* [PATCH v3 00/14] Add mt76x0 driver @ 2018-07-31 12:40 ` Stanislaw Gruszka 0 siblings, 0 replies; 55+ messages in thread From: Stanislaw Gruszka @ 2018-07-31 12:40 UTC (permalink / raw) To: linux-wireless Cc: Lorenzo Bianconi, Felix Fietkau, Hans Ulli Kroll, Jakub Kicinski, Michal Schmidt, linux-mediatek, Stanislaw Gruszka Add mt76x0 driver for MT7610U based USB dongles. Currently driver support only STA mode. mt76x0 is based on Jakub's mt7601u driver already included in the kernel. I would like the driver be integrated as part of mt76 (instead of separate driver in mediatek dir like mt7601u) to utilize mt76 code for adding support for MT76x0 PCIe devices in further development. To do not collide with current mt76x2u work from Lorenzo, I did not remove some code duplication. This will be done in the future as well as add support for MT76x0 PCIe devices (i.e. MT7630E). My and Lorenzo integration efforts can be traced here: https://github.com/sgruszka/wireless-drivers-next/commits/mt76x0-draft-v2 mt7610u.bin file will be posted to linux-firmware tree as Sean Wang at Mediatek gave us permission to do so.

I think we can integrate mt7601u in mt76 as soon as mt76x0 is merged since the code path is pretty similar. Jakub what do you think?

This driver if for MT7610 chip. There are lot of similarities between the drivers, but there are bunch of differences too. And in the future development of mt76x0, due to integration into mt76 and mt76x2u and adding support for PCIe chips, the differences against mt7601u will be much be bigger. > Also I noticed that mt76 is missing an entry in MAINTAINERS file? Could > someone send a separate patch to add that, please? The question is if Felix would like to be the maintainer? Otherwise who would want to do this job? I think the best option would be to get some commitment from Mediatek if that possible, maybe Sean Wang could aggree to be the maintainer ? :-) Thanks Stanislaw ^ permalink raw reply [flat|nested] 55+ messages in thread

This driver if for MT7610 chip. There are lot of similarities between the drivers, but there are bunch of differences too. And in the future development of mt76x0, due to integration into mt76 and mt76x2u and adding support for PCIe chips, the differences against mt7601u will be much be bigger. > Also I noticed that mt76 is missing an entry in MAINTAINERS file?

I think the best option would be to get some commitment from Mediatek if that possible, maybe Sean Wang could aggree to be the maintainer ? :-) Thanks Stanislaw ^ permalink raw reply [flat|nested] 55+ messages in thread

Another option is to have one maintainer and one or more reviewers: R: Designated reviewer: FullName <address@domain> These reviewers should be CCed on patches. And even better if Mediatek could actively join the development and review. -- Kalle Valo ^ permalink raw reply [flat|nested] 55+ messages in thread
