VII - Specifying interrupt information for devices
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.
+
+ NOTE: This is an interim binding; it should be updated to fit
+ in with the CPM binding later in this document.
+
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.
Required properties:
- device_type : should be "spi".
- compatible : should be "fsl_spi".
- - mode : the SPI operation mode, it can be "cpu" or "qe".
+ - mode : the SPI operation mode, it can be "cpu" or "cpu-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
};
};
- j) Flash chip nodes
+ j) CFI or JEDEC memory-mapped NOR flash
Flash chips (Memory Technology Devices) are often used for solid state
file systems on embedded devices.
- Required properties:
-
- - device_type : has to be "rom"
- - compatible : Should specify what this flash device is compatible with.
- Currently, this is most likely to be "direct-mapped" (which
- corresponds to the MTD physmap mapping driver).
- - reg : Offset and length of the register set (or memory mapping) for
- the device.
- - bank-width : Width of the flash data bus in bytes. Required
- for the NOR flashes (compatible == "direct-mapped" and others) ONLY.
+ - compatible : should contain the specific model of flash chip(s)
+ used, if known, followed by either "cfi-flash" or "jedec-flash"
+ - reg : Address range of the flash chip
+ - bank-width : Width (in bytes) of the flash bank. Equal to the
+ device width times the number of interleaved chips.
+ - device-width : (optional) Width of a single flash chip. If
+ omitted, assumed to be equal to 'bank-width'.
+ - #address-cells, #size-cells : Must be present if the flash has
+ sub-nodes representing partitions (see below). In this case
+ both #address-cells and #size-cells must be equal to 1.
+
+ For JEDEC compatible devices, the following additional properties
+ are defined:
+
+ - vendor-id : Contains the flash chip's vendor id (1 byte).
+ - device-id : Contains the flash chip's device id (1 byte).
+
+ In addition to the information on the flash bank itself, the
+ device tree may optionally contain additional information
+ describing partitions of the flash address space. This can be
+ used on platforms which have strong conventions about which
+ portions of the flash are used for what purposes, but which don't
+ use an on-flash partition table such as RedBoot.
+
+ Each partition is represented as a sub-node of the flash device.
+ Each node's name represents the name of the corresponding
+ partition of the flash device.
+
+ Flash partitions
+ - reg : The partition's offset and size within the flash bank.
+ - label : (optional) The label / name for this flash partition.
+ If omitted, the label is taken from the node name (excluding
+ the unit address).
+ - read-only : (optional) This parameter, if present, is a hint to
+ Linux that this flash partition should only be mounted
+ read-only. This is usually used for flash partitions
+ containing early-boot firmware images or data which should not
+ be clobbered.
- Recommended properties :
-
- - partitions : Several pairs of 32-bit values where the first value is
- partition's offset from the start of the device and the second one is
- partition size in bytes with LSB used to signify a read only
- partition (so, the partition size should always be an even number).
- - partition-names : The list of concatenated zero terminated strings
- representing the partition names.
- - probe-type : The type of probe which should be done for the chip
- (JEDEC vs CFI actually). Valid ONLY for NOR flashes.
-
- Example:
+ Example:
- flash@ff000000 {
- device_type = "rom";
- compatible = "direct-mapped";
- probe-type = "CFI";
- reg = <ff000000 01000000>;
- bank-width = <4>;
- partitions = <00000000 00f80000
- 00f80000 00080001>;
- partition-names = "fs\0firmware";
- };
+ flash@ff000000 {

+ bank-width = <4>;
+ device-width = <1>;
+ #address-cells = <1>;

+ reg = <0 f80000>;
+ };
+ firmware@f80000 {
+ label ="firmware";
+ reg = <f80000 80000>;
+ read-only;
+ };
+ };
k) Global Utilities Block
fsl,has-rstcr;

+ NOTE: This is an interim binding, and will likely change slightly,
+ as more devices are supported. The QE bindings especially are
+ incomplete.
+
+ i) Root CPM node
+
+ Properties:
+ - compatible : "fsl,cpm1", "fsl,cpm2", or "fsl,qe".
+ - reg : A 48-byte region beginning with CPCR.

+ to specify the device on which a CPM command operates.
+
+ - fsl,cpm-brg : Indicates which baud rate generator the device

+ should be dynamically allocated. If zero, the
+ device uses an external clock rather than a BRG.
+

+ scc/fcc/ucc registers, and the second represents the device's
+ parameter RAM region (if it has one).

+ #size-cells = <0>;
+ fsl,mdio-pin = <12>;
+ fsl,mdc-pin = <13>;
+ };
+
+ v) Baud Rate Generators
+
+ Currently defined compatibles:
+ fsl,cpm-brg
+ fsl,cpm1-brg
+ fsl,cpm2-brg
+
+ Properties:
+ - reg : There may be an arbitrary number of reg resources; BRG
+ numbers are assigned to these in order.
+ - clock-frequency : Specifies the base frequency driving
+ the BRG.
+
+ Example:
+
+ brg@119f0 {
+ compatible = "fsl,mpc8272-brg",
+ "fsl,cpm2-brg",
+ "fsl,cpm-brg";
+ reg = <119f0 10 115f0 10>;
+ clock-frequency = <d#25000000>;
+ };
+
+ vi) Interrupt Controllers
+
+ Currently defined compatibles:
+ - fsl,cpm1-pic
+ - only one interrupt cell
+ - fsl,pq1-pic
+ - fsl,cpm2-pic
+ - second interrupt cell is level/sense:
+ - 2 is falling edge

+ interrupt-parent = <&PIC>;
+ fsl,cpm-command = <2e600000>;
+ };
+
+ viii) Multi-User RAM (MURAM)
+
+ The multi-user/dual-ported RAM is expressed as a bus under the CPM node.
+
+ Ranges must be set up subject to the following restrictions:
+
+ - Children's reg nodes must be offsets from the start of all muram, even
+ if the user-data area does not begin at zero.
+ - If multiple range entries are used, the difference between the parent
+ address and the child address must be the same in all, so that a single
+ mapping can cover them all while maintaining the ability to determine
+ CPM-side offsets with pointer subtraction. It is recommended that
+ multiple range entries not be used.
+ - A child address of zero must be translatable, even if no reg resources
+ contain it.
+
+ A child "data" node must exist, compatible with "fsl,cpm-muram-data", to
+ indicate the portion of muram that is usable by the OS for arbitrary
+ purposes. The data node may have an arbitrary number of reg resources,
+ all of which contribute to the allocatable muram pool.
+
+ Example, based on mpc8272:
+
+ muram@0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0 10000>;
+
+ data@0 {
+ compatible = "fsl,cpm-muram-data";
+ reg = <0 2000 9800 800>;
+ };
+ };
+
+ m) Chipselect/Local Bus
+
+ Properties:
+ - name : Should be localbus
+ - #address-cells : Should be either two or three. The first cell is the
+ chipselect number, and the remaining cells are the
+ offset into the chipselect.
+ - #size-cells : Either one or two, depending on how large each chipselect
+ can be.
+ - ranges : Each range corresponds to a single chipselect, and cover
+ the entire access window as configured.
+
+ Example:
+ localbus@f0010100 {
+ compatible = "fsl,mpc8272ads-localbus",
+ "fsl,mpc8272-localbus",
+ "fsl,pq2-localbus";
+ #address-cells = <2>;
+ #size-cells = <1>;
+ reg = <f0010100 40>;
+
+ ranges = <0 0 fe000000 02000000
+ 1 0 f4500000 00008000>;
+
+ flash@0,0 {
+ compatible = "jedec-flash";
+ reg = <0 0 2000000>;
+ bank-width = <4>;
+ device-width = <1>;
+ };
+
+ board-control@1,0 {
+ reg = <1 0 20>;
+ compatible = "fsl,mpc8272ads-bcsr";
+ };
+ };
+
- h) 4xx/Axon EMAC ethernet nodes
++ n) 4xx/Axon EMAC ethernet nodes
+
+ The EMAC ethernet controller in IBM and AMCC 4xx chips, and also
+ the Axon bridge. To operate this needs to interact with a ths
+ special McMAL DMA controller, and sometimes an RGMII or ZMII
+ interface. In addition to the nodes and properties described
+ below, the node for the OPB bus on which the EMAC sits must have a
+ correct clock-frequency property.
+
+ i) The EMAC node itself
+
+ Required properties:
+ - device_type : "network"
+
+ - compatible : compatible list, contains 2 entries, first is
+ "ibm,emac-CHIP" where CHIP is the host ASIC (440gx,
+ 405gp, Axon) and second is either "ibm,emac" or
+ "ibm,emac4". For Axon, thus, we have: "ibm,emac-axon",
+ "ibm,emac4"
+ - interrupts : <interrupt mapping for EMAC IRQ and WOL IRQ>
+ - interrupt-parent : optional, if needed for interrupt mapping
+ - reg : <registers mapping>

+ with this EMAC
+ - mal-rx-channel : 1 cell, index of the rx channel on McMAL associated
+ with this EMAC
+ - cell-index : 1 cell, hardware index of the EMAC cell on a given
+ ASIC (typically 0x0 and 0x1 for EMAC0 and EMAC1 on
+ each Axon chip)

+ - mal-burst-size : 1 cell, MAL burst size (used to calculate thresholds)
+ in bytes.
+ For Axon, 0x00000100 (I think ...)
+ - phy-mode : string, mode of operations of the PHY interface.

+ "tbi", "gmii", rtbi", "sgmii".
+ For Axon on CAB, it is "rgmii"
+ - mdio-device : 1 cell, required iff using shared MDIO registers
+ (440EP). phandle of the EMAC to use to drive the
+ MDIO lines for the PHY used by this EMAC.
+ - zmii-device : 1 cell, required iff connected to a ZMII. phandle of
+ the ZMII device node
+ - zmii-channel : 1 cell, required iff connected to a ZMII. Which ZMII
+ channel or 0xffffffff if ZMII is only used for MDIO.
+ - rgmii-device : 1 cell, required iff connected to an RGMII. phandle
+ of the RGMII device node.
+ For Axon: phandle of plb5/plb4/opb/rgmii
+ - rgmii-channel : 1 cell, required iff connected to an RGMII. Which
+ RGMII channel is used by this EMAC.
+ Fox Axon: present, whatever value is appropriate for each
+ EMAC, that is the content of the current (bogus) "phy-port"
+ property.
+
+ Recommended properties:
+ - linux,network-index : This is the intended "index" of this
+ network device. This is used by the bootwrapper to interpret
+ MAC addresses passed by the firmware when no information other
+ than indices is available to associate an address with a device.
+
+ Optional properties:
+ - phy-address : 1 cell, optional, MDIO address of the PHY. If absent,
+ a search is performed.
+ - phy-map : 1 cell, optional, bitmap of addresses to probe the PHY
+ for, used if phy-address is absent. bit 0x00000001 is
+ MDIO address 0.
+ For Axon it can be absent, thouugh my current driver
+ doesn't handle phy-address yet so for now, keep
+ 0x00ffffff in it.
+ - rx-fifo-size-gige : 1 cell, Rx fifo size in bytes for 1000 Mb/sec
+ operations (if absent the value is the same as

+ offload, phandle of the TAH device node.
+ - tah-channel : 1 cell, optional. If appropriate, channel used on the

+
+ Example:

+ device_type = "network";
+ compatible = "ibm,emac-440gp", "ibm,emac";
+ interrupt-parent = <&UIC1>;
+ interrupts = <1c 4 1d 4>;
+ reg = <40000800 70>;
+ local-mac-address = [00 04 AC E3 1B 1E];
+ mal-device = <&MAL0>;
+ mal-tx-channel = <0 1>;
+ mal-rx-channel = <0>;
+ cell-index = <0>;
+ max-frame-size = <5dc>;
+ rx-fifo-size = <1000>;

+
+ Required properties:
+ - device_type : "dma-controller"
+ - compatible : compatible list, containing 2 entries, first is
+ "ibm,mcmal-CHIP" where CHIP is the host ASIC (like

+ For Axon, "ibm,mcmal-axon","ibm,mcmal2"
+ - interrupts : <interrupt mapping for the MAL interrupts sources:
+ 5 sources: tx_eob, rx_eob, serr, txde, rxde>.
+ For Axon: This is _different_ from the current
+ firmware. We use the "delayed" interrupts for txeob
+ and rxeob. Thus we end up with mapping those 5 MPIC
+ interrupts, all level positive sensitive: 10, 11, 32,
+ 33, 34 (in decimal)
+ - dcr-reg : < DCR registers range >
+ - dcr-parent : if needed for dcr-reg
+ - num-tx-chans : 1 cell, number of Tx channels
+ - num-rx-chans : 1 cell, number of Rx channels
+
+ iii) ZMII node
+
+ Required properties:
+ - compatible : compatible list, containing 2 entries, first is
+ "ibm,zmii-CHIP" where CHIP is the host ASIC (like
+ EMAC) and the second is "ibm,zmii".
+ For Axon, there is no ZMII node.
+ - reg : <registers mapping>
+
+ iv) RGMII node
+
+ Required properties:
+ - compatible : compatible list, containing 2 entries, first is
+ "ibm,rgmii-CHIP" where CHIP is the host ASIC (like
+ EMAC) and the second is "ibm,rgmii".
+ For Axon, "ibm,rgmii-axon","ibm,rgmii"
+ - reg : <registers mapping>

+
More devices will be defined as this spec matures.
