[RFC PATCH 1/1] mtd: rawnand: mtk: Re-license MTK NAND driver as Dual MIT/GPL

[Xiaolei Li]

It is allowed to use MTK NAND driver with GPL-2.0 or MIT license.
But now it is only licensed as GPL-2.0.
So re-license it as dual MIT/GPL.

I fear this needs ACKs from all authors and major contributors of the driver
before we can apply such a change.

Thanks,

Yes. MTK wants to solicit ACKs for this change from copyrights holders
here.
I added another driver author Jorge, and let's wait for the response.

You are missing at least Ryder Lee, Rafał Miłecki and Wen Yang in the CC list.
I think it would be good to understand why you want to distribute the driver
under MIT license.

Thanks for your reminding. I will add them in next patch version.

MTK wants to modify and publish this driver with MIT license in
bootloader. So, here we ask for ACKs whether we can re-license it as
dual MIT/GPL.

Relicensing is OK with respect to any Linaro copyright interest deriving
from upstreaming this work.
