Touchpad After sleep stop working #2
Description
After sleep Touchpad stop working
As we change SHPO (GPDI, Zero) -> SHPO (GPDI, One) to made Touchpad worked,
there's still have warning on the log sudo dmesg | grep -i voodoo
VoodooI2CControllerNub::pci8086,34e8 SSCN not implemented in ACPI tables
VoodooI2CControllerNub::pci8086,34e8 FMCN not implemented in ACPI tables
In OEM DSDT there's SSCN & FMCN
If (USTP) {
Scope (_SB.PCI0.I2C0) {
Method (SSCN, 0, NotSerialized) { Return (PKG3 (SSH0, SSL0, SSD0)) }
Method (FMCN, 0, NotSerialized) { Return (PKG3 (FMH2, FML2, FMD2)) }}}
According #1 VoodooSMBus/VoodooRMI#67 (comment)
the problem seems to be the default clock speed timing of I2C controller
but voodooi2c fine the SSCN & FMCN,
so I change Method SSCN & FMCN to XSCN & XMCN, And add:
External (_SB_.PCI0.I2C3, DeviceObj)
Scope (_SB.PCI0.I2C3)
{
Name (SSCN, Package (0x03) {
0x01B0,
0x01FB,
0x1E
})
Name (FMCN, Package (0x03) {
0x48,
0xA0,
0x1E
})
}
warning on the log about not implemented in ACPI tables is gone,
but after sleep Touchpad still stop working, maybe the value not right
