Name: riscv: sophgo: sg2042: Enable PCIe DMA coherence
URL: https://patchwork.kernel.org/project/linux-riscv/list/?series=1075328
Version: 1

Add dma-coherent as an allowed property in the SG2042 PCIe host controller binding. SG2042's PCIe root complexes are cache-coherent with the CPU. Signed-off-by: Han Gao <gaohan@iscas.ac.cn> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>

SG2042's PCIe root complexes are cache-coherent with the CPU. Mark all four PCIe controller nodes (pcie_rc0 through pcie_rc3) as dma-coherent so the kernel uses coherent DMA mappings instead of non-coherent bounce buffering.
