Expecting a lot of devices and differences? I would assume all known h/w 
is well known and any differences are known by now. Perhaps even just 
the fallback is sufficient?

From 3 to 5, maybe more. Hard to trach different variations. Having no full schematic does not help either.

"Motorola" is the vendor, "mot" is the board name. Same name you have recently seen in the CPCAP schema patches I have sent.

[PATCH v2 4/5] ASoC: tegra: Support WM8962 by machine driver

[Svyatoslav Ryhel]

From: Jonas Schwöbel <jonasschwoebel@yahoo.de>

Add Wolfson Microelectronics WM8962 codec support to the Tegra ASoC
machine driver. The WM8962 codec is found on devices like Microsoft
Surface RT and Microsoft Surface 2 Windows RT based tablets.
