2017-10-24Input: goodix - support gt1151 touchpanelMarcin Niestroj
Support was added based on Goodix GitHub repo [1]. There are two major differences between gt1151 and currently supported devices (gt9x): * CONFIG_DATA register has 0x8050 address instead of 0x8047, * config data checksum has 16-bit width instead of 8-bit. Also update goodix_i2c_test() function, so it reads ID register (which has the same address for all devices) instead of CONFIG_DATA (because its address is known only after reading ID of the device).

2017-10-19Input: gpio_mouse - kill off platform dataLinus Walleij
This is not used much: git grep gpio_mouse_platform_data shows that absolutely nothing in the kernel defines this platform data. It could be argued that the driver should be deleted. But that is a bit harsh I think since it seems generally useful. So this patch starts a series which repurposes it to be used with hardware nodes from device tree or ACPI. This first patch simply localize the platform data header and allocates a dummy platform data. Yes: this patch leaves the driver in a pretty useless state, but since nothing is instantiating this driver, it doesn't make it more useless than it already is. Later patches makes use of the driver.

2017-10-19Input: goodix - poll the 'buffer status' bit before reading dataPaul Cercueil
The Goodix panel triggers an interrupt on touch events. However, its registers will contain the valid values a short time after the interrupt, and not when it's raised. At that moment, the 'buffer status' bit is set. Previously, if the 'buffer status' bit was not set when the registers were read, the data was discarded and no input event was emitted, causing "finger down" or "finger up" events to be missed sometimes. This went unnoticed until v4.9, as the DesignWare I2C driver commonly used with this driver had enough latency for that bug to never trigger until commit 2702ea7dbec5 ("i2c: designware: wait for disable/enable only if necessary"). Now, in the IRQ handler we will poll (with a timeout) the 'buffer status' bit and process the data of the panel as soon as this bit gets set. Note that the Goodix panel will send a few spurious interrupts after the 'finger up' event, in which the 'buffer status' bit will never be set.

2017-10-19Input: tca8418 - enable interrupt after it has been requestedDamien Riegel
Currently, enabling keypad interrupts is one of the first operations done on the keypad, even before the interrupt is requested, so there is a small time window where the keypad can fire interrupts but the driver is not yet ready to handle them. It's fine for level interrupts because they will be handled anyway, but not so much for edge ones. This commit modifies and moves the function in charge of configuring the keypad. Enabling interrupts is now the last thing done on the keypad, and after the interrupt has been requested by the driver. Writing to the config register was also used to determine if the device was indeed present on the bus or not, this has been replaced by reading the lock/event count register to keep the same functionality.

2017-10-09Input: synaptics - disable kernel tracking on SMBus devicesAndrew Duggan
In certain situations kernel tracking seems to be getting confused and incorrectly reporting the slot of a contact. On example is when the user does a three finger click or tap and then places two fingers on the touchpad in the same area. The kernel tracking code seems to continue to think that there are three contacts on the touchpad and incorrectly alternates the slot of one of the contacts. The result that is the input subsystem reports a stream of button press and release events as the reported slot changes. Kernel tracking was originally enabled to prevent cursor jumps, but it is unclear how much of an issue kernel jumps actually are. This patch simply disabled kernel tracking for now.

2017-09-29Input: elan_i2c - do not clobber interrupt trigger on x86Dmitry Torokhov
On x86 we historically used falling edge interrupts in the driver because that's how first Chrome devices were configured. They also did not use ACPI to enumerate I2C devices (because back then there was no kernel support for that), so trigger was hard-coded in the driver. However the controller behavior is much more reliable if we use level triggers, and that is how we configured ARM devices, and how want to configure newer x86 devices as well. All newer x86 boxes have their I2C devices enumerated in ACPI. Let's see if platform code (ACPI, DT) described interrupt and specified particular trigger type, and if so, let's use it instead of always clobbering trigger with IRQF_TRIGGER_FALLING. We will still use this trigger type as a fallback if platform code left interrupt trigger unconfigured.
