2021-02-16Input: rmi4 - remove the need for artificial IRQ in case of HIDBenjamin Tissoires1-50/+74
The IRQ from rmi4 may interfere with the one we currently use on i2c-hid. Given that there is already a need for an external API from rmi4 to forward the attention data, we can, in this particular case rely on a separate workqueue to prevent cursor jumps.

2020-12-07Input: raydium_ts_i2c - do not split tx transactionsFurquan Shaikh1-38/+88
Raydium device does not like splitting of tx transactions into multiple messages - one for the register address and one for the actual data. This results in incorrect behavior on the device side. This change updates raydium_i2c_read and raydium_i2c_write to create i2c_msg arrays separately and passes those arrays into raydium_i2c_xfer which decides based on the address whether the bank switch command should be sent. The bank switch header is still added by raydium_i2c_read and raydium_i2c_write to ensure that all these operations are performed as part of a single I2C transfer. It guarantees that no other transactions are initiated to any other device on the same bus after the bank switch command is sent.

2020-12-01Input: atmel_mxt_ts - fix lost interruptsLinus Walleij1-2/+2
After commit 74d905d2d38a devices requiring the workaround for edge triggered interrupts stopped working. The hardware needs the quirk to be used before even proceeding to check if the quirk is needed because mxt_acquire_irq() is called before mxt_check_retrigen() is called and at this point pending IRQs need to be checked, and if the workaround is not active, all interrupts will be lost from this point. Solve this by switching the calls around.

2020-10-27Input: i8042 - allow insmod to succeed on devices without an i8042 controllerHans de Goede1-1/+11
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.

2020-10-22hil/parisc: Disable HIL driver when it gets stuckHelge Deller2-7/+22
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.

2020-10-05Input: add zinitix touchscreen driverMichael Srba3-0/+594
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 Feng1-2/+2
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.
