But first @Bjorn and @Andy or @David can you please look and review v4 "pinctrl: msm: fix gpio-hog related boot issues" <https://patchwork.kernel.org/patch/10339129/> Thanks. > > The MR24 craze is mostly over by now.

Yes, I'm aware of that some of them where put to good use in the Personal Telco Projec (501(c)(3) non-profit organization in Portland, Oregon): <https://personaltelco.net/wiki/PersonalTelco> And they have been somewhat vocal about it too: <https://groups.google.com/forum/#!msg/ptp-general/RZ-VjKFonVo/cQgnGn2wAgAJ> "The MR24 is a dual-band 802.11n 3x3 MIMO access point with a single ethernet port. They are "last-gen" devices, and are starting to show up on ebay at reasonable prices as Meraki's deep-pocket cloud-management enterprise users are beginning to "upgrade" to 802.11ac gear. Note that 802.11n in this case means a fully-open-source driver (ath9k). 802.11ac drivers involve firmware blobs across the board. You don't get super-wide 5GHz channels, but you get freedom. " ;) By the way, it gets even weirder. In the past (and to this day) Meraki has given away their current crop of enterprise APs via their "Free AP for IT Professionals" <https://meraki.cisco.com/tc/freeap> program. Of course, the main idea probably was to get them all "hooked/sold" on their cloud-management firmware. Because of course that "Free AP" is intended to be only good for the lifespan of included the 3-year license. However, "IT Professionals" do have their own mind and that's why there is some continued interest in making alternative firmwares for these devices.
