Add PDMA driver, sf-pdma, to enable DMA engine on HiFive Unleashed Rev A00 board. - Implement dmaengine APIs, support MEM_TO_MEM async copy. - Tested by DMA Test client - Supports 4 channels DMA, each channel has 1 done and 1 err interrupt connected to platform-level interrupt controller (PLIC). - Depends on DMA_ENGINE and DMA_VIRTUAL_CHANNELS The datasheet is here: https://static.dev.sifive.com/FU540-C000-v1.0.pdf Follow the DMAengine controller doc, "./Documentation/driver-api/dmaengine/provider.rst" to implement DMA engine. And use the dma test client in doc, "./Documentation/driver-api/dmaengine/dmatest.rst", to test. Each DMA channel has separate HW regs and support done and error ISRs. 4 channels share 1 done and 1 err ISRs. There's no expander/arbitrator in DMA HW. ------ ------ | |--< done 23 >--|ch 0| | |--< err 24 >--| | (dma0chan0) | | ------ | | ------ | |--< done 25 >--|ch 1| | |--< err 26 >--| | (dma0chan1) |PLIC| ------ | | ------ | |--< done 27 >--|ch 2| | |--< err 28 >--| | (dma0chan2) | | ------ | | ------ | |--< done 29 >--|ch 3| | |--< err 30 >--| | (dma0chan3) ------ ------ Signed-off-by: Green Wan <green.wan@sifive.com> Link: https://lore.kernel.org/r/20191107084955.7580-4-green.wan@sifive.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
