2020-04-01Input: i8042 - add Acer Aspire 5738z to nomux listHans de Goede
The Acer Aspire 5738z has a button to disable (and re-enable) the touchpad next to the touchpad. When this button is pressed a LED underneath indicates that the touchpad is disabled (and an event is send to userspace and GNOME shows its touchpad enabled / disable OSD thingie). So far so good, but after re-enabling the touchpad it no longer works. The laptop does not have an external ps2 port, so mux mode is not needed and disabling mux mode fixes the touchpad no longer working after toggling it off and back on again, so lets add this laptop model to the nomux list.

2020-03-24Input: goodix - fix spurious key release eventsDmitry Mastykin
The goodix panel sends spurious interrupts after a 'finger up' event, which always cause a timeout. We were exiting the interrupt handler by reporting touch_num == 0, but this was still processed as valid and caused the code to use the uninitialised point_data, creating spurious key release events. Report an error from the interrupt handler so as to avoid processing invalid point_data further.

2020-03-24Input: goodix - try to reset the controller if the i2c-test failsHans de Goede
On some ACPI/x86 devices (where we use one of the ACPI IRQ pin access methods) the firmware is buggy, it does not properly reset the controller at boot, and we cannot communicate with it. Normally on ACPI/x86 devices we do not want to reset the controller at probe time since in some cases this causes the controller to loose its configuration and this is loaded into it by the system's firmware. So on these systems we leave the reset_controller_at_probe flag unset, even though we have a access to both the IRQ and reset pins and thus could reset it. In the case of the buggy firmware we have to reset the controller to actually be able to talk to it. This commit adds a special case for this, if the goodix_i2c_test() fails, and we have not reset the controller yet; and we do have a way to reset the controller then retry the i2c-test after resetting the controller. This fixes the driver failing at probe on ACPI/x86 systems with this firmware bug.

For consistency this commit also adds a new GOODIX_CONFIG_GT9X_LENGTH for the length used for recent gt9xx and gt1xxx chips, instead of using GOODIX_CONFIG_MAX_LENGTH for this, so that if other length defines get added in the future it will be clear that the MIN and MAX defines should contain the min and max values of all the other defines.

These devices contain 2 GpioIo resource in their _CRS table, on all 4 such devices which I have access to, the order of the 2 GPIOs is reset, int. Note that the GPIO to which the touchscreen controller irq pin is connected is configured in direct-irq mode on these Bay Trail devices, the pinctrl-baytrail.c driver still allows controlling the pin as a GPIO in this case, but this is not necessarily the case on other X86 ACPI platforms, nor do we have a guarantee that the GPIO order is the same elsewhere, so we limit the use of a _CRS table with 2 GpioIo resources to Bay Trail devices only.

2020-03-24Input: goodix - make resetting the controller at probe independent from the ↵Hans de Goede
GPIO setup Before this commit we would always reset the controller at probe when we have access to the GPIOs which are necessary to do a reset. Doing the reset requires access to the GPIOs, but just because we have access to the GPIOs does not mean that we should always reset the controller at probe. On X86 ACPI platforms the BIOS / UEFI firmware will already have reset the controller and it will have loaded the device specific config into the controller. Doing the reset sometimes causes the controller to lose its configuration, so on X86 ACPI platforms this is not a good idea. This commit adds a new reset_controller_at_probe boolean to control the reset at probe behavior. This commits sets the new bool to true when we set irq_pin_access_method to IRQ_PIN_ACCESS_GPIO, so there are no functional changes.

2020-03-24Input: goodix - make loading the config from disk independent from the GPIO ↵Hans de Goede
setup At least on X86 ACPI platforms it is not necessary to load the touchscreen controller config from disk, if it needs to be loaded this has already been done by the BIOS / UEFI firmware. Even on other (e.g. devicetree) platforms the config-loading as currently done has the issue that the loaded cfg file is based on the controller model, but the actual cfg is device specific, so the cfg files are not part of linux-firmware and this can only work with a device specific OS image which includes the cfg file. And we do not need access to the GPIOs at all to load the config, if we do not have access we can still load the config. So all in all tying the decision to try to load the config from disk to being able to access the GPIOs is not desirable. This commit adds a new load_cfg_from_disk boolean to control the firmware loading instead. This commits sets the new bool to true when we set irq_pin_access_method to IRQ_PIN_ACCESS_GPIO, so there are no functional changes.

2020-03-24Input: goodix - refactor IRQ pin GPIO accessesHans de Goede
Suspending Goodix touchscreens requires changing the interrupt pin to output before sending them a power-down command. Followed by wiggling the interrupt pin to wake the device up, after which it is put back in input mode. So far we have only effectively supported this on devices which use devicetree. On X86 ACPI platforms both looking up the pins; and using a pin as both IRQ and GPIO is a bit more complicated. E.g. on some devices we cannot directly access the IRQ pin as GPIO and we need to call ACPI methods to control it instead. This commit adds a new irq_pin_access_method field to the goodix_chip_data struct and adds goodix_irq_direction_output and goodix_irq_direction_input helpers which together abstract the GPIO accesses to the IRQ pin. This is a preparation patch for adding support for properly suspending the touchscreen on X86 ACPI platforms.

2020-03-20Input: icn8505 - Switch to firmware_request_platform for retreiving the fwHans de Goede
Unfortunately sofar we have been unable to get permission to redistribute icn8505 touchscreen firmwares in linux-firmware. This means that people need to find and install the firmware themselves before the touchscreen will work Some UEFI/x86 tablets with an icn8505 touchscreen have a copy of the fw embedded in their UEFI boot-services code. This commit makes the icn8505 driver use the new firmware_request_platform function, which will fallback to looking for such an embedded copy when direct filesystem lookup fails. This will make the touchscreen work OOTB on devices where there is a fw copy embedded in the UEFI code.

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
