Thank you Andy, appreciate it.

I have two more series in queue, QCS404 DTS series https://patchwork.kernel.org/project/linux-arm-msm/list/?series=40841
and QCS404 defconfigs https://patchwork.kernel.org/project/linux-arm-msm/list/?series=40853

Would be great if you can review these as well

Regards
