};
h) Board Control and Status (BCSR)
Required properties:
- device_type : Should be "board-control"
- reg : Offset and length of the register set for the device
Example:
bcsr@f8000000 {
device_type = "board-control";
reg = <f8000000 8000>;
};
i) Freescale QUICC Engine module (QE)
This represents qe module that is installed on PowerQUICC II Pro.
Hopefully it will merge backward compatibility with CPM/CPM2.
Basically, it is a bus of devices, that could act more or less
as a complete entity (UCC, USB etc ). All of them should be siblings on
the "root" qe node, using the common properties from there.
The description below applies to the the qe of MPC8360 and
more nodes and properties would be extended in the future.
i) Root QE device
Required properties:
- device_type : should be "qe";
- model : precise model of the QE, Can be "QE", "CPM", or "CPM2"
- reg : offset and length of the device registers.
- bus-frequency : the clock frequency for QUICC Engine.
Recommended properties
- brg-frequency : the internal clock source frequency for baud-rate
generators in Hz.
Example:
qe@e0100000 {
#address-cells = <1>;
#size-cells = <1>;
#interrupt-cells = <2>;
device_type = "qe";
model = "QE";
ranges = <0 e0100000 00100000>;
reg = <e0100000 480>;
brg-frequency = <0>;
bus-frequency = <179A7B00>;
}
ii) SPI (Serial Peripheral Interface)
Required properties:
- device_type : should be "spi".
- compatible : should be "fsl_spi".
- mode : the spi operation mode, it can be "cpu" or "qe".
- reg : Offset and length of the register set for the device
- interrupts : <a b> where a is the interrupt number and b is a
field that represents an encoding of the sense and level
information for the interrupt. This should be encoded based on
the information in section 2) depending on the type of interrupt
controller you have.
- interrupt-parent : the phandle for the interrupt controller that
services interrupts for this device.
Example:
spi@4c0 {
device_type = "spi";
compatible = "fsl_spi";
reg = <4c0 40>;
interrupts = <82 0>;
interrupt-parent = <700>;
mode = "cpu";
};
iii) USB (Universal Serial Bus Controller)
Required properties:
- device_type : should be "usb".
- compatible : could be "qe_udc" or "fhci-hcd".
- mode : the could be "host" or "slave".
- reg : Offset and length of the register set for the device
- interrupts : <a b> where a is the interrupt number and b is a
field that represents an encoding of the sense and level
information for the interrupt. This should be encoded based on
the information in section 2) depending on the type of interrupt
controller you have.
- interrupt-parent : the phandle for the interrupt controller that
services interrupts for this device.
Example(slave):
usb@6c0 {
device_type = "usb";
compatible = "qe_udc";
reg = <6c0 40>;
interrupts = <8b 0>;
interrupt-parent = <700>;
mode = "slave";
};
iv) UCC (Unified Communications Controllers)
Required properties:
- device_type : should be "network", "hldc", "uart", "transparent"
"bisync" or "atm".
- compatible : could be "ucc_geth" or "fsl_atm" and so on.
- model : should be "UCC".
- device-id : the ucc number(1-8), corresponding to UCCx in UM.
- reg : Offset and length of the register set for the device
- interrupts : <a b> where a is the interrupt number and b is a
field that represents an encoding of the sense and level
information for the interrupt. This should be encoded based on
the information in section 2) depending on the type of interrupt
controller you have.
- interrupt-parent : the phandle for the interrupt controller that
services interrupts for this device.
- pio-handle : The phandle for the Parallel I/O port configuration.
- rx-clock : represents the UCC receive clock source.
0x00 : clock source is disabled;
0x1~0x10 : clock source is BRG1~BRG16 respectively;
0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
- tx-clock: represents the UCC transmit clock source;
0x00 : clock source is disabled;
0x1~0x10 : clock source is BRG1~BRG16 respectively;
0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
Required properties for network device_type:
- mac-address : list of bytes representing the ethernet address.
- phy-handle : The phandle for the PHY connected to this controller.
Example:
ucc@2000 {
device_type = "network";
compatible = "ucc_geth";
model = "UCC";
device-id = <1>;
reg = <2000 200>;
interrupts = <a0 0>;
interrupt-parent = <700>;
mac-address = [ 00 04 9f 00 23 23 ];
rx-clock = "none";
tx-clock = "clk9";
phy-handle = <212000>;
pio-handle = <140001>;
};
v) Parallel I/O Ports
This node configures Parallel I/O ports for CPUs with QE support.
The node should reside in the "soc" node of the tree. For each
device that using parallel I/O ports, a child node should be created.
See the definition of the Pin configuration nodes below for more
information.
Required properties:
- device_type : should be "par_io".
- reg : offset to the register set and its length.
- num-ports : number of Parallel I/O ports
Example:
par_io@1400 {
reg = <1400 100>;
#address-cells = <1>;
#size-cells = <0>;
device_type = "par_io";
num-ports = <7>;
ucc_pin@01 {
......
};
vi) Pin configuration nodes
Required properties:
- linux,phandle : phandle of this node; likely referenced by a QE
device.
- pio-map : array of pin configurations. Each pin is defined by 6
integers. The six numbers are respectively: port, pin, dir,
open_drain, assignment, has_irq.
- port : port number of the pin; 0-6 represent port A-G in UM.
- pin : pin number in the port.
- dir : direction of the pin, should encode as follows:
0 = The pin is disabled
1 = The pin is an output
2 = The pin is an input
3 = The pin is I/O
- open_drain : indicates the pin is normal or wired-OR:
0 = The pin is actively driven as an output
1 = The pin is an open-drain driver. As an output, the pin is
driven active-low, otherwise it is three-stated.
- assignment : function number of the pin according to the Pin Assignment
tables in User Manual. Each pin can have up to 4 possible functions in
QE and two options for CPM.
- has_irq : indicates if the pin is used as source of exteral
interrupts.
Example:
ucc_pin@01 {
linux,phandle = <140001>;
pio-map = <
/* port pin dir open_drain assignment has_irq */
0 3 1 0 1 0 /* TxD0 */

2 9 1 0 3 0 /* GTX_CLK - CLK10 */
2 8 2 0 1 0>; /* GTX125 - CLK9 */
};
vii) Multi-User RAM (MURAM)
Required properties:
- device_type : should be "muram".
- mode : the could be "host" or "slave".
- ranges : Should be defined as specified in 1) to describe the
translation of MURAM addresses.
- data-only : sub-node which defines the address area under MURAM
bus that can be allocated as data/parameter
Example:
muram@10000 {
device_type = "muram";
ranges = <0 00010000 0000c000>;
data-only@0{
reg = <0 c000>;
};
};
More devices will be defined as this spec matures.

* higher level bits

* 70-7f C0 ** ** 00 - C0 ** ** 0f IPI
* The bottom 8 bits are split into 2 type bits and 6 data bits that
* depend on the type:
*
* F flags
* C class
* S source
* P Priority
* + node number
* * don't care
* 00 (0x00 | data) : normal interrupt. data is (class << 4) | source
* 01 (0x40 | data) : IO exception. data is the exception number as
* defined by bit numbers in IIC_SR
* 10 (0x80 | data) : IPI. data is the IPI number (obtained from the priority)
* and node is always 0 (IPIs are per-cpu, their source is
* not relevant)
* 11 (0xc0 | data) : reserved
*
* A node consists of a Cell Broadband Engine and an optional
* south bridge device providing a maximum of 64 IRQs.
* The south bridge may be connected to either IOIF0
* or IOIF1.
* Each SPE is represented as three IRQ lines, one per
* interrupt class.
* 16 IRQ numbers are reserved for inter processor
* interruptions, although these are only used in the
* range of the first node.
* In addition, interrupt number 0x80000000 is defined as always invalid
* (that is the node field is expected to never extend to move than 23 bits)
*
* This scheme needs 128 IRQ numbers per BIF node ID,
* which means that with the total of 512 lines
* available, we can have a maximum of four nodes.
