This patchset fixes bug people found on hikey960 when allocating DMA channels to peripherals such as SPI. It fails because the channel is reserved and not accessible by kernel.
Patch 1, 2 and 3 add support to reserved channels for K3 DMA. Patch 4 includes a removal of axi_config who controls DMA secure/non-secure access permission but is actually set in early stage by bootloader.
