Subject: [PATCH v3 2/3] dt-bindings: interrupt-controller: add UltraRISC DP1000 PLIC
Date: Tue, 14 Oct 2025 16:40:56 +0100 [thread overview]
Message-ID: <20251014154100.168236-3-lzampier@redhat.com> (raw)
In-Reply-To: <20251014154100.168236-1-lzampier@redhat.com>
From: Charles Mirabile <cmirabil@redhat.com>
Add compatible strings for the PLIC found in UltraRISC DP1000 SoC.
The PLIC is part of the UR-CP100 core and has a hardware bug requiring
a workaround, so the driver will match on the more generic core-specific
compatible (ultrarisc,cp100-plic) to apply the quirk across all SoCs
using UR-CP100 cores.
