-What:	PCI Name Database (CONFIG_PCI_NAMES)
-When:	July 2005
-Why:	It bloats the kernel unnecessarily, and is handled by userspace better
-	(pciutils supports it.)  Will eliminate the need to try to keep the
-	pci.ids file in sync with the sf.net database all of the time.

+Driver documentation for yealink usb-p1k phones
+
+0. Status
+~~~~~~~~~
+
+The p1k is a relatively cheap usb 1.1 phone with:
+  - keyboard		full support, yealink.ko / input event API
+  - LCD			full support, yealink.ko / sysfs API
+  - LED			full support, yealink.ko / sysfs API
+  - dialtone		full support, yealink.ko / sysfs API
+  - ringtone		full support, yealink.ko / sysfs API
+  - audio playback   	full support, snd_usb_audio.ko / alsa API
+  - audio record     	full support, snd_usb_audio.ko / alsa API
+
+For vendor documentation see http://www.yealink.com
+
+
+1. Compilation (stand alone version)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Currently only kernel 2.6.x.y versions are supported.
+In order to build the yealink.ko module do:
+
+  make
+
+If you encounter problems please check if in the MAKE_OPTS variable in
+the Makefile is pointing to the location where your kernel sources
+are located, default /usr/src/linux.
+
+
+
+2. keyboard features
+~~~~~~~~~~~~~~~~~~~~
+The current mapping in the kernel is provided by the map_p1k_to_key
+function:
+
+   Physical USB-P1K button layout	input events
+
+
+              up			     up
+        IN           OUT		left,	right
+             down			    down
+
+      pickup   C    hangup		enter, backspace, escape
+        1      2      3			1, 2, 3
+        4      5      6			4, 5, 6,
+        7      8      9			7, 8, 9,
+        *      0      #			*, 0, #,
+
+  The "up" and "down" keys, are symbolised by arrows on the button.
+  The "pickup" and "hangup" keys are symbolised by a green and red phone
+  on the button.
+
+
+3. LCD features
+~~~~~~~~~~~~~~~
+The LCD is divided and organised as a 3 line display:
+
+    |[]   [][]   [][]   [][]   in   |[][]
+    |[] M [][] D [][] : [][]   out  |[][]
+                              store
+
+    NEW REP         SU MO TU WE TH FR SA
+
+    [] [] [] [] [] [] [] [] [] [] [] []
+    [] [] [] [] [] [] [] [] [] [] [] []
+
+
+Line 1	Format (see below)	: 18.e8.M8.88...188
+	Icon names		:   M  D  :  IN OUT STORE
+Line 2  Format			: .........
+	Icon name		: NEW REP SU MO TU WE TH FR SA
+Line 3  Format			: 888888888888
+
+
+Format description:
+  From a user space perspective the world is seperated in "digits" and "icons".
+  A digit can have a character set, an icon can only be ON or OFF.
+
+  Format specifier
+    '8' :  Generic 7 segment digit with individual addressable segments
+
+    Reduced capabillity 7 segm digit, when segments are hard wired together.
+    '1' : 2 segments digit only able to produce a 1.
+    'e' : Most significant day of the month digit,
+          able to produce at least 1 2 3.
+    'M' : Most significant minute digit,
+          able to produce at least 0 1 2 3 4 5.
+
+    Icons or pictograms:
+    '.' : For example like AM, PM, SU, a 'dot' .. or other single segment
+	  elements.
+
+
+4. Driver usage
+~~~~~~~~~~~~~~~
+For userland the following interfaces are available using the sysfs interface:
+  /sys/.../
+           line1	Read/Write, lcd line1
+           line2	Read/Write, lcd line2
+           line3	Read/Write, lcd line3
+
+	   get_icons    Read, returns a set of available icons.
+	   hide_icon    Write, hide the element by writing the icon name.
+	   show_icon    Write, display the element by writing the icon name.
+
+	   map_seg7	Read/Write, the 7 segments char set, common for all
+	   		yealink phones. (see map_to_7segment.h)
+
+	   ringtone	Write, upload binary representation of a ringtone,
+	   		see yealink.c. status EXPERIMENTAL due to potential
+			races between async. and sync usb calls.
+
+
+4.1 lineX
+~~~~~~~~~
+Reading /sys/../lineX will return the format string with its current value:
+
+  Example:
+  cat ./line3
+  888888888888
+  Linux Rocks!
+
+Writing to /sys/../lineX will set the coresponding LCD line.
+ - Excess characters are ignored.
+ - If less characters are written than allowed, the remaining digits are
+   unchanged.
+ - The tab '\t'and '\n' char does not overwrite the original content.
+ - Writing a space to an icon will always hide its content.
+
+  Example:
+  date +"%m.%e.%k:%M"  | sed 's/^0/ /' > ./line1
+
+  Will update the LCD with the current date & time.
+
+
+4.2 get_icons
+~~~~~~~~~~~~~
+Reading will return all available icon names and its current settings:
+
+  cat ./get_icons
+  on M
+  on D
+  on :
+     IN
+     OUT
+     STORE
+     NEW
+     REP
+     SU
+     MO
+     TU
+     WE
+     TH
+     FR
+     SA
+     LED
+     DIALTONE
+     RINGTONE
+
+
+4.3 show/hide icons
+~~~~~~~~~~~~~~~~~~~
+Writing to these files will update the state of the icon.
+Only one icon at a time can be updated.
+
+If an icon is also on a ./lineX the corresponding value is
+updated with the first letter of the icon.
+
+  Example - light up the store icon:
+  echo -n "STORE" > ./show_icon
+
+  cat ./line1
+  18.e8.M8.88...188
+               S
+
+  Example - sound the ringtone for 10 seconds:
+  echo -n RINGTONE > /sys/..../show_icon
+  sleep 10
+  echo -n RINGTONE > /sys/..../hide_icon
+
+
+5. Sound features
+~~~~~~~~~~~~~~~~~
+Sound is supported by the ALSA driver: snd_usb_audio
+
+One 16-bit channel with sample and playback rates of 8000 Hz is the practical
+limit of the device.
+
+  Example - recording test:
+  arecord -v -d 10 -r 8000 -f S16_LE -t wav  foobar.wav
+
+  Example - playback test:
+  aplay foobar.wav
+
+
+6. Credits & Acknowledgments
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  - Olivier Vandorpe, for starting the usbb2k-api project doing much of
+	the reverse engineering.
+  - Martin Diehl, for pointing out how to handle USB memory allocation.
+  - Dmitry Torokhov, for the numerous code reviews and suggestions.

-	/* These are here in an effort to more fully work around

-	 * occurs soon after a mispredicted branch, the chip can stop
-	 * executing instructions until a trap occurs.  Therefore, if
-	 * interrupts are disabled, the chip can hang forever.
-	 *
-	 * It used to be believed that the memory barrier had to be
-	 * right in the delay slot, but a case has been traced
-	 * recently wherein the memory barrier was one instruction
-	 * after the branch delay slot and the chip still hung.  The
-	 * offending sequence was the following in sym_wakeup_done()
-	 * of the sym53c8xx_2 driver:
-	 *
-	 *	call	sym_ccb_from_dsa, 0
-	 *	 movge	%icc, 0, %l0
-	 *	brz,pn	%o0, .LL1303
-	 *	 mov	%o0, %l2
-	 *	membar	#LoadLoad
-	 *
-	 * The branch has to be mispredicted for the bug to occur.
-	 * Therefore, we put the memory barrier explicitly into a
-	 * "branch always, predicted taken" delay slot to avoid the
-	 * problem case.
