1674 The following two properties are deprecated. rx-clock has been replaced
1675 with rx-clock-name, and tx-clock has been replaced with tx-clock-name.
1676 Drivers that currently use the deprecated properties should continue to
1677 do so, in order to support older device trees, but they should be updated
1678 to check for the new properties first.

1848
1849 viii) Uploaded QE firmware
1850
1851 If a new firwmare has been uploaded to the QE (usually by the
1852 boot loader), then a 'firmware' child node should be added to the QE
1853 node. This node provides information on the uploaded firmware that
1854 device drivers may need.
1855
1856 Required properties:
1857 - id: The string name of the firmware. This is taken from the 'id'

2129 viii) Multi-User RAM (MURAM)
2130
2131 The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
2132
2133 Ranges must be set up subject to the following restrictions:
2134
2135 - Children's reg nodes must be offsets from the start of all muram, even
2136 if the user-data area does not begin at zero.
2137 - If multiple range entries are used, the difference between the parent
2138 address and the child address must be the same in all, so that a single
2139 mapping can cover them all while maintaining the ability to determine
2140 CPM-side offsets with pointer subtraction. It is recommended that
2141 multiple range entries not be used.
2142 - A child address of zero must be translatable, even if no reg resources
2143 contain it.
2144
2145 A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
2146 indicate the portion of muram that is usable by the OS for arbitrary
2147 purposes. The data node may have an arbitrary number of reg resources,
2148 all of which contribute to the allocatable muram pool.
2149
2150 Example, based on mpc8272:
2151
2152 muram@0 {
2153 #address-cells = <1>;
2154 #size-cells = <1>;
2155 ranges = <0 0 10000>;
2156
2157 data@0 {
2158 compatible = "fsl,cpm-muram-data";
2159 reg = <0 2000 9800 800>;
2160 };
2161 };
2162
2163 x) I2C
2164
2165 The I2C controller is expressed as a bus under the CPM node.
2166
2167 Properties:
2168 - compatible : "fsl,cpm1-i2c", "fsl,cpm2-i2c"
2169 - reg : On CPM2 devices, the second resource doesn't specify the I2C
2170 Parameter RAM itself, but the I2C_BASE field of the CPM2 Parameter RAM
2171 (typically 0x8afc 0x2).
2172 - #address-cells : Should be one. The cell is the i2c device address with
2173 the r/w bit set to zero.
2174 - #size-cells : Should be zero.
2175 - clock-frequency : Can be used to set the i2c clock frequency. If
2176 unspecified, a default frequency of 60kHz is being used.
2177 The following two properties are deprecated. They are only used by legacy
2178 i2c drivers to find the bus to probe:
2179 - linux,i2c-index : Can be used to hard code an i2c bus number. By default,
2180 the bus number is dynamically assigned by the i2c core.
2181 - linux,i2c-class : Can be used to override the i2c class. The class is used
2182 by legacy i2c device drivers to find a bus in a specific context like
2183 system management, video or sound. By default, I2C_CLASS_HWMON (1) is
2184 being used. The definition of the classes can be found in
2185 include/i2c/i2c.h
2186
2187 Example, based on mpc823:
2188
2189 i2c@860 {
2190 compatible = "fsl,mpc823-i2c",
2191 "fsl,cpm1-i2c";
2192 reg = <0x860 0x20 0x3c80 0x30>;

2194 interrupt-parent = <&CPM_PIC>;
2195 fsl,cpm-command = <0x10>;
2196 #address-cells = <1>;
2197 #size-cells = <0>;
2198
2199 rtc@68 {

2201 reg = <0x68>;
2202 };
2203 };
2204
2205 m) Chipselect/Local Bus
2206
2207 Properties:
2208 - name : Should be localbus
2209 - #address-cells : Should be either two or three. The first cell is the
2210 chipselect number, and the remaining cells are the
2211 offset into the chipselect.
2212 - #size-cells : Either one or two, depending on how large each chipselect
2213 can be.
2214 - ranges : Each range corresponds to a single chipselect, and cover
2215 the entire access window as configured.
2216
2217 Example:
2218 localbus@f0010100 {
2219 compatible = "fsl,mpc8272-localbus",
2220 "fsl,pq2-localbus";

8
9Properties:

22* Properties common to mulitple CPM/QE devices
23
24- fsl,cpm-command : This value is ORed with the opcode and command flag
25 to specify the device on which a CPM command operates.
26
27- fsl,cpm-brg : Indicates which baud rate generator the device
28 is associated with. If absent, an unused BRG
29 should be dynamically allocated. If zero, the
30 device uses an external clock rather than a BRG.
31
32- reg : Unless otherwise specified, the first resource represents the
33 scc/fcc/ucc registers, and the second represents the device's
34 parameter RAM region (if it has one).
35
36* Multi-User RAM (MURAM)
37
38The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
39
40Ranges must be set up subject to the following restrictions:
41
42- Children's reg nodes must be offsets from the start of all muram, even
43 if the user-data area does not begin at zero.
44- If multiple range entries are used, the difference between the parent
45 address and the child address must be the same in all, so that a single
46 mapping can cover them all while maintaining the ability to determine
47 CPM-side offsets with pointer subtraction. It is recommended that
48 multiple range entries not be used.
49- A child address of zero must be translatable, even if no reg resources
50 contain it.
51
52A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
53indicate the portion of muram that is usable by the OS for arbitrary
54purposes. The data node may have an arbitrary number of reg resources,
55all of which contribute to the allocatable muram pool.
56
57Example, based on mpc8272:
58 muram@0 {
59 #address-cells = <1>;
60 #size-cells = <1>;
61 ranges = <0 0 10000>;

17- linux,i2c-index : Can be used to hard code an i2c bus number. By default,
18 the bus number is dynamically assigned by the i2c core.
19- linux,i2c-class : Can be used to override the i2c class. The class is used
20 by legacy i2c device drivers to find a bus in a specific context like
21 system management, video or sound. By default, I2C_CLASS_HWMON (1) is
22 being used. The definition of the classes can be found in
23 include/i2c/i2c.h

4NOTE: This is an interim binding; it should be updated to fit
5in with the CPM binding later in this document.
6
7Basically, it is a bus of devices, that could act more or less
8as a complete entity (UCC, USB etc ). All of them should be siblings on
9the "root" qe node, using the common properties from there.

1* Uploaded QE firmware
2
3 If a new firwmare 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

1* Parallel I/O Ports
2
3This node configures Parallel I/O ports for CPUs with QE support.
4The node should reside in the "soc" node of the tree. For each
5device that using parallel I/O ports, a child node should be created.
6See the definition of the Pin configuration nodes below for more
7information.
8
9Required properties:
10- device_type : should be "par_io".
11- reg : offset to the register set and its length.
12- num-ports : number of Parallel I/O ports
13
14Example:
15par_io@1400 {
16 reg = <1400 100>;
17 #address-cells = <1>;
18 #size-cells = <0>;
19 device_type = "par_io";
20 num-ports = <7>;
21 ucc_pin@01 {
22 ......
23 };
24
25Note that "par_io" nodes are obsolete, and should not be used for
26the new device trees. Instead, each Par I/O bank should be represented
27via its own gpio-controller node:
28
29Required properties:

16 3 = The pin is I/O
17
18 - open_drain : indicates the pin is normal or wired-OR:
19
20 0 = The pin is actively driven as an output
21 1 = The pin is an open-drain driver. As an output, the pin is
22 driven active-low, otherwise it is three-stated.

24 - assignment : function number of the pin according to the Pin Assignment
25 tables in User Manual. Each pin can have up to 4 possible functions in
26 QE and two options for CPM.
27 - has_irq : indicates if the pin is used as source of external
28 interrupts.

1* UCC (Unified Communications Controllers)
2
3Required properties:
4- device_type : should be "network", "hldc", "uart", "transparent"
5 "bisync", "atm", or "serial".
6- compatible : could be "ucc_geth" or "fsl_atm" and so on.
7- cell-index : the ucc number(1-8), corresponding to UCCx in UM.
8- reg : Offset and length of the register set for the device
9- interrupts : <a b> where a is the interrupt number and b is a
10 field that represents an encoding of the sense and level
11 information for the interrupt. This should be encoded based on
12 the information in section 2) depending on the type of interrupt
13 controller you have.
14- interrupt-parent : the phandle for the interrupt controller that
15 services interrupts for this device.
16- pio-handle : The phandle for the Parallel I/O port configuration.
17- port-number : for UART drivers, the port number to use, between 0 and 3.
18 This usually corresponds to the /dev/ttyQE device, e.g. <0> = /dev/ttyQE0.
19 The port number is added to the minor number of the device. Unlike the
20 CPM UART driver, the port-number is required for the QE UART driver.
21- soft-uart : for UART drivers, if specified this means the QE UART device
22 driver should use "Soft-UART" mode, which is needed on some SOCs that have
23 broken UART hardware. Soft-UART is provided via a microcode upload.
24- rx-clock-name: the UCC receive clock source
25 "none": clock source is disabled
26 "brg1" through "brg16": clock source is BRG1-BRG16, respectively
27 "clk1" through "clk24": clock source is CLK1-CLK24, respectively
28- tx-clock-name: the UCC transmit clock source
29 "none": clock source is disabled
30 "brg1" through "brg16": clock source is BRG1-BRG16, respectively
31 "clk1" through "clk24": clock source is CLK1-CLK24, respectively
32The following two properties are deprecated. rx-clock has been replaced
33with rx-clock-name, and tx-clock has been replaced with tx-clock-name.
34Drivers that currently use the deprecated properties should continue to
35do so, in order to support older device trees, but they should be updated
36to check for the new properties first.
37- rx-clock : represents the UCC receive clock source.
38 0x00 : clock source is disabled;
39 0x1~0x10 : clock source is BRG1~BRG16 respectively;
40 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
41- tx-clock: represents the UCC transmit clock source;
42 0x00 : clock source is disabled;
43 0x1~0x10 : clock source is BRG1~BRG16 respectively;
44 0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
45
46Required properties for network device_type:
47- mac-address : list of bytes representing the ethernet address.
48- phy-handle : The phandle for the PHY connected to this controller.
49
50Recommended properties:
51- phy-connection-type : a string naming the controller/PHY interface type,
52 i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id" (Internal
