    1 * Uploaded QE firmware
    2 
    3       If a new firmware has been uploaded to the QE (usually by the
    4       boot loader), then a 'firmware' child node should be added to the QE
    5       node.  This node provides information on the uploaded firmware that
    6       device drivers may need.
    7 
    8       Required properties:
    9       - id: The string name of the firmware.  This is taken from the 'id'
   10             member of the qe_firmware structure of the uploaded firmware.
   11             Device drivers can search this string to determine if the
   12             firmware they want is already present.
   13       - extended-modes: The Extended Modes bitfield, taken from the
   14                    firmware binary.  It is a 64-bit number represented
   15                    as an array of two 32-bit numbers.
   16       - virtual-traps: The virtual traps, taken from the firmware binary.
   17                   It is an array of 8 32-bit numbers.
   18 
   19 Example:
   20         firmware {
   21                 id = "Soft-UART";
   22                 extended-modes = <0 0>;
   23                 virtual-traps = <0 0 0 0 0 0 0 0>;
   24         };
