In drivers/hid/, most drivers depend on CONFIG_HID, while a couple of the
drivers in subdirectories instead depend on CONFIG_HID_SUPPORT and use
'select HID'. With the newly added INTEL_THC_HID, this causes a build
warning for a circular dependency:
WARNING: unmet direct dependencies detected for HID
Depends on [m]: HID_SUPPORT [=y] && INPUT [=m]
Selected by [y]:
- INTEL_THC_HID [=y] && HID_SUPPORT [=y] && X86_64 [=y] && PCI [=y] && ACPI [=y]
WARNING: unmet direct dependencies detected for INPUT_FF_MEMLESS
Depends on [m]: INPUT [=m]

- HID_WIIMOTE [=y] && HID_SUPPORT [=y] && HID [=y] && LEDS_CLASS [=y]
- ZEROPLUS_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_ZEROPLUS [=y]
Selected by [m]:
- HID_ACRUX_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_ACRUX [=m]
- HID_EMS_FF [=m] && HID_SUPPORT [=y] && HID [=y]

- PANTHERLORD_FF [=y] && HID_SUPPORT [=y] && HID [=y] && HID_PANTHERLORD [=m]
It's better to be consistent and always use 'depends on HID' for HID
drivers. The notable exception here is USB_KBD/USB_MOUSE, which are
alternative implementations that do not depend on the HID subsystem.
Do this by extending the "if HID" section below, which means that a few
of the duplicate "depends on HID" and "depends on INPUT" statements
can be removed in the process.

THC (Touch Host Controller) is the name of the IP block in PCH that
|
|
interfaces with Touch Devices (ex: touchscreen, touchpad etc.). It
|
|
is comprised of 3 key functional blocks: A natively half-duplex
|
|
Quad I/O capable SPI master; a low latency I2C interface to support
|
|
HIDI2C compliant devices; a hardware sequencer with Read/Write DMA
|
|
capability to system memory.
|
|
|
|
Say Y/M here if you want to support Intel THC. If unsure, say N.
