From 7cfedc8b1b74c7a471685dee6d9494421dc9109e Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Fri, 17 Mar 2017 19:14:20 -0500 Subject: soc/intel/baytrail: add _HRV to GPIO ACPI devices For some reason, the Windows LPEA drivers won't attach without _HRV (hardware version) defined for the GPIO controllers. Add it, using value taken from Intel baytrail/valleyview edk2 reference code. TEST=boot Windows 10/11 on google/rambi, verify LPEA drivers load properly.
