Subject: [PATCH 3/4] ARM: dts: microchip: use recent scl/sda gpio bindings
Date: Mon, 19 May 2025 13:21:05 +0200 [thread overview]
Message-ID: <20250519112107.2980-4-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20250519112107.2980-1-wsa+renesas@sang-engineering.com>
We have dedictaded bindings for scl/sda nowadays. Switch away from the
deprecated plain 'gpios' property.
