PATCH v2 1/1 ARM: mxs: Add initial support for Bluegiga APX4 Development Kit

Quoted 7 lines · Sascha Hauer
Quoted 3 lines · Lauri Hintsala

Hello Sascha,

Is this board support patch OK for releasing?

Yes, it's ok. I can't garantuee that it makes it in this merge window though.

Could I help you somehow to get patches this merge window? I would like to have our board to be support by next kernel.
