* Power State Coordination Interface (PSCI)
|
||||
|
||||
Firmware implementing the PSCI functions described in ARM document number
|
||||
ARM DEN 0022A ("Power State Coordination Interface System Software on ARM
|
||||
processors") can be used by Linux to initiate various CPU-centric power
|
||||
operations.
|
||||
|
||||
Issue A of the specification describes functions for CPU suspend, hotplug
|
||||
and migration of secure software.
|
||||
|
||||
Functions are invoked by trapping to the privilege level of the PSCI
|
||||
firmware (specified as part of the binding below) and passing arguments
|
||||
in a manner similar to that specified by AAPCS:
|
||||
|
||||
r0 => 32-bit Function ID / return value
|
||||
{r1 - r3} => Parameters
|
||||
|
||||
Note that the immediate field of the trapping instruction must be set
|
||||
to #0.
|
||||
|
||||
|
||||
Main node required properties:
|
||||
|
||||
- compatible : should contain at least one of:
|
||||
|
||||
* "arm,psci" : For implementations complying to PSCI versions prior
|
||||
to 0.2.
|
||||
For these cases function IDs must be provided.
|
||||
|
||||
* "arm,psci-0.2" : For implementations complying to PSCI 0.2.
|
||||
Function IDs are not required and should be ignored by
|
||||
an OS with PSCI 0.2 support, but are permitted to be
|
||||
present for compatibility with existing software when
|
||||
"arm,psci" is later in the compatible list.
|
||||
|
||||
* "arm,psci-1.0" : For implementations complying to PSCI 1.0.
|
||||
PSCI 1.0 is backward compatible with PSCI 0.2 with
|
||||
minor specification updates, as defined in the PSCI
|
||||
specification[2].
|
||||
|
||||
- method : The method of calling the PSCI firmware. Permitted
|
||||
values are:
|
||||
|
||||
"smc" : SMC #0, with the register assignments specified
|
||||
in this binding.
|
||||
|
||||
"hvc" : HVC #0, with the register assignments specified
|
||||
in this binding.
|
||||
|
||||
Main node optional properties:
|
||||
|
||||
- cpu_suspend : Function ID for CPU_SUSPEND operation
|
||||
|
||||
- cpu_off : Function ID for CPU_OFF operation
|
||||
|
||||
- cpu_on : Function ID for CPU_ON operation
|
||||
|
||||
- migrate : Function ID for MIGRATE operation
|
||||
|
||||
Device tree nodes that require usage of PSCI CPU_SUSPEND function (ie idle
|
||||
state nodes, as per bindings in [1]) must specify the following properties:
|
||||
|
||||
- arm,psci-suspend-param
|
||||
Usage: Required for state nodes[1] if the corresponding
|
||||
idle-states node entry-method property is set
|
||||
to "psci".
|
||||
Value type: <u32>
|
||||
Definition: power_state parameter to pass to the PSCI
|
||||
suspend call.
|
||||
|
||||
Example:
|
||||
|
||||
Case 1: PSCI v0.1 only.
|
||||
|
||||
psci {
|
||||
compatible = "arm,psci";
|
||||
method = "smc";
|
||||
cpu_suspend = <0x95c10000>;
|
||||
cpu_off = <0x95c10001>;
|
||||
cpu_on = <0x95c10002>;
|
||||
migrate = <0x95c10003>;
|
||||
};
|
||||
|
||||
Case 2: PSCI v0.2 only
|
||||
|
||||
psci {
|
||||
compatible = "arm,psci-0.2";
|
||||
method = "smc";
|
||||
};
|
||||
|
||||
Case 3: PSCI v0.2 and PSCI v0.1.
|
||||
|
||||
A DTB may provide IDs for use by kernels without PSCI 0.2 support,
|
||||
enabling firmware and hypervisors to support existing and new kernels.
|
||||
These IDs will be ignored by kernels with PSCI 0.2 support, which will
|
||||
use the standard PSCI 0.2 IDs exclusively.
|
||||
|
||||
psci {
|
||||
compatible = "arm,psci-0.2", "arm,psci";
|
||||
method = "hvc";
|
||||
|
||||
cpu_on = < arbitrary value >;
|
||||
cpu_off = < arbitrary value >;
|
||||
|
||||
...
|
||||

Firmware implementing the PSCI functions described in ARM document number
|
||||
ARM DEN 0022A ("Power State Coordination Interface System Software on ARM
|
||||
processors") can be used by Linux to initiate various CPU-centric power
|
||||
operations.
|
||||
|
||||
Issue A of the specification describes functions for CPU suspend, hotplug
|
||||
and migration of secure software.
|
||||
|
||||
Functions are invoked by trapping to the privilege level of the PSCI
|
||||
firmware (specified as part of the binding below) and passing arguments
|
||||
in a manner similar to that specified by AAPCS:
|
||||
|
||||
r0 => 32-bit Function ID / return value
|
||||
{r1 - r3} => Parameters
|
||||
|
||||
Note that the immediate field of the trapping instruction must be set
|
||||
to #0.

- native-endian: Boolean; always use register accesses matched to the

endianness of the kernel binary (e.g. LE vmlinux -> readl/writel,

BE vmlinux -> ioread32be/iowrite32be). In this case no byteswaps

In such cases, little-endian is the preferred default, but it is not

a requirement. The of_device_is_big_endian() and of_fdt_is_big_endian()

helper functions do assume that little-endian is the default, because

|
||||
Both delay properties need to be a multiple of 100. They control the
|
||||
clock delay for external RGMII PHY. They do not apply to the internal
|
||||
PHY or external non-RGMII PHYs.
|
||||
|
||||
Optional properties for the following compatibles:
|
||||
- "allwinner,sun8i-h3-emac",
|
||||
- "allwinner,sun8i-v3s-emac":
|
||||

Required child node of emac:
|
||||
- mdio bus node: should be named mdio with compatible "snps,dwmac-mdio"
|
||||
|
||||
Required properties of the mdio node:
|
||||
- #address-cells: shall be 1
|
||||
- #size-cells: shall be 0
|
||||
|
||||
The device node referenced by "phy" or "phy-handle" must be a child node
|
||||
of the mdio node. See phy.txt for the generic PHY bindings.
|
||||
|
||||
The following compatibles require that the emac node have a mdio-mux child
|
||||
node called "mdio-mux":
|
||||
- "allwinner,sun8i-h3-emac"
|
||||
- "allwinner,sun8i-v3s-emac":
|
||||
Required properties for the mdio-mux node:
|
||||
- compatible = "allwinner,sun8i-h3-mdio-mux"
|
||||
- mdio-parent-bus: a phandle to EMAC mdio
|
||||
- one child mdio for the integrated mdio with the compatible
|
||||
"allwinner,sun8i-h3-mdio-internal"
|
||||
- one child mdio for the external mdio if present (V3s have none)
|
||||
Required properties for the mdio-mux children node:
|
||||
- reg: 1 for internal MDIO bus, 2 for external MDIO bus
|
||||
|
||||
The following compatibles require a PHY node representing the integrated
|
||||
PHY, under the integrated MDIO bus node if an mdio-mux node is used:
|
||||
- "allwinner,sun8i-h3-emac",
|
||||
- "allwinner,sun8i-v3s-emac":

- phy-mode: string, operation mode of the PHY interface. This is now a de-facto

Fixed link Device Tree binding
|
||||
------------------------------
|
||||
|
||||
Some Ethernet MACs have a "fixed link", and are not connected to a
|
||||
normal MDIO-managed PHY device. For those situations, a Device Tree
|
||||
binding allows to describe a "fixed link".
|
||||
|
||||
Such a fixed link situation is described by creating a 'fixed-link'
|
||||
sub-node of the Ethernet MAC device node, with the following
|
||||
properties:
|
||||
|
||||
* 'speed' (integer, mandatory), to indicate the link speed. Accepted
|
||||
values are 10, 100 and 1000
|
||||
* 'full-duplex' (boolean, optional), to indicate that full duplex is
|
||||
used. When absent, half duplex is assumed.
|
||||
* 'pause' (boolean, optional), to indicate that pause should be
|
||||
enabled.
|
||||
* 'asym-pause' (boolean, optional), to indicate that asym_pause should
|
||||
be enabled.
|
||||
* 'link-gpios' ('gpio-list', optional), to indicate if a gpio can be read
|
||||
to determine if the link is up.
|
||||
|
||||
Old, deprecated 'fixed-link' binding:
|
||||
|
||||
* A 'fixed-link' property in the Ethernet MAC node, with 5 cells, of the
|
||||
form <a b c d e> with the following accepted values:
|
||||
- a: emulated PHY ID, choose any but but unique to the all specified
|
||||
fixed-links, from 0 to 31
|
||||
- b: duplex configuration: 0 for half duplex, 1 for full duplex
|
||||
- c: link speed in Mbits/sec, accepted values are: 10, 100 and 1000
|
||||
- d: pause configuration: 0 for no pause, 1 for pause
|
||||
- e: asymmetric pause configuration: 0 for no asymmetric pause, 1 for
|
||||
asymmetric pause
|
||||
|
||||
Examples:
|
||||
|
||||
ethernet@0 {
|
||||
...
|
||||
fixed-link {
|
||||
speed = <1000>;
|

Common MDIO bus properties.
|
||||
|
||||
These are generic properties that can apply to any MDIO bus.
|
||||
|
||||
Optional properties:
|
||||
- reset-gpios: One GPIO that control the RESET lines of all PHYs on that MDIO
|
||||
bus.
|
||||
- reset-delay-us: RESET pulse width in microseconds.
|
||||
|
||||
A list of child nodes, one per device on the bus is expected. These
|
||||
should follow the generic phy.txt, or a device specific binding document.
|
||||
|
||||
The 'reset-delay-us' indicates the RESET signal pulse width in microseconds and
|
||||
applies to all PHY devices. It must therefore be appropriately determined based
|
||||
on all PHY requirements (maximum value of all per-PHY RESET pulse widths).
|
||||

|
||||
This example shows these optional properties, plus other properties

- interrupts : interrupt specifier for the sole interrupt.
|

- reg : The ID number for the phy, usually a small integer
|
||||
|
||||
Optional Properties:
|
||||
|
||||
- compatible: Compatible list, may contain
|
||||
"ethernet-phy-ieee802.3-c22" or "ethernet-phy-ieee802.3-c45" for
|
||||
PHYs that implement IEEE802.3 clause 22 or IEEE802.3 clause 45
|
||||
specifications. If neither of these are specified, the default is to
|
||||
assume clause 22.
|
||||
|
||||
If the PHY reports an incorrect ID (or none at all) then the
|
||||
"compatible" list may contain an entry with the correct PHY ID in the
|
||||
form: "ethernet-phy-idAAAA.BBBB" where
|
||||
AAAA - The value of the 16 bit Phy Identifier 1 register as
|
||||
4 hex digits. This is the chip vendor OUI bits 3:18
|
||||
BBBB - The value of the 16 bit Phy Identifier 2 register as
|

4 hex digits. This is the chip vendor OUI bits 19:24,
|
||||
followed by 10 bits of a vendor specific ID.
|
||||
|
||||
The compatible list should not contain other values than those
|
||||
listed here.
|
||||
|
||||
- max-speed: Maximum PHY supported speed (10, 100, 1000...)
|
||||
|
||||
- broken-turn-around: If set, indicates the PHY device does not correctly
|
||||
release the turn around line low at the end of a MDIO transaction.
|
||||
|
||||
- enet-phy-lane-swap: If set, indicates the PHY will swap the TX/RX lanes to
|
||||
compensate for the board being designed with the lanes swapped.
|
||||
|
||||
- enet-phy-lane-no-swap: If set, indicates that PHY will disable swap of the
|
||||
TX/RX lanes. This property allows the PHY to work correcly after e.g. wrong
|
||||
bootstrap configuration caused by issues in PCB layout design.
|

- eee-broken-10gkr:
|
||||
Mark the corresponding energy efficient ethernet mode as broken and
|
||||
request the ethernet to stop advertising it.
|
||||
|
||||
- phy-is-integrated: If set, indicates that the PHY is integrated into the same
|
||||
physical package as the Ethernet MAC. If needed, muxers should be configured
|
||||
to ensure the integrated PHY is used. The absence of this property indicates
|
||||
the muxers should be configured so that the external PHY is used.
|
||||
|
||||
- resets: The reset-controller phandle and specifier for the PHY reset signal.
|
||||
|
||||
- reset-names: Must be "phy" for the PHY reset signal.
|
||||
|
||||
- reset-gpios: The GPIO phandle and specifier for the PHY reset signal.
|
||||
|
||||
- reset-assert-us: Delay after the reset was asserted in microseconds.
|
||||
If this property is missing the delay will be skipped.
|
||||
|
||||
- reset-deassert-us: Delay after the reset was deasserted in microseconds.
|
||||
If this property is missing the delay will be skipped.
