Description:
|

(RW) The Intel platform implementation of firmware activate
|
||||
support exposes an option let the platform force idle devices in
|
||||
the system over the activation event, or trust that the OS will
|
||||
do it. The safe default is to let the platform force idle
|
||||
devices since the kernel is already in a suspend state, and on
|
||||
the chance that a driver does not properly quiesce bus-mastering
|
||||
after a suspend callback the platform will handle it. However,
|
||||
the activation might abort if, for example, platform firmware
|
||||
determines that the activation time exceeds the max PCI-E
|
||||
completion timeout. Since the platform does not know whether the
|
||||
OS is running the activation from a suspend context it aborts,
|
||||
but if the system owner trusts driver suspend callback to be
|
||||
sufficient then 'firmware_activation_noidle' can be
|
||||
enabled to bypass the activation abort.

Operation Modes
|
||||
===============
|
||||
|
||||
``intel_pstate`` can operate in three different modes: in the active mode with
|
||||
or without hardware-managed P-states support and in the passive mode. Which of
|
||||
them will be in effect depends on what kernel command line options are used and
|
||||
on the capabilities of the processor.
|
||||
``intel_pstate`` can operate in two different modes, active or passive. In the
|
||||
active mode, it uses its own internal performance scaling governor algorithm or
|
||||
allows the hardware to do preformance scaling by itself, while in the passive
|
||||
mode it responds to requests made by a generic ``CPUFreq`` governor implementing
|
||||
a certain performance scaling algorithm. Which of them will be in effect
|

depends on what kernel command line options are used and on the capabilities of

Note that compaction has a non-trivial system-wide impact as pages

to latency spikes in unsuspecting applications. The kernel employs

various heuristics to avoid wasting CPU cycles if it detects that

If you need to change the pointer associated with an ID, you can call

ID by passing a ``NULL`` pointer to the allocation function; initialise the

Some users need to allocate IDs larger than ``INT_MAX``. So far all of

we will work with you to address your needs.

:c:func:`idr_alloc_cyclic`. The IDR becomes less efficient when dealing

either use the callback-based :c:func:`idr_for_each` or the

The TI K3 family of SoCs usually have a central System Controller Processor
|
||||
that is responsible for managing various SoC-level resources like clocks,
|
||||
resets, interrupts etc. The communication with that processor is performed
|
||||
through the TI-SCI protocol.
|
||||
|
||||
Each specific device management node like a clock controller node, a reset
|
||||
controller node or an interrupt-controller node should define a common set
|
||||
of properties that enables them to implement the corresponding functionality
|
||||
over the TI-SCI protocol. The following are some of the common properties
|
||||
needed by such individual nodes. The required properties for each device
|
||||
management node is defined in the respective binding.

Binding for IDT VersaClock 5,6 programmable i2c clock generators.
|
||||
|
||||
The IDT VersaClock 5 and VersaClock 6 are programmable i2c clock
|
||||
generators providing from 3 to 12 output clocks.
|
||||
|
||||
==I2C device node==
|
||||
|
||||
Required properties:
|
||||
- compatible: shall be one of
|

- #clock-cells: from common clock binding; shall be set to 1.
|
||||
- clocks: from common clock binding; list of parent clock handles,
|
||||
- 5p49v5923 and
|
||||
5p49v5925 and
|
||||
5p49v6901: (required) either or both of XTAL or CLKIN
|
||||

|
||||
- 5p49v5933 and
|
||||
- 5p49v5935: (optional) property not present (internal
|
||||

|
||||
clock.
|
||||
- clock-names: from common clock binding; clock input names, can be
|
||||
- 5p49v5923 and

0 -- OUT0_SEL_I2CB
|
||||
1 -- OUT1
|
||||
2 -- OUT4

||||
|
||||
5P49V5925 and
|
||||
5P49V5935:
|
||||
0 -- OUT0_SEL_I2CB
|
||||
1 -- OUT1
|
||||
2 -- OUT2
