Subject: [PATCH 1/7] watchdog: mtk_wdt: add explicit compatibles for SoCs using mt6589 fallback
Date: Fri, 17 Jul 2026 01:19:17 +0900	[thread overview]
Message-ID: <20260716161923.266315-2-akkun11.open@gmail.com> (raw)
In-Reply-To: <20260716161923.266315-1-akkun11.open@gmail.com>

Several SoCs currently rely on matching "mediatek,mt6589-wdt" via the
fallback compatible. Add dedicated of_device_id entries for each of
them so that the driver can match directly on the SoC-specific string.

This is a prerequisite for DTS to safely drop the fallback string.
