On the related note of corporations and FOSS, there was a news today from bootlin (ex free-electrons), a french software company well known for being the (co-)maintainers of some parts of the linux kernel (Atmel, Allwinner, Marvell, RTC&NAND subsystems...) : https://bootlin.com/blog/kickstarter...sfully-funded/

I don't recall having seen before a crowdfunding for developing drivers (except maybe bug-bounties), but I may have missed it.

Anyway, it was a success, and was backed by quite a few of the companies that will benefit from the support of the Allwinner VPU on the board they sell: OrangePi, Libre Computer, neutis.io, FriendlyArm, Pine64, Olimex.

Not exactly the same kind of contribution that what juiceme was showing above, and should be done by allwinner directly, but it is good to see that a lot of people and companies are ready to contribute in a way or another.
