Subject: [PATCH] arm64: dts: realtek: Add RTD syscon compatibles
Date: Tue, 3 Nov 2026 16:43:50 -0600 [thread overview]
Message-ID: <20261103224352.862662-1-robh@kernel.org> (raw)
"syscon" nodes must have specific compatible strings. Specific
compatibles were already added to the bindings. Update the DTS files
with the specific compatibles for the RTD1295, RTD1395 and RTD1619 CRT,
ISO, SB2, misc and SCPU wrapper syscon blocks.
