Hi Maxime,
Hi,
This serie aims at fixing an issue we had to carry out of tree patches for for a few years.
The issue is this: a significant number of Allwinner boards don't have an Ethernet connection, while an Ethernet connection is pretty useful for example during development to do some PXE/NFS boot.
However, we needed to have DM_ETH enabled for the boards that use our Ethernet controller drivers that rely on it. It meant having to use the newly introduced DM_ETH support in the usb_ether gadget, but our musb peripheral wasn't converted to the device model, and therefore not usable with it.
The other alternative was to use the old-style usb_ether driver, which worked fine but were disabling the Ethernet controller driver.
Thus, none were good, upstreamable solution.
Fix this properly by adding support for the musb in peripheral mode in the device model. While we're doing so, I also took the occasion to move a number of configuration options to Kconfig, and rework the dependencies between them to ease the selection of related options while trying to avoid as much as possible the combinations that are not valid.
This was tested on a Sinlinx SinA33 that is wired as a peripheral-only mUSB.
Let me know what you think,
Thanks for your effort. I've ack'ed gadget relevant commits, so I think that this series should go through the sunxi tree.
I just applied them to the sunxi/master branch, with both Simon's and your tags added.
(Jagan, if it's not the right branch, please tell me. I'm still getting used to the u-boot way of managing branches).
Thanks! Maxime
