Hi Bharat, Thank you for sending the patches over!

[...] 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
