The node should be placed 19 inside a QE node that needs it. Doing so eliminates the need for a 20 fsl,firmware-phandle property. Other QE nodes that need the same firmware 21 should define an fsl,firmware-phandle property that points to the firmware node 22 in the first QE node. 23 24 The fsl,firmware property can be specified in the DTS (possibly using incbin) 25 or can be inserted by the boot loader at boot time. 26 27properties: 28 compatible: 29 enum: 30 - fsl,qe-firmware 31 32 fsl,firmware: 33 $ref: /schemas/types.yaml#/definitions/uint8-array 34 description: 35 A standard property.
