- support for Wake-on-touch in intel-thc (Even Xu)
- support for "Input max input size control" and "Input interrupt delay"
I2C features in order to improve compatibility of THC devices with
legacy HIDI2C touch devices (Even Xu)
|
|
ptl_ddata is local to pci-quicki2c.c, so it'd better be static.

This patch call THC helper functions to enable Wake-on-Touch (WoT)
during driver initialization and disable it when driver is removed.

During customer board enabling, it was found: some touch devices
prepared reset response, but either forgot sending interrupt or
THC missed reset interrupt because of timing issue. THC QuickI2C
driver depends on interrupt to read reset response, in this case,
it will cause driver waiting timeout.
This patch enhances the flow by adding manually reset response
reading after waiting for reset interrupt timeout.

On Panther Lake platform (PTL), THC hardware introduces two new features
for I2C subsystem:
- Input max input size control
- Input interrupt delay
This patch adds above new advanced features into QuickI2C driver, and
enables max input size control feature on PTL to improve QuickI2C
driver compatibility.

This patch defines driver data structure and adds it into QuickI2C
device structure. Changes PCI ID table to use PCI_DEVICE_DATA() to
pass platform specific driver data into driver, let driver has
capability to enable different hardware features according to
different platform driver data.

intel-thc-hid reintroduced the already deprecated PCI API functions
pcim_iomap_table(),
pcim_iomap_regions(),
pcim_iounmap_regions(),
none of which should be used anymore.
Furthermore, calling managed (pcim_*) functions in remove() and probe()
for cleanup is not necessary, since the managed functions clean up
automatically.
Replace / remove the deprecated functions.

Intel QuickI2C driver uses THC hardware to accelerate HID over I2C
(HIDI2C) protocol flow.
This patch implements all data flows described in HID over I2C protocol
SPEC by using THC hardware layer APIs.
