Date: Mon, 30 May 2016 21:27:54 -0700 From: Srinivas Pandruvada <srinivas.pandruvada@...ux.intel.com> To: jikos@...nel.org, benjamin.tissoires@...hat.com, jic23@...nel.org Cc: linux-input@...r.kernel.org, linux-iio@...r.kernel.org, linux-kernel@...r.kernel.org, chaya.golan@...el.com, daniel.drubin@...el.com, Srinivas Pandruvada <srinivas.pandruvada@...ux.intel.com> 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.
