But according to your words, I need to split ci-hdrc-usb2.yaml into 1 common file and more than 1 vendor specific files (imx, nvidia, qcom, nuvoton and others). In this patchset, I only focus on imx part and KK said he or someone will take over other parts, therefore I just duplicated all the imx compatibles. If I only create imx specific yaml file and remove all compatilbles from common file, nvidia, qcom, nuvoton and others compatible info will be lost, is this feasible? Or should I create mutiple vendor specific files at the same time? Thanks, Xu Yang
