2019-11-11Input: ili210x - do not set parent device explicitlyDmitry Torokhov1-1/+0
We are using devm_input_allocate_device() that set's up the parent for us, no need to do it ourselves. Tested-by: Adam Ford <[email protected]> #imx6q-logicpd Tested-by: Sven Van Asbroeck <[email protected]> # ILI2118A variant Signed-off-by: Dmitry Torokhov <[email protected]>

2019-11-11Input: ili210x - switch to using threaded IRQDmitry Torokhov1-61/+56
Let's switch the driver to using threaded IRQ so that we do not need to manage the interrupt and work separately, and we do not acknowledge interrupt until we finished handling it completely.

2019-11-11Input: ili210x - add ILI2117 supportMarek Vasut1-1/+45
Add support for ILI2117 touch controller. This controller is similar to the ILI210x and ILI251x, except for the following differences: - Reading out of touch data must happen at most 300 mS after the interrupt line was asserted. No command must be sent, the data are returned upon pure I2C read of 43 bytes long. - Supports 10 simultaneous touch inputs. - Touch data format is slightly different.

2019-11-04Input: synaptics-rmi4 - simplify data read in rmi_f54_workLucas Stach1-32/+16
The body of the for loop is only ever run once as the second standard_report element is never changed from its initial zero init, so the loop condition is never satisfies after the first run. Equally the start member of the first element is never changed from 0, so the index offset is always a constant 0. Remove this needless obfuscation of the code and write it in a straight forward manner.

2019-11-04Input: synaptics-rmi4 - do not consume more data than we have (F11, F12)Andrew Duggan2-4/+4
Currently, rmi_f11_attention() and rmi_f12_attention() functions update the attn_data data pointer and size based on the size of the expected size of the attention data. However, if the actual valid data in the attn buffer is less then the expected value then the updated data pointer will point to memory beyond the end of the attn buffer. Using the calculated valid_bytes instead will prevent this from happening.

2019-11-04Input: synaptics-rmi4 - disable the relative position IRQ in the F12 driverAndrew Duggan1-2/+26
This patch fixes an issue seen on HID touchpads which report finger positions using RMI4 Function 12. The issue manifests itself as spurious button presses as described in: https://www.spinics.net/lists/linux-input/msg58618.html Commit 24d28e4f1271 ("Input: synaptics-rmi4 - convert irq distribution to irq_domain") switched the RMI4 driver to using an irq_domain to handle RMI4 function interrupts. Functions with more then one interrupt now have each interrupt mapped to their own IRQ and IRQ handler. The result of this change is that the F12 IRQ handler was now getting called twice. Once for the absolute data interrupt and once for the relative data interrupt. For HID devices, calling rmi_f12_attention() a second time causes the attn_data data pointer and size to be set incorrectly. When the touchpad button is pressed, F30 will generate an interrupt and attempt to read the F30 data from the invalid attn_data data pointer and report incorrect button events. This patch disables the F12 relative interrupt which prevents rmi_f12_attention() from being called twice.

2019-11-04Input: synaptics-rmi4 - fix video buffer sizeLucas Stach1-1/+1
The video buffer used by the queue is a vb2_v4l2_buffer, not a plain vb2_buffer. Using the wrong type causes the allocation of the buffer storage to be too small, causing a out of bounds write when __init_vb2_v4l2_buffer initializes the buffer.

2019-10-29Input: kxtj9 - switch to using polled mode of input devicesDmitry Torokhov2-122/+37
