From: James Hastings Subject: support MediaTek interrupt controller To: moosetek4@gmail.com,tech@openbsd.org Date: Sat, 25 Jan 2025 15:21:54 -0500 Add support for MediaTek system interrupt controller. This controller is the default interrupt-parent on older design SoCs. It is located upstream from GIC and sole function is interrupt polarity control. ramdisk console log below. ok?
