Subject: [PATCH v2] mtd: nand: raw: atmel: Add message on DMA usage
Date: Wed, 21 Aug 2024 16:20:05 +0200	[thread overview]
Message-ID: <20240821142006.645306-1-ada@thorsis.com> (raw)

Like for other atmel drivers (serial, crypto, mmc, …), too.

Signed-off-by: Alexander Dahl <ada@thorsis.com>

Notes:
    v1 -> v2:
    - make info message conditional (thanks Miquel)
