Input: iforce - fix control-message timeout

2021-11-10T07:12:17Z

USB control-message timeouts are specified in milliseconds and should specifically not vary with CONFIG_HZ.

Input: ili210x - reduce sample period to 15ms

2021-11-10T06:23:02Z

Modern devices may redraw display at 60 Hz, make sure we have one input sample per one frame. Reduce sample period to 15ms, so we would get up to 66.6 samples per second, although realistically with all the jitter and extra scheduling wiggle room, we would end up just above 60 samples per second. This should be a good compromise between sampling too often and sampling too seldom.

Input: ili210x - improve polled sample spacing

2021-11-10T06:23:00Z

Currently the ili210x driver implements a threaded interrupt handler which starts upon edge on the interrupt line, and then polls the touch controller for samples. Every time a sample is obtained from the controller, the thread function checks whether further polling is required, and if so, waits fixed amount of time before polling for next sample. The delay between consecutive samples can thus vary greatly, because the I2C transfer required to retrieve the sample from the controller takes different amount of time on different platforms. Furthermore, different models of the touch controllers supported by this driver require different delays during retrieval of samples too. Instead of waiting fixed amount of time before polling for next sample, determine how much time passed since the beginning of sampling cycle and then wait only the remaining amount of time within the sampling cycle. This makes the driver deliver samples with equal spacing between them. Signed-off-by: Marek Vasut Link: https://lore.kernel.org/r/20211108005216.480525-1-marex@denx.de Signed-off-by: Dmitry Torokhov

Input: ili210x - special case ili251x sample read out

2021-11-10T06:22:59Z

The ili251x touch controller needs 5ms delay between sending I2C device address and register address, and, writing or reading register data. According to downstream ili251x example code, this 5ms delay is not required when reading touch samples out of the controller. Implement such a special case.

Input: elantench - fix misreporting trackpoint coordinates

2021-11-10T06:22:43Z

Some firmwares occasionally report bogus data from trackpoint, with X or Y displacement being too large (outside of [-127, 127] range). Let's drop such packets so that we do not generate jumps.

Input: synaptics-rmi4 - Fix device hierarchy

2021-11-06T02:46:21Z

The created rmi device is orphan, which breaks the real device hierarchy, and can cause some trouble, especially during suspend and resume sequences. E.g. in case of I2C, rmi dev should be child of the I2C client device. Fix this, assigning the transport device as parent of the rmi device.

Input: i8042 - Add quirk for Fujitsu Lifebook T725

2021-11-05T23:33:00Z

Fujitsu Lifebook T725 laptop requires, like a few other similar models, the nomux and notimeout options to probe the touchpad properly. This patch adds the corresponding quirk entries.
