[...] > base-commit: b44251a8c179381b9f3ed3aa49be04fe1d516903 Hi, Jun. The display of my sm8650 device requires 4:4:2(lm, dsc, intf) topology, I want to test this series, these patches can't be applied to the latest linux-next tree, and I can't find the commit id in linux-next or msm-next. Where can I fetch the tree? Best wishes, Pengyu
