ALPS Touchpad Protocol
----------------------
Introduction
------------
Currently the ALPS touchpad driver supports four protocol versions in use by
ALPS touchpads, called versions 1, 2, 3, and 4. Information about the various
protocol versions is contained in the following sections.
Detection
---------
All ALPS touchpads should respond to the "E6 report" command sequence:
E8-E6-E6-E6-E9. An ALPS touchpad should respond with either 00-00-0A or
00-00-64.
If the E6 report is successful, the touchpad model is identified using the "E7
report" sequence: E8-E7-E7-E7-E9. The response is the model signature and is
matched against known models in the alps_model_data_array.
With protocol versions 3 and 4, the E7 report model signature is always
73-02-64. To differentiate between these versions, the response from the
"Enter Command Mode" sequence must be inspected as described below.
Command Mode
------------
Protocol versions 3 and 4 have a command mode that is used to read and write
one-byte device registers in a 16-bit address space. The command sequence
EC-EC-EC-E9 places the device in command mode, and the device will respond
with 88-07 followed by a third byte. This third byte can be used to determine
whether the devices uses the version 3 or 4 protocol.
To exit command mode, PSMOUSE_CMD_SETSTREAM (EA) is sent to the touchpad.
While in command mode, register addresses can be set by first sending a
specific command, either EC for v3 devices or F5 for v4 devices. Then the
address is sent one nibble at a time, where each nibble is encoded as a
command with optional data. This enoding differs slightly between the v3 and
v4 protocols.
Once an address has been set, the addressed register can be read by sending
PSMOUSE_CMD_GETINFO (E9). The first two bytes of the response contains the
address of the register being read, and the third contains the value of the
register. Registers are written by writing the value one nibble at a time
using the same encoding used for addresses.
Packet Format
-------------
In the following tables, the following notation is used.
CAPITALS = stick, miniscules = touchpad
?'s can have different meanings on different models, such as wheel rotation,
extra buttons, stick buttons on a dualpoint, etc.
PS/2 packet format
------------------
byte 0: 0 0 YSGN XSGN 1 M R L
byte 1: X7 X6 X5 X4 X3 X2 X1 X0
byte 2: Y7 Y6 Y5 Y4 Y3 Y2 Y1 Y0
Note that the device never signals overflow condition.
ALPS Absolute Mode - Protocol Verion 1
--------------------------------------
byte 0: 1 0 0 0 1 x9 x8 x7
byte 1: 0 x6 x5 x4 x3 x2 x1 x0
byte 2: 0 ? ? l r ? fin ges
byte 3: 0 ? ? ? ? y9 y8 y7
byte 4: 0 y6 y5 y4 y3 y2 y1 y0
byte 5: 0 z6 z5 z4 z3 z2 z1 z0
ALPS Absolute Mode - Protocol Version 2
---------------------------------------
byte 0: 1 ? ? ? 1 ? ? ?
byte 1: 0 x6 x5 x4 x3 x2 x1 x0
byte 2: 0 x10 x9 x8 x7 ? fin ges
byte 3: 0 y9 y8 y7 1 M R L
byte 4: 0 y6 y5 y4 y3 y2 y1 y0
byte 5: 0 z6 z5 z4 z3 z2 z1 z0

byte 1: 0 x6 x5 x4 x3 x2 x1 x0
byte 2: 0 x10 x9 x8 x7 0 fin ges

byte 6: 0 y9 y8 y7 1 m r l
byte 7: 0 y6 y5 y4 y3 y2 y1 y0
byte 8: 0 z6 z5 z4 z3 z2 z1 z0
ALPS Absolute Mode - Protocol Version 3
---------------------------------------
ALPS protocol version 3 has three different packet formats. The first two are
associated with touchpad events, and the third is associatd with trackstick
events.
The first type is the touchpad position packet.
byte 0: 1 ? x1 x0 1 1 1 1
byte 1: 0 x10 x9 x8 x7 x6 x5 x4
byte 2: 0 y10 y9 y8 y7 y6 y5 y4
byte 3: 0 M R L 1 m r l
byte 4: 0 mt x3 x2 y3 y2 y1 y0
byte 5: 0 z6 z5 z4 z3 z2 z1 z0
Note that for some devices the trackstick buttons are reported in this packet,
and on others it is reported in the trackstick packets.
The second packet type contains bitmaps representing the x and y axes. In the
bitmaps a given bit is set if there is a finger covering that position on the
given axis. Thus the bitmap packet can be used for low-resolution multi-touch
data, although finger tracking is not possible. This packet also encodes the
number of contacts (f1 and f0 in the table below).
byte 0: 1 1 x1 x0 1 1 1 1
byte 1: 0 x8 x7 x6 x5 x4 x3 x2
byte 2: 0 y7 y6 y5 y4 y3 y2 y1
byte 3: 0 y10 y9 y8 1 1 1 1
byte 4: 0 x14 x13 x12 x11 x10 x9 y0
byte 5: 0 1 ? ? ? ? f1 f0
This packet only appears after a position packet with the mt bit set, and
ususally only appears when there are two or more contacts (although
ocassionally it's seen with only a single contact).
The final v3 packet type is the trackstick packet.
byte 0: 1 1 x7 y7 1 1 1 1
byte 1: 0 x6 x5 x4 x3 x2 x1 x0
byte 2: 0 y6 y5 y4 y3 y2 y1 y0
byte 3: 0 1 0 0 1 0 0 0
byte 4: 0 z4 z3 z2 z1 z0 ? ?
byte 5: 0 0 1 1 1 1 1 1
ALPS Absolute Mode - Protocol Version 4
---------------------------------------
Protocol version 4 has an 8-byte packet format.
byte 0: 1 ? x1 x0 1 1 1 1
byte 1: 0 x10 x9 x8 x7 x6 x5 x4
byte 2: 0 y10 y9 y8 y7 y6 y5 y4
byte 3: 0 1 x3 x2 y3 y2 y1 y0
byte 4: 0 ? ? ? 1 ? r l
byte 5: 0 z6 z5 z4 z3 z2 z1 z0
byte 6: bitmap data (described below)
byte 7: bitmap data (described below)
The last two bytes represent a partial bitmap packet, with 3 full packets
required to construct a complete bitmap packet. Once assembled, the 6-byte
bitmap packet has the following format:
byte 0: 0 1 x7 x6 x5 x4 x3 x2
byte 1: 0 x1 x0 y4 y3 y2 y1 y0
byte 2: 0 0 ? x14 x13 x12 x11 x10
byte 3: 0 x9 x8 y9 y8 y7 y6 y5
byte 4: 0 0 0 0 0 0 0 0
byte 5: 0 0 0 0 0 0 0 y10
There are several things worth noting here.
1) In the bitmap data, bit 6 of byte 0 serves as a sync byte to
identify the first fragment of a bitmap packet.
2) The bitmaps represent the same data as in the v3 bitmap packets, although
the packet layout is different.
3) There doesn't seem to be a count of the contact points anywhere in the v4
protocol packets. Deriving a count of contact points must be done by
analyzing the bitmaps.
4) There is a 3 to 1 ratio of position packets to bitmap packets. Therefore
MT position can only be updated for every third ST position update, and
the count of contact points can only be updated every third packet as
well.
So far no v4 devices with tracksticks have been encountered.

Driver for tilt-switches connected via GPIOs
============================================
Generic driver to read data from tilt switches connected via gpios.
Orientation can be provided by one or more than one tilt switches,
i.e. each tilt switch providing one axis, and the number of axes
is also not limited.
Data structures:
----------------
The array of struct gpio in the gpios field is used to list the gpios
that represent the current tilt state.
The array of struct gpio_tilt_axis describes the axes that are reported
to the input system. The values set therein are used for the
input_set_abs_params calls needed to init the axes.
The array of struct gpio_tilt_state maps gpio states to the corresponding
values to report. The gpio state is represented as a bitfield where the
bit-index corresponds to the index of the gpio in the struct gpio array.
In the same manner the values stored in the axes array correspond to
the elements of the gpio_tilt_axis-array.
Example:
--------
Example configuration for a single TS1003 tilt switch that rotates around
one axis in 4 steps and emitts the current tilt via two GPIOs.

==============================================================================
* Programming Sequence for Page Register Reading/Writing
==============================================================================
In order to overcome the limitation of maximum number of registers
supported, the hardware separates register into different groups called
'pages.' Each page is able to include up to 255 registers.
The default page after power up is 0x82; therefore, if one has to get
access to register 0x8301, one has to use following sequence to switch
to page 0x83, then start reading/writing from/to offset 0x01 by using
the register read/write sequence described in previous section.
Page register reading sequence:
1. send 0xf3 PS/2 command to FSP;
2. send 0x66 PS/2 command to FSP;
3. send 0x88 PS/2 command to FSP;
4. send 0xf3 PS/2 command to FSP;
5. send 0x83 PS/2 command to FSP;
6. send 0x88 PS/2 command to FSP;
7. send 0xe9(status request) PS/2 command to FSP;
8. the response read from FSP should be the requested page value.
Page register writing sequence:
1. send 0xf3 PS/2 command to FSP;
2. send 0x38 PS/2 command to FSP;
3. send 0x88 PS/2 command to FSP;
4. send 0xf3 PS/2 command to FSP;
5. if the page address being written is not required to be
inverted(refer to the 'Register inversion requirement' section),
goto step 6
5a. send 0x47 PS/2 command to FSP;
5b. send the inverted page address to FSP and goto step 9;
6. if the page address being written is not required to be
swapped(refer to the 'Register swapping requirement' section),
goto step 7
6a. send 0x44 PS/2 command to FSP;
6b. send the swapped page address to FSP and goto step 9;
7. send 0x33 PS/2 command to FSP;
8. send the page address to FSP;
9. the page register writing sequence is completed.
==============================================================================
* Gesture ID
==============================================================================
Unlike other devices which sends multiple fingers' coordinates to host,
FSP processes multiple fingers' coordinates internally and convert them
into a 8 bits integer, namely 'Gesture ID.' Following is a list of
supported gesture IDs:
ID Description
0x86 2 finger straight up
0x82 2 finger straight down
0x80 2 finger straight right
0x84 2 finger straight left
0x8f 2 finger zoom in
0x8b 2 finger zoom out
0xc0 2 finger curve, counter clockwise
0xc4 2 finger curve, clockwise
0x2e 3 finger straight up
0x2a 3 finger straight down
0x28 3 finger straight right
0x2c 3 finger straight left
0x38 palm
==============================================================================
* Register Listing
==============================================================================
Registers are represented in 16 bits values. The higher 8 bits represent
the page address and the lower 8 bits represent the relative offset within
that particular page. Refer to the 'Programming Sequence for Page Register
Reading/Writing' section for instructions on how to change current page
address.
