Subject: Re: [Upstream] [PATCH v7 3/3] arm64: dts:
 imx8mm-phyboard-polis-peb-av-10: Set lvds-vod-swing

Hi,

is there anything else I need to do, or can this patch now be applied?

The initial two patches that introduce property support have already 
been merged, and the patch series that this patch depends on [1] has 
also been applied.

Best regards,
Andrej
