Hi, I believe the interrupts and drive-strength properties are Ok. However, letting the platform driver power up the wifi chip does not guarantee proper ordering, does it? I mean, what if the MMC bus was probed before the (non-removable) chip was switched on? Being able to tie that to the mmc controller would be better IMO. I think this was discussed in Olof's "mmc: add support for power-on sequencing through DT" thread. Thanks! ChenYu > > Not sure if this should go in staging or not.
