NOT FOR kernel v5.1. v2 - Rebased on the top of "HID: intel-ish: enable raw interface to HID devices on ISH" which Jiri already applied. - Also exported devc pointer for DMA No functional changes are expected with this series. I am posting this now because of usage of ISH in ChromeOS Embedded Controller. https://lkml.org/lkml/2019/2/24/26 I want to make sure that API is restricted before more development and posting there. Currently only one ISH client is using ISH transport. But it is changing now with the development of other clients using ISH transport. Some of these clients which are targeted for Linux based OS only laptops, are not using HID to export sensors. As more clients are getting developed it is important that the external interface for ISH transport only allows what clients need. Currently the header files used by clients "client.h" and "ishtp-dev.h" include other ISH header files. Also clients access fields from structure which also has other fields which are only used by ISH transort. So this series introduces one header file "linux/intel-ish-client-if.h". This header files doesn't include any other ISH transport header files. There are interface functions defined so that clients never have to directly access any ISH transort structures. Also clients don't have to match there GUID in probe. They will be only probbed if their GUID matches, which is passed as driver registry.
