Date: Sun, 9 Oct 2022 21:13:35 +0300 Message-Id: <20221009181338.2896660-7-lis8215@gmail.com> X-Mailer: git-send-email 2.36.1 In-Reply-To: <20221009181338.2896660-1-lis8215@gmail.com> References: <20221009181338.2896660-1-lis8215@gmail.com> MIME-Version: 1.0 To: unlisted-recipients:; (no To-header on input) Precedence: bulk List-ID: X-Mailing-List: linux-serial@vger.kernel.org The JZ4755 has 4 DMA channels per DMA unit, two idential DMA units. The JZ4755 has the similar DMA engine to JZ4725b, so I assume it has the same bug as JZ4725b, see commit a40c94be2336.
