This is just my opinion. :) > If there is a special reason that add example...let me know, plz. I am adding this example just for two reasons 1. There is still some components need to be upstreamed before we add to dts, like pinctrl and regulator, which still need some time. So add here for quick reference after the component is enabled. Had experience before that hip04_eth is merged but dts is delayed, thanks to the document, we can add it quickly. 2. sd has some special requirement of "hisilicon,peripheral-syscon", which used for controlling voltage What do you think?
