From 4f86e1da8184738a29f11fe6713799cc2254305d Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Wed, 20 Sep 2023 16:30:06 -0500 Subject: mb/google/puff: Hide LSPCON device from Windows Puff-based Chromeboxes use a LSPCON for HDMI 2.0 output, but no driver exists or is needed for Windows. Use the devicetree hidden keyword to set the ACPI status to hidden for these devices, to prevent unknown devices from being listed in Windows Device Manager. TEST=build/boot Win11 on google/wyvern, verify no unknown devices in Windows Device Manager for either LSPCON device.
