Hi Arnd, Rob, Krzysztof Sorry for being late. I was on vocation in the past several days. As for this as370 removing, I think we'd better keep it. I planned to submit the as370-rdk board dts two years ago, but latter I focused on Synaptics SoCs related drivers support such as gpio, pcie, sdhci and so on. I will send a basic as370 rdk board dts. I'm also considering to mainline basic support for a new SoC. Thanks
