From: Conor Dooley Date: Tue, 5 Jul 2022 21:52:04 +0000 (+0100) Subject: dt-bindings: dma: dw-axi-dmac: extend the number of interrupts X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4ce653d7c651d6a9fc6d5db4275624ac8d856b99;p=linux.git dt-bindings: dma: dw-axi-dmac: extend the number of interrupts The Canaan k210 apparently has a Sysnopsys Designware AXI DMA controller, but according to the documentation & devicetree it has 6 interrupts rather than the standard one. Support the 6 interrupt configuration by unconditionally extending the binding to a maximum of 8 per-channel interrupts thereby matching the number of possible channels.
