Hi all,
The primary objective of this series is to reinstate basic USB support for the cm_fx6 module which was effectively removed by Commit 5248930ebf48 ("dm: imx: cm_fx6: Enable more driver model support").
This is achieved by synchronizing the devicetree with Linux (patch 1) and by enabling device model support for keyboards (patch 2).
There are still some USB limitations/regressions not fixed by this series:
The OTG port doesn't work (the controller is enumerated but it looks like it is not switched to host mode).
I have to use a hub to connect any of my keyboards (USB 1.1 devices?) which is odd because there is already an internal hub.
Patches 3 & 4 remove some dead init code in the board file that is no longer used/required now that device model support for the related devices is enabled.
The USB related init code in the board file is still required (removal of any part of it renders USB completely unusable, the controllers are not enumerated) -- is this expected?
Cheers, Christopher
