Input: cyapa - fix setting suspend scan rate

2015-04-20T17:30:09+00:00

The suspend scan rate value should not exceed 1000, unfortunately when
implementing the limit we used max_t instead of min_t, causing the value to
be at least 1000.

Input: cyapa - off by one in cyapa_update_fw_store()

2015-01-22T16:23:15+00:00

If "(count == NAME_MAX)" then we could end up putting the NUL terminator
one space beyond the end of the fw_name[] array.

Input: cyapa - add acpi device id support

2015-01-18T08:10:33+00:00

Add acpi device tree support.
acpi device id "CYAP0000" is for old gen3 trackpad devices.
acpi device id "CYAP0001" is for new gen5 trackpad devices.

Input: cyapa - add sysfs interfaces support in the cyapa driver

2015-01-18T08:10:30+00:00

Introduce control interfaces that are commonly used in pre- and after
production, for trackpad device state checking, managing and firmware image
updating.  These interfaces include mode, firmware_version and product_id
interfaces for reading firmware version and trackpad device product id
values, and update_fw interface to command firmware image update process.
There are also baseline and calibrate interfaces for reading and checking
trackpad device's sensors states.

Input: cyapa - add runtime power management support

2015-01-18T08:10:29+00:00

This change implements runtime PM support in the driver and adds
runtime_suspend_scanrate_ms power management interface in device's power
group, so users or applications can control the runtime power management
strategy of trackpad device according to their requirements.

Input: cyapa - add gen5 trackpad device basic functions support

2015-01-18T08:10:28+00:00

This change adds support for Gen5 Cypress trackpads. The driver detects
generation of the device at probe time and automatically selects
appropriate protocol.

Input: cyapa - re-design driver to support multi-trackpad in one driver

2015-01-18T08:10:28+00:00

In order to support multiple different chipsets and communication protocols
trackpad devices in one cyapa driver, the new cyapa driver is re-designed
with one cyapa driver core and multiple device specific functions component.
The cyapa driver core is contained in this patch, it supplies basic functions
that working with kernel and input subsystem, and also supplies the interfaces
that the specific devices' component can connect and work together with as
one driver.

Chage b1cfa7b4388285c0f0b486f152ab0cb18612c779 tried to get away form using
irq in cyapa structure and use client->irq instead, but missed a couple of
spots making the touchpad inoperative after resume.
