I made all changes... i removed kext from sle and reinstalled to le... i made even other points... rebooted but still the same issue to touch...

From your kernel log:
kernel: (VoodooI2C) VoodooI2CControllerDriver::VoodooI2CDeviceNub Warning: Incompatible APIC interrupt pin (0x5f > 0x2f) and no GPIO interrupts found; if your chosen satellite implements polling then VoodooI2CDeviceNub will run in polling mode.
Click to expand...
You should patch your DSDT (ETPD device) for GPIO interrupts (Add SBFG, set correct GPIO pin, change the return statement of _CRS to SBFB, SBFG instead of SBFB, SBFI)
 
dsdt.dsl is my vanilla dsdt,

from above picture, i know i should use the HID Satellite Kexts,
and my APIC pin is 33, so the pin list is 0x1B or 0x7B
am i correct, but i dont know how to apply those patches, can someone lead me?
device "\\_SB.PCI0.I2C0" but the picture above seems wrong.
i'm trying to get polling mode working

My touchpad can use as a simple mouse, left click and right click. But can't use Mutil touch.
And trackpad not showing up in System Preferences.

Don't put an explicit pin number in SBFG, leave it 0. There's also no need to remove SBFI.
Just patch _CRS to this (you didn't do it):
Code: 
Return (ConcatenateResTemplate (SBFB, SBFG))

If you need more help, attach a full troubleshooting archive made with gen_debug.sh.

While your touchscreen requires VoodooI2CHID.kext, your trackpad only works as a mouse with this kext.
Install VoodooI2CELAN.kext too, to have multitouch capability for your trackpad.
 
On my laptop I can't get it to work, the touchpad just doesn't respond at all and as soon as I touch it the keyboard stops working as well (it's PS2 and I've got VoodooPS2Controller.kext installed).
I'm on Skylake and looking at the log.txt I can see the "Unknown Synopsys component type: 0xffffffff" error, but unfortunately if I try to apply the I2C controllers patch in DSDT I get a lot of errors when compiling (see the attached screenshots).

A BIOS update may change the DSDT structure and you won't need the patch. In this case, re-extract and re-patch DSDT after the update, obviously.
Anyway, you can manually apply the patch (your DSDT doesn't look like other Skylake DSDTs...):
Change this code:
Code: 
    Scope (_SB.PCI0)
    {
        Device (I2C0)
        {
            Name (LINK, "\\_SB.PCI0.I2C0")
        }
    }

    If (LNotEqual (SMD0, 0x02))
    {
        Scope (_SB.PCI0.I2C0)
        {
            Name (_HID, "INT3442")  // _HID: Hardware ID
            Method (_HRV, 0, NotSerialized)  // _HRV: Hardware Revision
            {
                Return (LHRV (SB10))
            }

            Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
            {
                Return (LCRS (SMD0, SB00, SIR0))
            }

            Method (_PSC, 0, NotSerialized)  // _PSC: Power State Current
            {
                GETD (SB10)
            }

            Method (_PS0, 0, NotSerialized)  // _PS0: Power State 0
            {
                LPD0 (SB10)
            }

            Method (_PS3, 0, NotSerialized)  // _PS3: Power State 3
            {
                LPD3 (SB10)
            }

            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                Return (LSTA (SMD0))
            }
        }
    }

    If (LEqual (SMD0, 0x02))
    {
        Scope (_SB.PCI0.I2C0)
        {
            Name (_ADR, 0x00150000)  // _ADR: Address
            Method (_DSM, 4, Serialized)  // _DSM: Device-Specific Method
            {
                If (PCIC (Arg0))
                {
                    Return (PCID (Arg0, Arg1, Arg2, Arg3))
                }

                Return (Zero)
            }
        }
    }
To this:
Code: 
    Scope (_SB.PCI0)
    {
        Device (I2C0)
        {
            Name (LINK, "\\_SB.PCI0.I2C0")
            Method (_PSC, 0, NotSerialized)  // _PSC: Power State Current
            {
                GETD (SB10)
            }

            Method (_PS0, 0, NotSerialized)  // _PS0: Power State 0
            {
                LPD0 (SB10)
            }

            Method (_PS3, 0, NotSerialized)  // _PS3: Power State 3
            {
                LPD3 (SB10)
            }
        }
    }

    If (LNotEqual (SMD0, 0x02))
    {
        Scope (_SB.PCI0.I2C0)
        {
            Name (_HID, "INT3442")  // _HID: Hardware ID
            Method (_HRV, 0, NotSerialized)  // _HRV: Hardware Revision
            {
                Return (LHRV (SB10))
            }

            Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
            {
                Return (LCRS (SMD0, SB00, SIR0))
            }

            Method (_STA, 0, NotSerialized)  // _STA: Status
            {
                Return (LSTA (SMD0))
            }
        }
    }

    If (LEqual (SMD0, 0x02))
    {
        Scope (_SB.PCI0.I2C0)
        {
            Name (_ADR, 0x00150000)  // _ADR: Address
            Method (_DSM, 4, Serialized)  // _DSM: Device-Specific Method
            {
                If (PCIC (Arg0))
                {
                    Return (PCID (Arg0, Arg1, Arg2, Arg3))
                }

                Return (Zero)
            }
        }
    }

Remove DSDT.aml from Clover/ACPI. You should only put it in Clover/ACPI/patched.
No OS patch applied, use Windows 2015 (Windows 10) patch.
