2020-11-17Input: ads7846 - fix integer overflow on Rt calculationOleksij Rempel
In some rare cases the 32 bit Rt value will overflow if z2 and x is max, z1 is minimal value and x_plate_ohms is relatively high (for example 800 ohm). This would happen on some screen age with low pressure. There are two possible fixes: - make Rt 64bit - reorder calculation to avoid overflow The second variant seems to be preferable, since 64 bit calculation on 32 bit system is a bit more expensive.

Starting with 3eac5c7e44f3 ("Input: ads7846 - extend the driver for ads7845 controller support"), the ads7845 was partially converted to full duplex mode. Since it is not touchscreen controller specific, it is better to extend this conversion to cover entire driver. This will reduce CPU load and make driver more readable.

2020-10-26Input: i8042 - allow insmod to succeed on devices without an i8042 controllerHans de Goede
The i8042 module exports several symbols which may be used by other modules. Before this commit it would refuse to load (when built as a module itself) on systems without an i8042 controller. This is a problem specifically for the asus-nb-wmi module. Many Asus laptops support the Asus WMI interface. Some of them have an i8042 controller and need to use i8042_install_filter() to filter some kbd events. Other models do not have an i8042 controller (e.g. they use an USB attached kbd). Before this commit the asus-nb-wmi driver could not be loaded on Asus models without an i8042 controller, when the i8042 code was built as a module (as Arch Linux does) because the module_init function of the i8042 module would fail with -ENODEV and thus the i8042_install_filter symbol could not be loaded. This commit fixes this by exiting from module_init with a return code of 0 if no controller is found. It also adds a i8042_present bool to make the module_exit function a no-op in this case and also adds a check for i8042_present to the exported i8042_command function. The latter i8042_present check should not really be necessary because when builtin that function can already be used on systems without an i8042 controller, but better safe then sorry.

In particular: - Remove non-DT i.MX platforms that haven't seen activity in years, it's time to remove them. - A bunch of cleanup and removal of platform data for TI/OMAP platforms, moving over to genpd for power/reset control (yay!) - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them closer to multiplatform support (not quite there yet, but getting close).

2020-10-22hil/parisc: Disable HIL driver when it gets stuckHelge Deller
When starting a HP machine with HIL driver but without an HIL keyboard or HIL mouse attached, it may happen that data written to the HIL loop gets stuck (e.g. because the transaction queue is full). Usually one will then have to reboot the machine because all you see is and endless output of: Transaction add failed: transaction already queued? In the higher layers hp_sdc_enqueue_transaction() is called to queued up a HIL packet. This function returns an error code, and this patch adds the necessary checks for this return code and disables the HIL driver if further packets can't be sent. Tested on a HP 730 and a HP 715/64 machine. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org>

All evdev clients share a common waitgroup. On new input events, all clients waiting on this waitgroup are woken up, even those filtering out the events, possibly more than once per event. This leads to duplicated and unwanted wakeups. Split the shared waitgroup into per-client waitgroups for more fine-grained wakeups.

2020-10-04Input: add zinitix touchscreen driverMichael Srba
Add support for the bt541 touchscreen IC from zinitix, loosely based on downstream driver. The driver currently supports multitouch (5 touch points). The bt541 seems to support touch keys, but the support was not added because that functionality is not being utilized by the touchscreen used for testing. Based on the similartities between downstream drivers, it seems likely that other similar touchscreen ICs can be supported with this driver in the future.

2020-09-28Input: hyperv-keyboard: Use VMBUS_RING_SIZE() for ringbuffer sizesBoqun Feng
For a Hyper-V vmbus, the size of the ringbuffer has two requirements: 1) it has to take one PAGE_SIZE for the header 2) it has to be PAGE_SIZE aligned so that double-mapping can work VMBUS_RING_SIZE() could calculate a correct ringbuffer size which fulfills both requirements, therefore use it to make sure vmbus work when PAGE_SIZE != HV_HYP_PAGE_SIZE (4K). Note that since the argument for VMBUS_RING_SIZE() is the size of payload (data part), so it will be minus 4k (the size of header when PAGE_SIZE = 4k) than the original value to keep the ringbuffer total size unchanged when PAGE_SIZE = 4k.
