Hi all,The PC Engines APU2/3/4 mainline firmware was updated this week and they've enabled ACPI GPIO calls as well as IOMMU support. I saw tech@ got a patch for apugpio in March, maybe it could be updated to use ACPI?
Link to firmware is here: https://pcengines.github.io/?utm_source=PC+Engines+Open+Source+Firmware+Release&utm_campaign=8e5255d4da-EMAIL_CAMPAIGN_2019_05_10_09_20_COPY_01&utm_medium=email&utm_term=0_b9727cda45-8e5255d4da-48008233
Cheers, Noth
