This is a Dell Wyse thin client, variously referred to as "Ariel", "3020" or "Tx0D" where "x" stands for the software it was shipped with. I somewhat arbitrarily chose "ariel". There are bits missing, because the drivers are not in and bindings are not settled yet: * Things missing from mmp3.dtsi: HSIC controller and its PHY (only the internal Ethernet is connected here, the hub with external USB2 ports is connected to the U2O controller that works well), Vivante GC2000 GPU * &twsi1/regulator@19 Marvell 88pm867 power regulator * &twsi3/vga-dvi-encoder@76 Chrontel CH7033B-BF VGA & DVI encoder * &twsi3/sound-codec@30 Sound chip, probably a Marvell 88ce156 * &twsi4/embedded-controller@58 ENE KB3930QF Embedded Controller, also seems to be connected to &ssp4. Might not need a driver -- about the only useful thing it can do is to reboot the machine when tickled via some GPIO lines. Also there seems to be something at &twsi1 address 0x50.
