HID: intel_ish-hid: ISH Transport layer 



The ISH transport layer (ishtp) is a bi-directional protocol implemented
on the top of PCI based inter processor communication layer. This layer
offers:
- Connection management
- Flow control with the firmware
- Multiple client sessions
- Client message transfer
- Client message reception
- DMA for RX and TX for fast data transfer

Refer to Documentation/hid/intel-ish-hid.txt for
overview of the functionality implemented in this layer.

	help

	  The Integrated Sensor Hub (ISH) enables the ability to offload

	  sensor polling and algorithm processing to a dedicated low power

	  processor in the chipset. This allows the core processor to go into

	  low power modes more often, resulting in the increased battery life.

	  The current processors that support ISH are: Cherrytrail, Skylake,

	  Broxton and Kaby Lake.



	  Say Y here if you want to support Intel ISH. If unsure, say N.
