+What: /sys/dev
+Date: April 2008
+KernelVersion: 2.6.26
+Contact: Dan Williams <dan.j.williams@intel.com>
+Description: The /sys/dev tree provides a method to look up the sysfs
+ path for a device using the information returned from
+ stat(2). There are two directories, 'block' and 'char',
+ beneath /sys/dev containing symbolic links with names of
+ the form "<major>:<minor>". These links point to the
+ corresponding sysfs path for the given device.
+
+ Example:
+ $ readlink /sys/dev/block/8:32
+ ../../block/sdc
+
+ Entries in /sys/dev/char and /sys/dev/block will be
+ dynamically created and destroyed as devices enter and
+ leave the system.

could race with data DMA. Mapping the memory used for completion
indications with DMA_ATTR_WRITE_BARRIER would prevent the race.
+DMA_ATTR_WEAK_ORDERING
+----------------------
+
+DMA_ATTR_WEAK_ORDERING specifies that reads and writes to the mapping
+may be weakly ordered, that is that reads and writes may pass each other.
+
+Since it is optional for platforms to implement DMA_ATTR_WEAK_ORDERING,
+those that do not will simply ignore the attribute and exhibit default
+behavior.

represents the total interrupt count. You can use this number
to figure out if you missed some interrupts.
</para>
+ <para>
+ For some hardware that has more than one interrupt source internally,
+ but not separate IRQ mask and status registers, there might be
+ situations where userspace cannot determine what the interrupt source
+ was if the kernel handler disables them by writing to the chip's IRQ
+ register. In such a case, the kernel has to disable the IRQ completely
+ to leave the chip's register untouched. Now the userspace part can
+ determine the cause of the interrupt, but it cannot re-enable
+ interrupts. Another cornercase is chips where re-enabling interrupts
+ is a read-modify-write operation to a combined IRQ status/acknowledge
+ register. This would be racy if a new interrupt occurred
+ simultaneously.
+ </para>
+ <para>
+ To address these problems, UIO also implements a write() function. It
+ is normally not used and can be ignored for hardware that has only a
+ single interrupt source or has separate IRQ mask and status registers.
+ If you need it, however, a write to <filename>/dev/uioX</filename>
+ will call the <function>irqcontrol()</function> function implemented
+ by the driver. You have to write a 32-bit value that is usually either
+ 0 or 1 to disable or enable interrupts. If a driver does not implement
+ <function>irqcontrol()</function>, <function>write()</function> will
+ return with <varname>-ENOSYS</varname>.
+ </para>
<para>
To handle interrupts properly, your custom kernel module can
<function>open()</function>, you will probably also want a custom
<function>release()</function> function.

+X - Specifying Device Power Management Information (sleep property)
+===================================================================
+
+Devices on SOCs often have mechanisms for placing devices into low-power
+states that are decoupled from the devices' own register blocks. Sometimes,
+this information is more complicated than a cell-index property can
+reasonably describe. Thus, each device controlled in such a manner
+may contain a "sleep" property which describes these connections.
+
+The sleep property consists of one or more sleep resources, each of
+which consists of a phandle to a sleep controller, followed by a
+controller-specific sleep specifier of zero or more cells.
+
+The semantics of what type of low power modes are possible are defined
+by the sleep controller. Some examples of the types of low power modes
+that may be supported are:
+
+ - Dynamic: The device may be disabled or enabled at any time.
+ - System Suspend: The device may request to be disabled or remain
+ awake during system suspend, but will not be disabled until then.
+ - Permanent: The device is disabled permanently (until the next hard
+ reset).
+
+Some devices may share a clock domain with each other, such that they should
+only be suspended when none of the devices are in use. Where reasonable,
+such nodes should be placed on a virtual bus, where the bus has the sleep
+property. If the clock domain is shared among devices that cannot be
+reasonably grouped in this manner, then create a virtual sleep controller
+(similar to an interrupt nexus, except that defining a standardized
+sleep-map should wait until its necessity is demonstrated).

+ that is set in the cell, the corresponding bit in SCCR will be saved
+ and cleared on suspend, and restored on resume. This sleep controller
+ supports disabling and resuming devices at any time.
+
+ fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of

hardware handshaking is off. It behaves as the RTS hardware
handshaking signal when hardware handshaking is selected.
software handshaking. So switching on the fly is not really an
option.
-I actually prefer to use the "Specialix DTR/RTS pin is RTS" option.
+I actually prefer to use the "specialix.sx_rtscts=1" option.
This makes the DTR/RTS pin always an RTS pin, and ioctls to
change DTR are always ignored. I have a cable that is configured
for this.
You have to WRITE to the address register to even
read-probe a CD186x register. Disable autodetection?
-- Specialix: any suggestions?
- - Arbitrary baud rates are not implemented yet.
- If you need this, bug me about it.

- say N here, the driver will use the pin as "DTR" when the tty is in
- software handshake mode. If you say Y here or hardware handshake is
- on, it will always be RTS. Read the file

+ The channel interface driver allows applications to communicate

+ servers. Upon loading, the driver creates /dev/hpilo/dXccbN files,
+ which can be used to gather data from the management processor,
+ via read and write system calls.
+
+ To compile this driver as a module, choose M here: the
+ module will be called hpilo.

Code in this driver inspired by and in a number of places taken
from Brian Warner's original Keyspan-PDA driver.
This driver has been put together with the support of Innosys, Inc.
and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
Thanks Guys :)

Thanks to Paulus for miscellaneous tidy ups, some largish chunks
of much nicer and/or completely new code and (perhaps most uniquely)
having the patience to sit down and explain why and where he'd changed
- stuff.

Merged Paul's changes with my USA-49W mods. Work in progress
still...
