+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
+

+	the reverse engineering.

+ * This supports simple USB network links that don't require any special
+ * framing or hardware control operations.  The protocol used here is a
+ * strict subset of CDC Ethernet, with three basic differences reflecting
+ * the goal that almost any hardware should run it:
+ *
+ *  - Minimal runtime control:  one interface, no altsettings, and
+ *    no vendor or class specific control requests.  If a device is
+ *    configured, it is allowed to exchange packets with the host.
+ *    Fancier models would mean not working on some hardware.
+ *
+ *  - Minimal manufacturing control:  no IEEE "Organizationally
+ *    Unique ID" required, or an EEPROMs to store one.  Each host uses
+ *    one random "locally assigned" Ethernet address instead, which can
+ *    of course be overridden using standard tools like "ifconfig".
+ *    (With 2^46 such addresses, same-net collisions are quite rare.)
+ *
+ *  - There is no additional framing data for USB.  Packets are written
+ *    exactly as in CDC Ethernet, starting with an Ethernet header and
+ *    terminated by a short packet.  However, the host will never send a
+ *    zero length packet; some systems can't handle those robustly.
+ *
+ * Anything that can transmit and receive USB bulk packets can implement
+ * this protocol.  That includes both smart peripherals and quite a lot
+ * of "host-to-host" USB cables (which embed two devices back-to-back).
+ *
+ * Note that although Linux may use many of those host-to-host links
+ * with this "cdc_subset" framing, that doesn't mean there may not be a
+ * better approach.  Handling the "other end unplugs/replugs" scenario
+ * well tends to require chip-specific vendor requests.  Also, Windows
+ * peers at the other end of host-to-host cables may expect their own
+ * framing to be used rather than this "cdc_subset" model.

 /*
  * This is a generic "USB networking" framework that works with several
- * kinds of full and high speed networking devices:
- *
- *   + USB host-to-host "network cables", used for IP-over-USB links.
- *     These are often used for Laplink style connectivity products.
- *	- AnchorChip 2720
- *	- Belkin, eTEK (interops with Win32 drivers)
- *	- GeneSys GL620USB-A
- *	- NetChip 1080 (interoperates with NetChip Win32 drivers)
- *	- Prolific PL-2301/2302 (replaces "plusb" driver)
- *	- KC Technology KC2190
- *
- *   + Smart USB devices can support such links directly, using Internet
- *     standard protocols instead of proprietary host-to-device links.
- *	- Linux PDAs like iPaq, Yopy, and Zaurus
- *	- The BLOB boot loader (for diskless booting)
- *	- Linux "gadgets", perhaps using PXA-2xx or Net2280 controllers
- *	- Devices using EPSON's sample USB firmware
- *	- CDC-Ethernet class devices, such as many cable modems
- *
- *   + Adapters to networks such as Ethernet.
- *	- AX8817X based USB 2.0 products
- *
- * Links to these devices can be bridged using Linux Ethernet bridging.
- * With minor exceptions, these all use similar USB framing for network
- * traffic, but need different protocols for control traffic.
- *
- * USB devices can implement their side of this protocol at the cost
- * of two bulk endpoints; it's not restricted to "cable" applications.
- * See the SA1110, Zaurus, or EPSON device/client support in this driver;
- * slave/target drivers such as "usb-eth" (on most SA-1100 PDAs) or
- * "g_ether" (in the Linux "gadget" framework) implement that behavior
- * within devices.
- *
- *
- * CHANGELOG:
- *
- * 13-sep-2000	experimental, new
- * 10-oct-2000	usb_device_id table created. 
- * 28-oct-2000	misc fixes; mostly, discard more TTL-mangled rx packets.
- * 01-nov-2000	usb_device_id table and probing api update by
- *		Adam J. Richter <adam@yggdrasil.com>.
- * 18-dec-2000	(db) tx watchdog, "net1080" renaming to "usbnet", device_info
- *		and prolific support, isolate net1080-specific bits, cleanup.
- *		fix unlink_urbs oops in D3 PM resume code path.
- *
- * 02-feb-2001	(db) fix tx skb sharing, packet length, match_flags, ...
- * 08-feb-2001	stubbed in "linuxdev", maybe the SA-1100 folk can use it;
- *		AnchorChips 2720 support (from spec) for testing;
- *		fix bit-ordering problem with ethernet multicast addr
- * 19-feb-2001  Support for clearing halt conditions. SA1100 UDC support
- *		updates. Oleg Drokin (green@iXcelerator.com)
- * 25-mar-2001	More SA-1100 updates, including workaround for ip problem
- *		expecting cleared skb->cb and framing change to match latest
- *		handhelds.org version (Oleg).  Enable device IDs from the
- *		Win32 Belkin driver; other cleanups (db).
- * 16-jul-2001	Bugfixes for uhci oops-on-unplug, Belkin support, various
- *		cleanups for problems not yet seen in the field. (db)
- * 17-oct-2001	Handle "Advance USBNET" product, like Belkin/eTEK devices,
- *		from Ioannis Mavroukakis <i.mavroukakis@btinternet.com>;
- *		rx unlinks somehow weren't async; minor cleanup.
- * 03-nov-2001	Merged GeneSys driver; original code from Jiun-Jie Huang
- *		<huangjj@genesyslogic.com.tw>, updated by Stanislav Brabec
- *		<utx@penguin.cz>.  Made framing options (NetChip/GeneSys)
- *		tie mostly to (sub)driver info.  Workaround some PL-2302
- *		chips that seem to reject SET_INTERFACE requests.
- *
- * 06-apr-2002	Added ethtool support, based on a patch from Brad Hards.
- *		Level of diagnostics is more configurable; they use device
- *		location (usb_device->devpath) instead of address (2.5).
- *		For tx_fixup, memflags can't be NOIO.
- * 07-may-2002	Generalize/cleanup keventd support, handling rx stalls (mostly
- *		for USB 2.0 TTs) and memory shortages (potential) too. (db)
- *		Use "locally assigned" IEEE802 address space. (Brad Hards)
- * 18-oct-2002	Support for Zaurus (Pavel Machek), related cleanup (db).
- * 14-dec-2002	Remove Zaurus-private crc32 code (Pavel); 2.5 oops fix,
- * 		cleanups and stubbed PXA-250 support (db), fix for framing
- * 		issues on Z, net1080, and gl620a (Toby Milne)
- *
- * 31-mar-2003	Use endpoint descriptors:  high speed support, simpler sa1100
- * 		vs pxa25x, and CDC Ethernet.  Throttle down log floods on
- * 		disconnect; other cleanups. (db)  Flush net1080 fifos
- * 		after several sequential framing errors. (Johannes Erdfelt)
- * 22-aug-2003	AX8817X support (Dave Hollis).
- * 14-jun-2004  Trivial patch for AX8817X based Buffalo LUA-U2-KTX in Japan
- *		(Neil Bortnak)
- * 03-nov-2004	Trivial patch for KC2190 (KC-190) chip. (Jonathan McDowell)
- *
- * 01-feb-2005	AX88772 support (Phil Chang & Dave Hollis)
