The variable no_decel is bool type so assigning "true" instead of "1". Also, synaptics_i2c_get_input() has bool return type, so let's use "false" there. Signed-off-by:

The STMPE MFD is only used with device tree configured systems (and STMPE MFD core depends on OF), so force the configuration to come from device tree only. Tested-by:

When STMPE is instantiated via device tree individual MFD cells rae formed with OF modaliases, not platform modaliases, and so we need to add OF device table to the driver if we want it to load automatically: of:Nstmpe_touchscreenT<NULL>Cst,stmpe-ts Reported-by:

The I2C subsystem can match devices without explicit OF support based on the part of their compatible property after the comma. However, this mechanism uses the first compatible value only. For adxl34x OF device nodes the compatible property will contain the more specific "adi,adxl345" or "adi,adxl346" value first. This prevents the device node from being matched with the adxl34x driver. Fix this by adding an OF match table with an "adi,adxl345" compatible entry. There's no need to add the "adi,adxl346" entry as the ADXL346 is backward-compatible with the ADXL345 with differences handled by runtime detection of the device model. Signed-off-by:

DT nodes should use the more specific adi,adxl345 and adi,adxl346 compatible values instead. As the ADXL346 is backward-compatible with the ADXL345, ADXL346 nodes must list both adi,adxl346 and adi,adxl345, in that order. Signed-off-by:

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. Signed-off-by:

With the recent process_bitmap() changes all semi-mt devices always report the first finger down in slot 0, so stop using input-mt finger tracking for these. Signed-off-by:

Hans de Goede authored
All alps semi-mt touchpads give us the following data when 2 (or more) fingers are touching: 1 more or less accurate touch for the first finger down, and a bitmap with columns and rows in which 1 or more fingers are seen resulting in a crude (low res) bounding box. 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:

We should decode the position packet before the packet with the bitmap data. This way we can use the more accurate position info in process_bitmap() to get better results. Signed-off-by:
-
Hans de Goede authored
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.

Change alps_decode_rushmore to do all decoding itself, rather then relying on alps_decode_pinnacle and then overriding some fields + or-ing in some bits. This is a preparation patch for modifying the decode functions to properly differentiate between position and bitmap packets. Signed-off-by:

In datasheet of max7359 there is the following description of this flag: 0 - INT cleared when FIFO empty, 1 - INT cleared after host read. In this mode, I2C should read FIFO until interrupt condition removed, or further INT may be lost. So, if we set this flag, we have to read FIFO until it becomes empty. But in interrupt we read FIFO just once. This lead to "keyboard" hang until reboot, if we press several keys, because of interrupt handler read just one "press" from FIFO and clear interrupt.

Wait a little bit longer, 50mS instead of 20mS, until the driver starts polling for pen-up. The problematic behavior before this patch is applied is as follows. The behavior was observed on the STMPE610QTR controller. Upon a physical pen-down event, the touchscreen reports one set of x-y-p coordinates and a pen-down event. After that, the pen-up polling is triggered and since the controller is not ready yet, the polling mistakenly detects a pen-up event while the physical state is still such that the pen is down on the touch surface. The pen-up handling flushes the controller FIFO, so after that, all the samples in the controller are discarded. The controller becomes ready shortly after this bogus pen-up handling and does generate again a pen-down interrupt. This time, the controller contains x-y-p samples which all read as zero. Since pressure value is zero, this set of samples is effectively ignored by userland. In the end, the driver just bounces between pen-down and bogus pen-up handling, generating no useful results. Fix this by giving the controller a bit more time before polling it for pen-up. Signed-off-by:

The MSB of the first byte read via I2C at the coordinates address indicates whether the data is valid or ready (called "buffer status" in the datasheets) when an interrupt is raised. Previously, this bit was ignored, which resulted in a lot of incorrect detections of "finger removed" events. Signed-off-by:

The event mask was specified as 0xF (4 bits) when in reality is 0x1F (5 bits) in order to be capable of representing all FIFO length values from 0 to 16. This caused a problem: when the keypad reported 16 pending events the driver took it as 0, and did nothing. This in turn caused the keypad to re-issue the interrupt over and over again.

The pull mask is created by looping each row (column) and building an 8-bit integer with the configuration. It is written byte-by-byte, when we reach the end of the rows (columns) or we're at the 3rd line (which finishes the first byte, since each pin is 2bits on the mask). However, this only works if we have at most 8 pins (2 bytes), which is not the case for the ADP5589. So, write the byte at each boundary (every 4 rows/columns). Signed-off-by:
