1 * Freescale QUICC Engine module (QE)
2 This represents qe module that is installed on PowerQUICC II Pro.
4 NOTE: This is an interim binding; it should be updated to fit
5 in with the CPM binding later in this document.
7 Basically, it is a bus of devices, that could act more or less
8 as a complete entity (UCC, USB etc ). All of them should be siblings on
9 the "root" qe node, using the common properties from there.
10 The description below applies to the qe of MPC8360 and
11 more nodes and properties would be extended in the future.
16 - compatible : should be "fsl,qe";
17 - model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
18 - reg : offset and length of the device registers.
19 - bus-frequency : the clock frequency for QUICC Engine.
21 Recommended properties
22 - brg-frequency : the internal clock source frequency for baud-rate
29 #interrupt-cells = <2>;
30 compatible = "fsl,qe";
31 ranges = <0 e0100000 00100000>;
34 bus-frequency = <179A7B00>;
37 * Multi-User RAM (MURAM)
40 - compatible : should be "fsl,qe-muram", "fsl,cpm-muram".
41 - mode : the could be "host" or "slave".
42 - ranges : Should be defined as specified in 1) to describe the
43 translation of MURAM addresses.
44 - data-only : sub-node which defines the address area under MURAM
45 bus that can be allocated as data/parameter
50 compatible = "fsl,qe-muram", "fsl,cpm-muram";
51 ranges = <0 00010000 0000c000>;
54 compatible = "fsl,qe-muram-data",
