Subject: [PATCH 00/12] Add support for BCM2712 DMA engine
Date: Sun, 4 Feb 2024 07:59:28 +0100 [thread overview]
Message-ID: <cover.1706948717.git.andrea.porta@suse.com> (raw)
This patchset aims to update the dma engine for BCM* chipset with respect
to current advancements in downstream vendor tree. In particular:
* Added support for BCM2712 DMA.
* Extended DMA addressing to 40 bit. Since BCM2711 also supports 40 bit addressing,
it will also benefit from the update.
* Handled the devicetree node from vendor dts (e.g. "dma40").
The only difference between the application of this patch and the relative code
in vendor tree is the dropping of channel reservation for BCM2708 DMA legacy
driver, that seems to have not made its way to upstream anyway, and it's
probably used only from deprecated subsystems.
Compile tested and runtime tested on RPi4B only.
Dom Cobley (4):
bcm2835-dma: Support dma flags for multi-beat burst
bcm2835-dma: Need to keep PROT bits set in CS on 40bit controller
dmaengine: bcm2835: Rename to_bcm2711_cbaddr to to_40bit_cbaddr
bcm2835-dma: Fixes for dma_abort
Maxime Ripard (2):
dmaengine: bcm2835: Use to_bcm2711_cbaddr where relevant
dmaengine: bcm2835: Support DMA-Lite channels
Phil Elwell (6):
bcm2835-dma: Add support for per-channel flags
bcm2835-dma: Add proper 40-bit DMA support
bcm2835-dma: Add NO_WAIT_RESP, DMA_WIDE_SOURCE and DMA_WIDE_DEST flag
bcm2835-dma: Advertise the full DMA range
bcm2835-dma: Derive slave DMA addresses correctly
