It is possible to de-authorize devices by writing ``0`` to their

When a device is de-authorized the PCIe tunnel from the parent device

down. This is essentially the same thing as PCIe hot-remove and the PCIe

Workqueue Concurrency
=====================
XFS uses kernel workqueues to parallelize metadata update processes. This
enables it to take advantage of storage hardware that can service many IO
operations simultaneously. This interface exposes internal implementation
details of XFS, and as such is explicitly not part of any userspace API/ABI
guarantee the kernel may give userspace. These are undocumented features of
the generic workqueue implementation XFS uses for concurrency, and they are
provided here purely for diagnostic and tuning purposes and may change at any
time in the future.
The control knobs for a filesystem's workqueues are organized by task at hand
and the short name of the data device. They all can be found in:

For various board the "board" node may contain specific properties
that pertain to this particular board, such as board-specific GPIOs
or board power regulator supplies.
Required root node property:
compatible="stericsson,u300";
Required node: syscon
This contains the system controller.
- compatible: must be "stericsson,u300-syscon".
- reg: the base address and size of the system controller.
Boards with the U300 SoC include:
S365 "Small Board U365":
Required node: s365
This contains the board-specific information.
- compatible: must be "stericsson,s365".
- vana15-supply: the regulator supplying the 1.5V to drive the
board.
- syscon: a pointer to the syscon node so we can access the
syscon registers to set the board as self-powered.
Example:
/ {
model = "ST-Ericsson U300";

C6X PLL Clock Controllers
-------------------------
This is a first-cut support for the SoC clock controllers. This is still
under development and will probably change as the common device tree
clock support is added to the kernel.
Required properties:
- compatible: "ti,c64x+pll"
May also have SoC-specific value to support SoC-specific initialization
in the driver. One of:
"ti,c6455-pll"
"ti,c6457-pll"
"ti,c6472-pll"
"ti,c6474-pll"
- reg: base address and size of register area
- clock-frequency: input clock frequency in hz
Optional properties:
- ti,c64x+pll-bypass-delay: CPU cycles to delay when entering bypass mode
- ti,c64x+pll-reset-delay: CPU cycles to delay after PLL reset
- ti,c64x+pll-lock-delay: CPU cycles to delay after PLL frequency change
Example:
clock-controller@29a0000 {
compatible = "ti,c6472-pll", "ti,c64x+pll";
reg = <0x029a0000 0x200>;

Device State Configuration Registers
------------------------------------
TI C6X SoCs contain a region of miscellaneous registers which provide various
function for SoC control or status. Details vary considerably among from SoC
to SoC with no two being alike.
In general, the Device State Configuration Registers (DSCR) will provide one or
more configuration registers often protected by a lock register where one or
more key values must be written to a lock register in order to unlock the
configuration register for writes. These configuration register may be used to
enable (and disable in some cases) SoC pin drivers, select peripheral clock
sources (internal or pin), etc. In some cases, a configuration register is
write once or the individual bits are write once. In addition to device config,
the DSCR block may provide registers which are used to reset peripherals,
provide device ID information, provide ethernet MAC addresses, as well as other
miscellaneous functions.
For device state control (enable/disable), each device control is assigned an
id which is used by individual device drivers to control the state as needed.
Required properties:
- compatible: must be "ti,c64x+dscr"
- reg: register area base and size
Optional properties:
NOTE: These are optional in that not all SoCs will have all properties. For
SoCs which do support a given property, leaving the property out of the
device tree will result in reduced functionality or possibly driver
failure.
- ti,dscr-devstat
offset of the devstat register
- ti,dscr-silicon-rev
offset, start bit, and bitsize of silicon revision field
- ti,dscr-rmii-resets
offset and bitmask of RMII reset field. May have multiple tuples if more
than one ethernet port is available.
- ti,dscr-locked-regs
possibly multiple tuples describing registers which are write protected by
a lock register. Each tuple consists of the register offset, lock register
offsset, and the key value used to unlock the register.
- ti,dscr-kick-regs
offset and key values of two "kick" registers used to write protect other
registers in DSCR. On SoCs using kick registers, the first key must be
written to the first kick register and the second key must be written to
the second register before other registers in the area are write-enabled.
- ti,dscr-mac-fuse-regs
MAC addresses are contained in two registers. Each element of a MAC address
is contained in a single byte. This property has two tuples. Each tuple has
a register offset and four cells representing bytes in the register from
most significant to least. The value of these four cells is the MAC byte
index (1-6) of the byte within the register. A value of 0 means the byte
is unused in the MAC address.
- ti,dscr-devstate-ctl-regs
This property describes the bitfields used to control the state of devices.
Each tuple describes a range of identical bitfields used to control one or
more devices (one bitfield per device). The layout of each tuple is:
start_id num_ids reg enable disable start_bit nbits
Where:
start_id is device id for the first device control in the range
num_ids is the number of device controls in the range
reg is the offset of the register holding the control bits
enable is the value to enable a device
disable is the value to disable a device (0xffffffff if cannot disable)
start_bit is the bit number of the first bit in the range
nbits is the number of bits per device control
- ti,dscr-devstate-stat-regs
This property describes the bitfields used to provide device state status
for device states controlled by the DSCR. Each tuple describes a range of
identical bitfields used to provide status for one or more devices (one
bitfield per device). The layout of each tuple is:
start_id num_ids reg enable disable start_bit nbits
Where:
start_id is device id for the first device status in the range
num_ids is the number of devices covered by the range
reg is the offset of the register holding the status bits
enable is the value indicating device is enabled
disable is the value indicating device is disabled
start_bit is the bit number of the first bit in the range
nbits is the number of bits per device status
- ti,dscr-privperm
Offset and default value for register used to set access privilege for
some SoC devices.
Example:
device-state-config-regs@2a80000 {
compatible = "ti,c64x+dscr";
reg = <0x02a80000 0x41000>;
ti,dscr-devstat = <0>;
ti,dscr-silicon-rev = <8 28 0xf>;
ti,dscr-rmii-resets = <0x40020 0x00040000>;

External Memory Interface
-------------------------
The emifa node describes a simple external bus controller found on some C6X
SoCs. This interface provides external busses with a number of chip selects.
Required properties:
- compatible: must be "ti,c64x+emifa", "simple-bus"
- reg: register area base and size
- #address-cells: must be 2 (chip-select + offset)
- #size-cells: must be 1
- ranges: mapping from EMIFA space to parent space
Optional properties:
- ti,dscr-dev-enable: Device ID if EMIF is enabled/disabled from DSCR
- ti,emifa-burst-priority:
Number of memory transfers after which the EMIF will elevate the priority
of the oldest command in the command FIFO. Setting this field to 255
disables this feature, thereby allowing old commands to stay in the FIFO
indefinitely.
- ti,emifa-ce-config:
Configuration values for each of the supported chip selects.
Example:

Invensense MPU-3050 Gyroscope device tree bindings
Required properties:
- compatible : should be "invensense,mpu3050"
- reg : the I2C address of the sensor
Optional properties:
- interrupts : interrupt mapping for the trigger interrupt from the
internal oscillator. The following IRQ modes are supported:
IRQ_TYPE_EDGE_RISING, IRQ_TYPE_EDGE_FALLING, IRQ_TYPE_LEVEL_HIGH and
IRQ_TYPE_LEVEL_LOW. The driver should detect and configure the hardware
for the desired interrupt type.
- vdd-supply : supply regulator for the main power voltage.
- vlogic-supply : supply regulator for the signal voltage.
- mount-matrix : see iio/mount-matrix.txt
Optional subnodes:
- The MPU-3050 will pass through and forward the I2C signals from the
incoming I2C bus, alternatively drive traffic to a slave device (usually
an accelerometer) on its own initiative. Therefore is supports a subnode
i2c gate node. For details see: i2c/i2c-gate.txt
Example:
mpu3050@68 {
compatible = "invensense,mpu3050";
reg = <0x68>;
interrupt-parent = <&foo>;
interrupts = <12 IRQ_TYPE_EDGE_FALLING>;
vdd-supply = <&bar>;
vlogic-supply = <&baz>;
/* External I2C interface */
i2c-gate {
#address-cells = <1>;
#size-cells = <0>;
fnord@18 {
compatible = "fnord";
reg = <0x18>;
interrupt-parent = <&foo>;
interrupts = <13 IRQ_TYPE_EDGE_FALLING>;
};
};

"invensense,icm20690"
"invensense,iam20680"
- reg : the I2C address of the sensor
- interrupts: interrupt mapping for IRQ. It should be configured with flags
IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
IRQ_TYPE_EDGE_FALLING.
Refer to interrupt-controller/interrupts.txt for generic interrupt client node
bindings.
Optional properties:
- vdd-supply: regulator phandle for VDD supply
- vddio-supply: regulator phandle for VDDIO supply
- mount-matrix: an optional 3x3 mounting rotation matrix
- i2c-gate node. These devices also support an auxiliary i2c bus. This is
simple enough to be described using the i2c-gate binding. See
i2c/i2c-gate.txt for more details.

C6X Interrupt Chips
-------------------
* C64X+ Core Interrupt Controller
The core interrupt controller provides 16 prioritized interrupts to the
C64X+ core. Priority 0 and 1 are used for reset and NMI respectively.
Priority 2 and 3 are reserved. Priority 4-15 are used for interrupt
sources coming from outside the core.
Required properties:
--------------------
- compatible: Should be "ti,c64x+core-pic";
- #interrupt-cells: <1>
Interrupt Specifier Definition
------------------------------
Single cell specifying the core interrupt priority level (4-15) where
4 is highest priority and 15 is lowest priority.
Example
-------
core_pic: interrupt-controller@0 {
interrupt-controller;
#interrupt-cells = <1>;
compatible = "ti,c64x+core-pic";
};
* C64x+ Megamodule Interrupt Controller
The megamodule PIC consists of four interrupt mupliplexers each of which
combine up to 32 interrupt inputs into a single interrupt output which
may be cascaded into the core interrupt controller. The megamodule PIC
has a total of 12 outputs cascading into the core interrupt controller.
One for each core interrupt priority level. In addition to the combined
interrupt sources, individual megamodule interrupts may be cascaded to
the core interrupt controller. When an individual interrupt is cascaded,
it is no longer handled through a megamodule interrupt combiner and is
considered to have the core interrupt controller as the parent.
Required properties:
--------------------
- compatible: "ti,c64x+megamod-pic"
- interrupt-controller
- #interrupt-cells: <1>
- reg: base address and size of register area
- interrupts: This should have four cells; one for each interrupt combiner.
The cells contain the core priority interrupt to which the
corresponding combiner output is wired.
Optional properties:
--------------------
- ti,c64x+megamod-pic-mux: Array of 12 cells correspnding to the 12 core
priority interrupts. The first cell corresponds to
core priority 4 and the last cell corresponds to
core priority 15. The value of each cell is the
megamodule interrupt source which is MUXed to
the core interrupt corresponding to the cell
position. Allowed values are 4 - 127. Mapping for
interrupts 0 - 3 (combined interrupt sources) are
ignored.
Interrupt Specifier Definition
------------------------------
Single cell specifying the megamodule interrupt source (4-127). Note that
interrupts mapped directly to the core with "ti,c64x+megamod-pic-mux" will
use the core interrupt controller as their parent and the specifier will
be the core priority level, not the megamodule interrupt number.
Examples
--------
megamod_pic: interrupt-controller@1800000 {
compatible = "ti,c64x+megamod-pic";
interrupt-controller;
#interrupt-cells = <1>;
reg = <0x1800000 0x1000>;
interrupt-parent = <&core_pic>;
interrupts = < 12 13 14 15 >;
};
This is a minimal example where all individual interrupts go through a
combiner. Combiner-0 is mapped to core interrupt 12, combiner-1 is mapped
to interrupt 13, etc.
megamod_pic: interrupt-controller@1800000 {
compatible = "ti,c64x+megamod-pic";
interrupt-controller;
#interrupt-cells = <1>;
reg = <0x1800000 0x1000>;
interrupt-parent = <&core_pic>;
interrupts = < 12 13 14 15 >;
ti,c64x+megamod-pic-mux = < 0 0 0 0
32 0 0 0
0 0 0 0 >;
};
This the same as the first example except that megamodule interrupt 32 is
mapped directly to core priority interrupt 8. The node using this interrupt
must set the core controller as its interrupt parent and use 8 in the
interrupt specifier value.
