Subject: [PATCH 2/3] ARM: dts: am33xx-l4: Add missing DMAs for I2C controllers
Date: Thu, 5 Nov 2026 21:05:53 +0100 [thread overview]
Message-ID: <20261105200556.34240-4-apokusinski01@gmail.com> (raw)
In-Reply-To: <20261105200556.34240-2-apokusinski01@gmail.com>
The i2c0 and i2c1 controllers on AM33xx support TX and RX DMA
requests. Add the EDMA request mappings and DMA names for
both controllers.
