|

This binding file is a collection of the LVDS panels that
|
||||
has dual LVDS ports and requires only a single power-supply.
|
||||
The first port receives odd pixels, and the second port receives even pixels.
|
||||
There are optionally a backlight and an enable GPIO.
|
||||
The panel may use an OF graph binding for the association to the display,
|
||||
or it may be a direct child node of the display.
|
||||
|
||||
If the panel is more advanced a dedicated binding file is required.

operating system shall exclude reserved memory from normal usage one can

create child nodes describing particular reserved (excluded from normal use)

memory regions. Such memory regions are usually designed for the special

usage by various device drivers.
|

|

Each child of the reserved-memory node specifies one or more regions
|

of reserved memory. Each child node may either use a 'reg' property to
|
||||
specify a specific range of reserved memory, or a 'size' property with
|
||||
optional constraints to request a dynamically allocated block of
|
||||
memory.
|
||||
|
||||
Following the generic-names recommended practice, node names should
|

reflect the purpose of the node (ie. "framebuffer" or "dma-pool").
|
||||
Unit address (@<address>) should be appended to the name if the node

is a static allocation.

A list of phandle and specifier pairs that describe static IO virtual

address space mappings and carveouts associated with a given reserved

memory region. The phandle in the first cell refers to the device for
|

which the mapping or carveout is to be created.
|
||||
|
||||
The specifier consists of an address/size pair and denotes the IO
|

virtual address range of the region for the given device. The exact

format depends on the values of the "#address-cells" and "#size-cells"

properties of the device referenced via the phandle.
|

|

When used in combination with a "reg" property, an IOVA mapping is to
|

be established for this memory region. One example where this can be
|

useful is to create an identity mapping for physical memory that the
|
||||
firmware has configured some hardware to access (such as a bootsplash
|
||||
framebuffer).
|
||||
|
||||
If no "reg" property is specified, the "iommu-addresses" property
|
||||
defines carveout regions in the IOVA space for the given device. This
|
||||
can be useful if a certain memory region should not be mapped through

the IOMMU.

This indicates a region of memory meant to be used as a pool

region would be the only region accessible to those devices.
|
||||
When using this, the no-map and reusable properties must not

||||
be set, so the operating system can create a virtual mapping
|
||||
that will be used for synchronization. The main purpose for
|
||||
restricted DMA is to mitigate the lack of DMA access control
|
||||
on systems without an IOMMU, which could result in the DMA
|
||||
accessing the system memory at unexpected times and/or
|
||||
unexpected addresses, possibly leading to data leakage or
|
||||
corruption. The feature on its own provides a basic level of
|
||||
protection against the DMA overwriting buffer contents at
|
||||
unexpected times. However, to protect against general data
|
||||
leakage and system memory corruption, the system needs to
|
||||
provide way to lock down the memory access, e.g., MPU. Note
|
||||
that since coherent allocation needs remapping, one must set
|
||||
up another device coherent pool by shared-dma-pool and use
|
||||
dma_alloc_from_dev_coherent instead for atomic coherent
|
||||
allocation.

- dlg,wdt-sd: Set what happens on watchdog timeout. If this bit is set the

default chip's OTP setting for WATCHDOG_SD bit. If this property is NOT
