1>;
- interrupts = <14 IRQ_TYPE_LEVEL_LOW>;
- device-state-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>;
- device-wake-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
- reset-gpios = <&gpio1 27 GPIO_ACTIVE_HIGH>;
- wakeup-source;
-};
