Subject: [RFC 0/4] Intel Integrated Sensor Hub Support (ISH)
Starting from Cherrytrail, multiple generation of Intel processors offers
on package sensor hub. Several recent tablets, 2-in-1 convertible laptops
are using ISH instead of external sensor hubs. This resulted in lack of
support of sensor function like device rotation and auto backlight
adjustment. In addition, depending on the OEM implementation, support of ISH
is required to support low power sleep states.
The support of ISH on Linux platforms is not new. Android platforms with
Intel SoCs had this support for a while submitted by Daniel Drubin.
This patcheset is reusing most of those changes with clean up and
removing Android platform specific changes.
This series is tested on:
- Lenovo Yoga 260 with Skylake processor
- HP Pavilion x2 detachable with Cherrytrail
The user mode ABI is still same as external sensor hubs using Linux
IIO. So existing user mode software should still work without change.
This series primarily brings in new HID transport used in ISH.
This series submitted as a RFC to try on several devices. We have
received request from Linux users who wanted this support. So I hope all
those users try and give feedback.
