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:

Since commit 1c6c6952 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. So pass the IRQF_ONESHOT flag in this case. The semantic patch that makes this change is available in scripts/coccinelle/misc/irqf_oneshot.cocci. 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:

According to Elan's firmware engineers we should not be subtracting 1 form the raw number of x and y traces so that the pitch size is correct. For example, if the touchpad x resolution is 2800 and x trace number is 20, the pitch size of x should be 2800/20 = 140, not 2800/19 = 147.36. Signed-off-by:

This change allows atmel_mxt_ts to bind to ACPI-enumerated devices in Google Pixel 2 (2015). While newer version of ACPI standard allow use of device-tree-like properties in device descriptions, the version of ACPI implemented in Google BIOS does not support them, and we have to resort to DMI data to specify exact characteristics of the devices (touchpad vs. touchscreen, GPIO to button mapping, etc). Pixel 1 continues to use i2c devices and platform data created by chromeos-laptop driver, since ACPI does not enumerate them. Reviewed-by:

VMMouse enables low-latency mouse-cursor-movements for VMWare and QEMU guests. By removing the guest cursor and using the host as a guest cursor the cursor movement appears instant although in reality there is some lag. To be able to do this, the host's view of the cursor position must exactly match the guest's view and an absolute pointer device is needed. Enter the VMMouse. While the VMMouse driver has historically been an Xorg user-space driver, implementing it as a kernel imput driver enables rootless Xorg and new compositing display servers for VMware guests.
