Hi Shawn,

I noticed this and several other of my pending patches delegated to
you got marked as 'archived' and no longer appear as new in my
patchwork queue [1]. I wanted to make sure they are still in your
queue or see if I need to resubmit them. I'm not sure what the process
is that you follow and if they got archived by you or something else.
Please let me know if I need to do anything:

arm64: dts: imx8mm: add imx8mm-venice-gw73xx-0x-rpidsi overlay for display
arm64: dts: freescale: fix imx8mm-venice-gw72xx-0x-imx219 overlay
