12 description: |
13 This node defines a firmware binary that is embedded in the device tree, for
14 the purpose of passing the firmware from bootloader to the kernel, or from
15 the hypervisor to the guest.
16
17 The firmware node itself contains the firmware binary contents, a compatible
18 property, and any firmware-specific properties. 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
27 properties:
28 compatible:
29 enum:
30 - fsl,qe-firmware

32 fsl,firmware:

35 A standard property. This property contains the firmware binary "blob".
