2017-01-18Input: tm2-touchkey - add touchkey driver support for TM2Jaechul Lee
This patch adds support for the TM2 touch key and led functionality. The driver interfaces with userspace through an input device and reports KEY_PHONE and KEY_BACK event types. LED brightness can be controlled by "/sys/class/leds/tm2-touchkey/brightness".

2017-01-17Input: tca8418 - use the interrupt trigger from the device treeMaxime Ripard
The TCA8418 might be used using different interrupt triggers on various boards. This is not working so far because the current code forces a falling edge trigger. The device tree already provides a trigger type, so let's use whatever it sets up, and since we can be loaded without DT, keep the old behaviour for the non-DT case.

2017-01-15Input: cyapa - use msleep() for long delayNicholas Mc Guire

2017-01-15Input: cyapa - use time based retry loopNicholas Mc Guire
Using counter based retry loops for peripherals results in the delay being significantly overrun during high-load situations where delay functions tend to be vary imprecise and overrun there timeouts. So condition the termination on the actual condition of 2s for the re-calibration to have been successful. As this is a very long delay there is no advantage in using high-resolution timers thus switching this to msleep().

2017-01-15Input: mpr121 - switch to device tree probeAkinobu Mita
This driver currently only supports legacy platform data probe.

2017-01-15Input: mpr121 - handle multiple bits change of status registerAkinobu Mita
This driver reports input events on their interrupts which are triggered by the sensor's status register changes. But only single bit change is reported in the interrupt handler. So if there are multiple bits are changed at almost the same time, other press or release events are ignored. This fixes it by detecting all changed bits in the status register.

The order of endpoints is well defined on official Xbox pads, but we have found at least one 3rd-party pad that doesn't follow the standard ("Titanfall 2 Xbox One controller" 0e6f:0165). Fortunately, we get lucky with this specific pad because it uses endpoint addresses that differ only by direction.

2016-12-18Input: i8042 - force synchronous probing of PNP driversDmitry Torokhov
We rely on the result of scanning PNP bus for keyboard and mouse devices to decide whether we should continue initialization of i8042 driver or not, so the probes can not be asynchronous. Also, it is not a good idea to unbind either of the PNP devices while i8042 is running, so let's disable bind/unbind for the PNP drivers through sysfs and rely on i8042 cleaning after itself properly. User can still unbind and rebind entire i8042 and that will take care of PNP drivers as well. Reviewed-by: Luis R.

We were assigning I2C bus controller instead of client as parent device. Besides being logically wrong, it messed up with devm handling of input device. As a result we were leaving input device and event node behind after rmmod-ing the driver, which lead to a kernel oops if one were to access the event node later. Let's remove the assignment and rely on devm_input_allocate_device() to set it up properly for us.

Semantics of NR_IRQS is different on machines with SPARSE_IRQ option disabled or enabled, in the latter case IRQs are allocated starting at least from the value specified by NR_IRQS and going upwards, so the check of (irq >= NR_IRQ) to decide about an error code returned by platform_get_irq() is completely invalid, don't attempt to overrule irq subsystem in the driver. The change fixes lpc32xx_keys driver initialization on boot: lpc32xx_keys 40050000.key: failed to get platform irq lpc32xx_keys: probe of 40050000.key failed with error -22 Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Acked-by: Sylvain Lemieux <slemieux.tyco@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

This is the way the other rmi function handlers will do this. This patch is needed on HID devices because the firmware reads F03 data registers and adds them to the HID attention report.

2016-11-30Input: imx6ul_tsc - convert int to u32Guy Shapiro
The code uses of_property_read_u32 and expects positive values. However, the values are stored in signed int variables. Additionally, the registers values are also stored in signed variables without a good reason (readl/writel expect u32). The only time this caused a real bug was in the new average-samples property, in which the property is numerically compared and implicitly expected to be positive. I believe it's better to change all the properties and registers to u32, for consistency and warnings reduction.
