| | | | | | | | | | | | | | | | When driver is in IAP mode ic_type query may return 0xff. However iap_version will always be valid, so let's use it to determine parameters of the firmware that the controller is supposed to accept.

| | | | | | | | | | | | | | | | | | | | | | | | | | There are trackpoint devices that fail to respond to the PS2 command PSMOUSE_CMD_GETID if immediately queried after the parent device is deactivated. Add a small delay for the hardware to get in a sane state before sending any PS2 commands.

| * Input: sentelic - silence some underflow warningsDan Carpenter2015-08-211-6/+8
| | | | | | | | | | | | | | | | | | | | | | I have a static checker that complains when we check for an upper bound but don't have a corresponding check for a lower bound. With this code, the upper bound check seems not really required, so it is not a bug to leave the lower bound check out as well. But let's silence the warning by making these variables unsigned.

| | | | | | | | | | | | | | | | | | It takes a bit of time to go through controller power up sequence and initialization. To not stall the overall boot progress let's probe the controller asynchronously, given that userspace is usually prepared for hot-plugging of input devices and thus does not rely on particular ordering.

| | | | | | | | | | | | | | | | | | | | | | | | The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled.

The extended W-Mode confuses our driver and causes missing button presses on some Thinkpads (x250, T450s), so let's make sure we do not enable it. Also, according to the spec W mode "... bit is defined only in Absolute mode on pads whose capExtended capability bit is set. In Relative mode and in TouchPads without this capability, the bit is reserved and should be left at 0.", so let's make sure we respect this requirement as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the generic process_bitmap function has been improved to offer accurate coordinates for the first touch we can use it for v5 (dolphin) touchpads too. Besides being a nice code cleanup this also fixes the saw tooth pattern in the coordinates for the second touch the dolphin specific version had.

So far for v3, rushmore and v4 touchpads we've been reporting the coordinates of 2 opposite corners of the box when 2 fingers are touching. Ignoring the much better resolution data given in the normal position packet. This commit actually uses this data for the first touch, figures out which corner of the bounding box is closest to the first touch, and reports the coordinates of the opposite corner for the second touch, resulting in much better data for the first touch and for the single touch pointer-emulation events. This approach is similar to the one in alps_process_bitmap_dolphin, that function takes the single accurate touch info, calculates the distance to the center of the bounding box, and then puts the 2nd touch mirrored to the center. The downside of that approach is that if both touches move slowly in the same direction, the bounding box will stay the same for a while (as it is low res) and the second touch will thus been seen moving in the opposite direction until the bounding box actually changes, and then the second touch snaps to its new position resulting in a saw tooth pattern in the coordinates for the second touch, hence this new approach. This commit fixes 2 finger scrolling being choppy / jumpy on these touchpads. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | We should decode the position packet before the packet with the bitmap data.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pinnacle / Rushmore packets contain either position info, or bitmap info, never both. So far we've in essence been storing garbage in the position / bitmap fields of the fields struct when decoding a bitmap / pos packet. We've been relying on the following sequence to get away with this: 1) Decode bitmap packet 2) Process bitmap packet 3) Decode position packet 4) Use position / button info This patch allows us to change this sequence, which will allow using the position info when processing the bitmap for more accurate results.
