DSDT with WADR workaround

To get the sd card reader and wifi (over sdio) to work on Asus T100HA (cherry trail based) computer you have to modify the DSDT.

I've not figured out the work around myself, but here is a description on the work around:

--
after lots of debugging I have wifi working under Linux. The problem is in ACPI DSDT table. The SB.PCI0.SDHB._ADR method returns 0, which is no unique. The makes Linux to guess how to glue devices together (see acpi_find_child_device in drivers/acpi/glue.c) and it ends wrong. The fix for DSDT, which helped me, is here https://github.com/p-an/T100HA-DSDT/...fdce6570537c96 (you can try this one, but better is to dump you own and fix that one).

(Note this post says that there is fix in later bios updates from Asus, but that is wrong.)

Here is what needs to be done:
--
         Device (SDHB)
         {
-            Name (_ADR, Zero)  // _ADR: Address
+            Name (WADR, Zero)  // _ADR: Address
             Name (_HID, "80860F14" /* Intel Baytrail SDIO/MMC Host Controller */)  // _HID: Hardware ID
             Name (AHID, "INT33BB")
             Name (_CID, "PNP0D40" /* SDA Standard Compliant SD Host Controller */)  // _CID: Compatible ID
