@ -60,12 +60,6 @@ If the driver needs to perform more complex initialization like getting and
configuring GPIOs it can get its ACPI handle and extract this information
from ACPI tables.
Currently the kernel is not able to automatically determine from which ACPI
device it should make the corresponding platform device so we need to add
the ACPI device explicitly to acpi_platform_device_ids list defined in
drivers/acpi/acpi_platform.c. This limitation is only for the platform
devices, SPI and I2C devices are created automatically as described below.
DMA support

DMA controllers enumerated via ACPI should be registered in the system to

If INPUT_PROP_SEMI_MT is not set, the device is assumed to be a true MT
device.
INPUT_PROP_TOPBUTTONPAD:
-----------------------
Some laptops, most notably the Lenovo *40 series provide a trackstick
device but do not have physical buttons associated with the trackstick
device. Instead, the top area of the touchpad is marked to show
visual/haptic areas for left, middle, right buttons intended to be used
with the trackstick.
If INPUT_PROP_TOPBUTTONPAD is set, userspace should emulate buttons
accordingly. This property does not affect kernel behavior.
The kernel does not provide button emulation for such devices but treats
them as any other INPUT_PROP_BUTTONPAD device.
Guidelines:
==========
The guidelines below ensure proper single-touch and multi-finger functionality.
