Hi, Biwen Looking forward for your patch - http://patchwork.ozlabs.org/patch/1203640/, though would like to know following: - Do you plan anything else on this PATCH? There is no update since March beginning. I might help with it if you give me instructions what's left on your plate. - What is the git commit hash your patch's based on? I tried to apply patch to the latest mainline (see below), but got 1 part of patch failed, but fixed it manually. commit c0cc271173b2e1c2d8d0ceaef14e4dfa79eefc0d - Would be helpful if anyone share which kernel builder (Yocto or NXP's flex-builder) you use for this driver. Thanks
