As the old saying goes, "when it rains, it pours down binaries for Nexus devices." That old idiom is proven true once again today, as Google has just uploaded the latest batch of binaries to the Nexus Device download page.
The binaries essentially contain the proprietary hardware drivers that you won't find in AOSP for their specific devices. This go around it's for Android 4.2.2 (build JDQ39) for all of the latest Nexus gadgets: the Nexus 4, Nexus 7 Wi-Fi, Nexus 7 3G, Nexus 10, GSM Galaxy Nexus, and VZW Galaxy Nexus.
More notably, this marks the first time that up-to-date binaries have been available for all current-gen Nexus devices. This is a pretty big deal, in that it also means the Nexus 4 and Nexus 7 3G are finally officially supported by AOSP. Previously, the Nexus 4 was making baby steps into full AOSP support.
Here's a look at the included drivers for each device:
You'll find all the downloads at the Nexus Binaries site.
Additionally, Google pushed the final 4.2.2 AOSP code to individual device repos, thereby completing the 4.2.2 rollout 100%. For example, here are the Nexus 4 and Nexus 7 3G android-4.2.2_r1 git tags:
Update: In response to Artem's question about the lack of GSM binaries on the Nexus 4, JBQ replied confirming that telephony indeed works on the phone, whether because the binaries are actually included or no binaries are needed at all. Moreover, for the first time ever, a device (in fact, both N4 and N7) have 100% of their drivers available:
Telephony will definitely work.
I probably forgot to mention those binaries on the download page. It's
also possible that no proprietary binaries are needed to use telephony
on Nexus 4, in which case it wouldn't get mentioned on the list of
proprietary files. I'm not sure which of the two explanations is the
right one. Either way, telephony works.
For Nexus 4 and for Nexus 7, 100% of the proprietary binaries are
available. That had never been the case for other devices at any point
in the past. That way, you can know that 100% of the functionality on
Nexus 4 and Nexus 7 is supposed to work, without restrictions (other
than those caused by bugs).
