SteamDeckGyroDSU works really well for motion controls with both Yuzu and Ryujinx.

As an alternative, you can check out the Genki Covert Dock and Covert Dock Mini that work well with the Switch and the Deck and are really small, so great for traveling.
Unfortunately they’re rated for 25W and 20W respectively, while the Deck usually requires 38W for full-speed charge, so it won’t charge as well as the official Valve dock and it doesn’t have power pass-through.
