The first ones shall be re-posted independently: - for the matrix, we need to convert all SoC DT before adding a "panic" statement if the SoC doesn't have a matrix entry. I am pretty confident to have these bits in for 3.15 anyway. - for the pinctrl, we need to cook the idea a little bit more and have Linus' acknowledgement. Thanks a lot for you work.
