+What:		/sys/bus/amba/devices/.../driver_override
+Date:		September 2014
+Contact:	Antonios Motakis <a.motakis@virtualopensystems.com>
+Description:
+		This file allows the driver for a device to be specified which
+		will override standard OF, ACPI, ID table, and name matching.
+		When specified, only a driver with a name matching the value
+		written to driver_override will have an opportunity to bind to
+		the device. The override is specified by writing a string to the
+		driver_override file (echo vfio-amba > driver_override)	and may
+		be cleared with an empty string (echo > driver_override).
+		This returns the device to standard matching rules binding.
+		Writing to driver_override does not automatically unbind the
+		device from its current driver or make any attempt to
+		automatically load the specified driver. If no driver with a
+		matching name is currently loaded in the kernel, the device will
+		not bind to any driver. This also allows devices to opt-out of
+		driver binding using a driver_override name such as "none".
+		Only a single driver may be specified in the override, there is
+		no support for parsing delimiters.

+Introduction
+------------
+This document gives useful information about the ARM Atmel SoCs that are
+currently supported in Linux Mainline (you know, the one on kernel.org).
+
+It is important to note that the Atmel | SMART ARM-based MPU product line is
+historically named "AT91" or "at91" throughout the Linux kernel development
+process even if this product prefix has completely disappeared from the
+official Atmel product name. Anyway, files, directories, git trees,
+git branches/tags and email subject always contain this "at91" sub-string.

+
+
+Device Tree for AT91 SoCs and boards
+------------------------------------
+All AT91 SoCs are converted to Device Tree. Since Linux 3.19, these products
+must use this method to boot the Linux kernel.
+
+Work In Progress statement:
+Device Tree files and Device Tree bindings that apply to AT91 SoCs and boards are
+considered as "Unstable". To be completely clear, any at91 binding can change at
+any time. So, be sure to use a Device Tree Binary and a Kernel Image generated from
+the same source tree.
+Please refer to the Documentation/devicetree/bindings/ABI.txt file for a
+definition of a "Stable" binding/ABI.
+This statement will be removed by AT91 MAINTAINERS when appropriate.
+
+Naming conventions and best practice:
+- SoCs Device Tree Source Include files are named after the official name of
+  the product (at91sam9g20.dtsi or sama5d33.dtsi for instance).
+- Device Tree Source Include files (.dtsi) are used to collect common nodes that can be
+  shared across SoCs or boards (sama5d3.dtsi or at91sam9x5cm.dtsi for instance).
+  When collecting nodes for a particular peripheral or topic, the identifier have to
+  be placed at the end of the file name, separated with a "_" (at91sam9x5_can.dtsi
+  or sama5d3_gmac.dtsi for example).
+- board Device Tree Source files (.dts) are prefixed by the string "at91-" so
+  that they can be identified easily. Note that some files are historical exceptions
+  to this rule (sama5d3[13456]ek.dts, usb_a9g20.dts or animeo_ip.dts for example).

-			S3C2410 DMA
-			===========
-
-Introduction
-------------
-
-   The kernel provides an interface to manage DMA transfers
-   using the DMA channels in the CPU, so that the central
-   duty of managing channel mappings, and programming the
-   channel generators is in one place.
-
-
-DMA Channel Ordering
---------------------
-
-   Many of the range do not have connections for the DMA
-   channels to all sources, which means that some devices
-   have a restricted number of channels that can be used.
-
-   To allow flexibility for each CPU type and board, the
-   DMA code can be given a DMA ordering structure which
-   allows the order of channel search to be specified, as
-   well as allowing the prohibition of certain claims.
-
-   struct s3c24xx_dma_order has a list of channels, and
-   each channel within has a slot for a list of DMA
-   channel numbers. The slots are searched in order for
-   the presence of a DMA channel number with DMA_CH_VALID
-   or-ed in.
-
-   If the order has the flag DMA_CH_NEVER set, then after
-   checking the channel list, the system will return no
-   found channel, thus denying the request.
-
-   A board support file can call s3c24xx_dma_order_set()
-   to register a complete ordering set. The routine will
-   copy the data, so the original can be discarded with
-   __initdata.

+- The original lower boundary, the soft limit, is defined as a limit
+  that is per default unset.  As a result, the set of cgroups that
+  global reclaim prefers is opt-in, rather than opt-out.  The costs
+  for optimizing these mostly negative lookups are so high that the
+  implementation, despite its enormous size, does not even provide the
+  basic desirable behavior.  First off, the soft limit has no
+  hierarchical meaning.  All configured groups are organized in a
+  global rbtree and treated like equal peers, regardless where they
+  are located in the hierarchy.  This makes subtree delegation
+  impossible.  Second, the soft limit reclaim pass is so aggressive
+  that it not just introduces high allocation latencies into the
+  system, but also impacts system performance due to overreclaim, to
+  the point where the feature becomes self-defeating.
+
+  The memory.low boundary on the other hand is a top-down allocated
+  reserve.  A cgroup enjoys reclaim protection when it and all its
+  ancestors are below their low boundaries, which makes delegation of
+  subtrees possible.  Secondly, new cgroups have no reserve per
+  default and in the common case most cgroups are eligible for the
+  preferred reclaim pass.  This allows the new low boundary to be
+  efficiently implemented with just a minor addition to the generic
+  reclaim code, without the need for out-of-band data structures and
+  reclaim passes.  Because the generic reclaim code considers all
+  cgroups except for the ones running low in the preferred first
+  reclaim pass, overreclaim of individual groups is eliminated as
+  well, resulting in much better overall workload performance.
+
+- The original high boundary, the hard limit, is defined as a strict
+  limit that can not budge, even if the OOM killer has to be called.
+  But this generally goes against the goal of making the most out of
+  the available memory.  The memory consumption of workloads varies
+  during runtime, and that requires users to overcommit.  But doing
+  that with a strict upper limit requires either a fairly accurate
+  prediction of the working set size or adding slack to the limit.
+  Since working set size estimation is hard and error prone, and
+  getting it wrong results in OOM kills, most users tend to err on the
+  side of a looser limit and end up wasting precious resources.
+
+  The memory.high boundary on the other hand can be set much more
+  conservatively.  When hit, it throttles allocations by forcing them
+  into direct reclaim to work off the excess, but it never invokes the
+  OOM killer.  As a result, a high boundary that is chosen too
+  aggressively will not terminate the processes, but instead it will
+  lead to gradual performance degradation.  The user can monitor this
+  and make corrections until the minimal memory footprint that still
+  gives acceptable performance is found.
+
+  In extreme cases, with many concurrent allocations and a complete
+  breakdown of reclaim progress within the group, the high boundary
+  can be exceeded.  But even then it's mostly better to satisfy the
+  allocation from the slack available in other groups or the rest of
+  the system than killing the group.  Otherwise, memory.max is there
+  to limit this type of spillover and ultimately contain buggy or even
+  malicious applications.
+
+- The original control file names are unwieldy and inconsistent in
+  many different ways.  For example, the upper boundary hit count is
+  exported in the memory.failcnt file, but an OOM event count has to
+  be manually counted by listening to memory.oom_control events, and
+  lower boundary / soft limit events have to be counted by first
+  setting a threshold for that value and then counting those events.
+  Also, usage and limit files encode their units in the filename.
+  That makes the filenames very long, even though this is not
+  information that a user needs to be reminded of every time they type
+  out those names.
+
+  To address these naming issues, as well as to signal clearly that
+  the new interface carries a new configuration model, the naming
+  conventions in it necessarily differ from the old interface.
+
+- The original limit files indicate the state of an unset limit with a
