Can you do: ls -l /sys/bus/platform/devices | grep ELAN066C and let me know the output of that ? If that confirms that a platform device is being instantiated then the issue likely is that neither of the 2 if-s here: Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings { Name (SBFG, ResourceTemplate () { GpioInt (Level, ActiveLow, ExclusiveAndWake, PullUp, 0x0000, "\\_SB.GPIO", 0x00, ResourceConsumer, , ) { // Pin list 0x0009 } }) If ((^^^PCI0.LPC0.H_EC.ECRD (RefOf (^^^PCI0.LPC0.H_EC.TPTY)) == 0x01)) { Name (SBFB, ResourceTemplate () { I2cSerialBusV2 (0x0015, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\_SB.I2CD", 0x00, ResourceConsumer, , Exclusive, ) }) Return (ConcatenateResTemplate (SBFB, SBFG)) } If ((^^^PCI0.LPC0.H_EC.ECRD (RefOf (^^^PCI0.LPC0.H_EC.TPTY)) == 0x02)) { Name (SBFC, ResourceTemplate () { I2cSerialBusV2 (0x002C, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\_SB.I2CD", 0x00, ResourceConsumer, , Exclusive, ) }) Return (ConcatenateResTemplate (SBFC, SBFG)) } } Returns true causing no i2c-client to get instantiated. If that is the case the first thing to do is try a DSDT overlay replacing the first if: If ((^^^PCI0.LPC0.H_EC.ECRD (RefOf (^^^PCI0.LPC0.H_EC.TPTY)) == 0x01)) { ... } With dropping the If so you get: { ... } See: https://docs.kernel.org/admin-guide/acpi/initrd_table_override.html And then specifically the "How does it work" section.
