Subject: [PATCH v2 0/9] add fsl-edma3 support
Date: Wed, 15 Jul 2020 01:41:39 +0800 [thread overview]
Message-ID: <1594748508-22179-1-git-send-email-yibin.gong@nxp.com> (raw)
This patchset enable fsl-edma3 which is used on i.mx8qxp/i.mx8qm. There
are big changes on fsl-edma so that add indepent fsl-edma3 here:
1. split memory address for per channel, while all channels share the same
memory address and the same control registers CR/INT..etc.
2. all TCD registers of channels are continuous on legacy edma but split on
edma3.
3. per interrupt per channel on edma3.
4. totally different register layer and add some register such as SBR
5. power domain support, per domain per channel.
The first 4 patches are used for preparing no any function changes involed.
v2:
1. fix yaml binding doc build warning.
Robin Gong (9):
dmaengine: fsl-edma: move edma_request functions into drvdata
dmaengine: fsl-edma-common: add condition check for fsl_edma_chan_mux
dmaengine: fsl-edma-common: add fsl_chan into fsl_edma_fill_tcd
dmaengine: fsl-edma-common: export fsl_edma_set_tcd_regs
dmaengine: fsl-edma3: add fsl-edma3 driver
dt-bindings: dma: add fsl-edma3 yaml
firmware: imx: scu-pd: correct dma resource
