Fix sparse warning: drivers/input/touchscreen/goodix.c:182:26: warning: Variable length array is used. Replace the variable length array with fixed length. Some Goodix devices have maximum 5 touch points, while others have 10 touch points. Using the maximum length (80 bytes) for all devices will lead to wasting 40 bytes on stack when using devices with maximum 5 touch points. However, that is preferable to using kmalloc which will use even more resources. Signed-off-by:

Previously the elan_i2c touchpad driver would simply request the firmware "/lib/firmware/elan_i2c.bin", which does not work well if there are multiple such devices in the system. Let's append the "product ID" (by using the same function as the sysfs interface for consistency) to the filename. This results in filenames of the form "/lib/firmware/elan_i2c_72.0.bin", allowing you to support multiple elan_i2c touchpads on the same device by simply naming each device's FW with its corresponding product ID. This way when you trigger a fw update the driver will load the correct binary. Signed-off-by:

Focaltech touchpads report finger width in packet[5] of absolute packet. Range for width in raw format is 0x10 - 0x70. Second half-byte is always 0. 0xff is reported, when a large contact area is detected. This can be handled in userspace. Signed-off-by:

The platform_sysrq_reset_seq code was intended as a way for an embedded platform to provide its own sysrq sequence at compile time. After over two years, nobody has started using it in an upstream kernel, and the platforms that were interested in it have moved on to devicetree, which can be used to configure the sequence without requiring kernel changes. The method is also incompatible with the way that most architectures build support for multiple platforms into a single kernel. Now the code is producing warnings when built with gcc-5.1: drivers/tty/sysrq.c: In function 'sysrq_init': drivers/tty/sysrq.c:959:33: warning: array subscript is above array bounds [-Warray-bounds] key = platform_sysrq_reset_seq[i]; We could fix this, but it seems unlikely that it will ever be used, so let's just remove the code instead. We still have the option to pass the sequence either in DT, using the kernel command line, or using the /sys/module/sysrq/parameters/reset_seq file. Fixes: 154b7a48 ("Input: sysrq - allow specifying alternate reset sequence") Signed-off-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:

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.

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:
