+    SSDT patch for GPIO Pinning on ELAN1301 trackpad by LeongWZ
+    Confirmed working on OpenCore ASUS UX431FA
+    
+    Compile this .dsl file into .aml file using MaciASL and
+    add .aml file into EFI/OC/ACPI folder.
+    
+    Also, under ACPI->Patch in config.plist,
+    add this dict patch below:
+    
+    (For those using ProperTree, "Find" and "Replace" values found below are in base64
+    and have to be converted into hex values; use base64 to hex converters found online)
