Hi Bharat, Thank you for sending the patches over! > Add support for routing PCIe DMA traffic coherently when > Cache Coherent Interconnect (CCI) is enabled in the system. > The "dma-coherent" property is used to determine if CCI is enabled > or not. > Refer https://developer.arm.com/documentation/ddi0470/k/preface > for CCI specification. [...] A small nitpick, so feel free to ignore, of course. Perhaps "Refer to" and "for the CCI", etc. [...] > + /* This routes the PCIe DMA traffic to go through CCI path */ > + if (of_dma_is_coherent(dev->of_node)) { > + nwl_bridge_writel(pcie, nwl_bridge_readl(pcie, BRCFG_PCIE_RX1) | > + CFG_PCIE_CACHE, BRCFG_PCIE_RX1); > + } [...] A suggestion. You can drop the curly brackets here if you want to keep the style used in the kernel, especially for when there is a single statement inside the code block. Krzysztof
