Subject: [PATCH 0/2] dmaengine: ma35d1-pdma: Add MA35D1 PDMA driver
Date: Tue, 3 Nov 2026 10:22:00 +0800 [thread overview]
Message-ID: <20261103022202.2139674-1-shanchun1218@gmail.com> (raw)
This series adds the PDMA controller driver and DT binding for the
Nuvoton MA35D1 SoC.
The driver supports memcpy, slave scatter-gather and cyclic transfers,
and a per-channel timeout configured through
dma_slave_config.peripheral_config. The timeout is needed by the
MA35D1 UART driver, to be submitted separately.
Tested on the MA35D1 SOM board with Linux v7.4-rc1, using local
(not yet submitted) QSPI and UART patches that use this PDMA driver.
