+Programming Sequence for Register Reading/Writing
+=================================================
+
+Register inversion requirement:
+
+Following values needed to be inverted(the '~' operator in C) before being
+sent to FSP::
+
+ 0xe8, 0xe9, 0xee, 0xf2, 0xf3 and 0xff.
+
+Register swapping requirement:
+
+Following values needed to have their higher 4 bits and lower 4 bits being
+swapped before being sent to FSP::
+
+ 10, 20, 40, 60, 80, 100 and 200.
+
+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. if the register address being to read is not required to be
+ inverted(refer to the 'Register inversion requirement' section),
+ goto step 6
+
+ a. send 0x68 PS/2 command to FSP;
+
+ b. send the inverted register address to FSP and goto step 8;
+
+ 6. if the register address being to read is not required to be
+ swapped(refer to the 'Register swapping requirement' section),
+ goto step 7
+
+ a. send 0xcc PS/2 command to FSP;
+
+ b. send the swapped register address to FSP and goto step 8;
+
+ 7. send 0x66 PS/2 command to FSP;
+
+ a. send the original register address to FSP and goto step 8;
+
+ 8. send 0xe9(status request) PS/2 command to FSP;
+
+ 9. the 4th byte of the response read from FSP should be the
+ requested register value(?? indicates don't care byte)::
+
+ host: 0xe9
+ 3888: 0xfa (??) (??) (val)
+
+ * Note that since the Cx release, the hardware will return 1's
+ complement of the register value at the 3rd byte of status request
+ result::
+
+ host: 0xe9
+ 3888: 0xfa (??) (~val) (val)
+
+Register writing sequence:
+
+ 1. send 0xf3 PS/2 command to FSP;
+
+ 2. if the register address being to write is not required to be
+ inverted(refer to the 'Register inversion requirement' section),
+ goto step 3
+

+
+ b. send the inverted register address to FSP and goto step 5;
+
+ 3. if the register address being to write is not required to be
+ swapped(refer to the 'Register swapping requirement' section),

+
+ 9. the register writing sequence is completed.
+
+ * Since the Cx release, the hardware will return 1's
+ complement of the register value at the 3rd byte of status request

+ command to FSP at the end of register writing to verify that the
+ register writing operation is successful (?? indicates don't care
+ byte)::
+
+ host: 0xe9
+ 3888: 0xfa (??) (~val) (val)
+
+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
+
+ a. send 0x47 PS/2 command to FSP;
+
+ b. 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
+
+ a. send 0x44 PS/2 command to FSP;
+
+ b. 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::
