This commit adds a new trigger that can turn on LED when USB device gets
connected to the USB port. This can be useful for various home routers
that have USB port and a proper LED telling user a device is connected.
Right now this trigger is usable with a proper DT only, there isn't a
way to

I'm not sure how this makes sense. The limits are enforced and
collected per user or along the process hierarchy which can

The rst2pdf tool is a very broken toolchain, with is not capable
of parsing complex documents. As such, it doesn't build the
media book, failing with:
[ERROR] pdfbuilder.py:130 too many values to unpack
(using rst2pdf version 0.93.dev-r0 and Sphinx version 1.4.5)
So, make it build only

There are many basic ways to control processes, including capabilities,
cgroups and resource limits. However, there are far fewer ways to find out
useful values for the limits, except blind trial and error.

We can simplify handling of platform_get_irq into one place as it is
acceptable to see UIO_IRQ_NONE instead of a valid IRQ number. Some
devices don't have or don't need any interrupt to be handled. The
same change has been already done for
This patch extends uio_dmem_genirq driver to use recently
added memtypes as follows:
1. Use UIO_MEM_DEVICE memtype for MEM resources
2. Use UIO_MEM_PHYS_CACHE memtype for dynamic regions
when UIO DT node is marked as DMA coherent.

The variable i contains a total number of resources (including
IORESOURCE_IRQ). However, we want the dmem_region_start to point
after the last resource of type IORESOURCE_MEM. The original behaviour
leads (very likely) to skipping several UIO mapping

The uio_dmem_genirq works in a similar ways as uio_pdrv_genirq now.
It accepts the of_id module parameter to specify UIO compatible
string as module parameter. There are few other module parameters
to specify DT property name for number bits in DMA
On ARM64, the MMU supports special memory attributes for device
memory/registers. Due to this we have pgprot_device() provided
by asm/pgtable.h of arch/arm64.
On architectures that do not have special MMU attribute for device
memory/registers, the asm-generic/pgtable.h maps pgprot_device()
to
The goal of this patchset is to improve UIO framework and UIO dmem
driver to allow cache-coherent DMA accesses from user-space.
This patchset is based on two previous patchsets:
1) [PATCH v5 0/6] UIO driver for APM X-Gene QMTM
(Refer, http://www.spinics.net/lists/devicetree/msg58244.html)
2)
While trying to make gpu docs warning free I stumbled over one output
which wasn't following proper compiler error output standards. Fix it
up for more quickfix awesomeness.
