--- Comment #15 from Mateusz Kaduk (mateusz.ka...@gmail.com) --- Follow up, apparently this TouchPad device was added to intel-lpss https://lore.kernel.org/all/20220211145055.992179-1-jarkko.nik...@linux.intel.com/ Indicated by line: + { PCI_VDEVICE(INTEL, 0x7a7d), (kernel_ulong_t)&bxt_i2c_info }, However dmesg | grep lpss shows intel-lpss: probe of 0000:00:19.0 failed with error -22 intel-lpss 0000:00:19.1: enabling device (0004 -> 0006) intel-lpss 0000:00:19.1: can't derive routing for PCI INT B intel-lpss 0000:00:19.1: PCI INT B: not connected intel-lpss: probe of 0000:00:19.1 failed with error -22 Bus 0000:00:19.1 is where the windows driver attaches and Lenovo's Linux diagnostic tool. Maybe it's possible to follow https://lwn.net/Articles/143397/ to unbind 0000:19.1 from the intel-lpss-pci device and bind it to the i2c_designware driver, but I don't know yet how to do that. Anyways, I am sure sure if this thread gets required attention from developers, or anyone able to help, so maybe switching back to Lenovo forum can get us some help? -- You may reply to this email to add a comment.
