Subject: [PATCH v9 13/15] ARM: dts: aspeed: anacapa: Remove LTC4287 power monitors
Date: Wed, 30 Sep 2026 14:10:21 +0800	[thread overview]
Message-ID: <20260930-anacapa-devlop-phase-devicetree-v9-13-f08aa0d7182d@gmail.com> (raw)
In-Reply-To: <20260930-anacapa-devlop-phase-devicetree-v9-0-f08aa0d7182d@gmail.com>

From: Carl Lee <carl.lee@amd.com>

The LTC4287 power-monitor nodes in the Anacapa DTS overlap I2C
addresses used by other devices on the same buses.

Keeping these nodes may cause incorrect probing/binding attempts.
Remove them to avoid address conflicts.
