Unfortunately, I'm still encountering a bit of trouble getting the chipset to respond on my Lenovo Yoga 460/ Yoga 14. I've applied the newest patches to Kernel 4.6.0 sources (commit #2dcd0af5, with Ubuntu patches applied), no errors during compilation, but the system does not yet recognize the chipset. There were no errors observed during kernel compilation, yet the "modules.builtin" file that was created made no mention of the driver. Please let me know if that's something that I can ignore in this case. There were no mentions of the driver during boot, and only the minimal mention of device "9d35" during the PCI bus scan at boot. There is also no mention of at /sys/bus/iio directory after boot. Spoofing different OSes via the acpi_osi boot option (used "Windows 2015". "Windows 2012", "Linux") made no change in behavior. Here's a copy of the current output from lspci: 00:13.0 Non-VGA unclassified device: Intel Corporation Device 9d35 (rev 21) Subsystem: Lenovo Device 504c Control: I/O- Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Interrupt: pin A routed to IRQ 255 Region 0: Memory at d564b000 (64-bit, non-prefetchable) [disabled] [size=4K] Capabilities: [80] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- Let me know if there's any other information that I can provide, and I'll be happy to do so.
