Subject: [PATCH v2 0/2] net: macb: fix dma usage
Date: Wed, 29 Nov 2023 10:54:08 +0100 [thread overview]
Message-ID: <20231129-v2023-08-0-topic-macb-v2-0-4dc2cb4d5d25@pengutronix.de> (raw)
The rx_buffer is only dma_alloc'ed but never properly flushed.
Fix that.
While at it, also use proper volatile access instead of sw barriers.
Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de>

Changes in v2:
- change dma_map_single to DMA_FROM_DEVICE
- drop (unsigned long) casts in dma_sync_*
- rework writel/setbits/clearbits to keep semantics
- Link to v1: https://lore.barebox.org/20231128-v2023-08-0-topic-macb-v1-0-9faff73bc990@pengutronix.de
