Change log v4: - Replace Bus PM suspend/resume callbacks to pm_ops calls to support callbacks from hibernate as pointer by Rafael - Fix kernel doc style comments: Now every function has kernel doc header - All checkpatch errors are resolved - Function returning just a single value with no users of return value to void - reference_count in struct ishtp_cl_device changed to bool as pointed by Ooi, Joyce - auto module load glue logic as suggested by Ooi, Joyce - Fix possible kernel warnings during module removal in ishtp - Remove devices during ish-pci module removal - Add Original-author tag - Add MAINTAINER entry v3: - Rebased to linux-next as there are some new bus ids are added to linux-next - Documentation changes suggested by Jonathan - The PCI device name for BXTP is changed to APL - Added module parameter to enable DMA as some older FW have issues in DMA support. - On resume just restart to resume faster insted of reset for S3 compliant platforms Thanks to Grant Likely and Atri Bhattacharya, Rann Bar and Ooi Joyce for test. I will add Tested-by to commits for the final version of the patches. v2: - Overview in documentation show analogy with usbhid implementation - sparse errors for statics. Also pointed by Jiri - Clearly marking exported function header file. Clean up all exports unused inteface functions - Changed to tristate from boolean as pointed by Jiri: this required remove/unload functions - Prevent crash when ISH enabled on non supported platform - Break client.c to smaller part by seprating buffer allocations - move bus register/unregister to ishtp module - There is only one config symbol INTEL_ISH_HID, removed silent config for TRANSPORT and IPC 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. The user mode ABI is still same as external sensor hubs using Linux IIO. So existing user mode software should still work. This series primarily brings in new HID transport used in ISH. Thanks to the community members who tested RFC patches and provided feedback. For users testing on Linux distributions using IIO sensor proxy, a short term work around is required till we have debugged this issue.
