Hi Maxime,

Here is a patch-set with all the otg / sun8i-usb-host related dts patches I've accumulated.

These are intended for 4.3, and go hand in hand with the outstanding musb-sunxi / phy-sun4i-usb patches, which I expect to be merged as is for 4.3 .

I'm fine with these patches. Do you have a branch somewhere that I can pull (without the one that you wanted me to drop, obviously)?

I've just created a branch with just these patches directly on top of sunxi/for-next for you:

https://github.com/jwrdegoede/linux-sunxi/commits/otg-dts-for-maxime

Please ignore this for now. There have been some changes to the extcon framework, making it more integrated with devicetree, this means I need to add an extcon property to the musb nodes in devicetree:

I'll push a new version of the patches to otg-dts-for-maxime with the extcon property added for you and ping you when it is ready.

While preparing this branch I noticed that the dts for the ippo q8h a33 tablets is not yet merged:

You suggested to use the DT quirks interface instead of creating a separate dts for each board variant, and in the end I agreed, and asked you to merge it renamed to a more generic name without the lcd1024x600 bit in there.

I can make it more generic and resend it myself. Do you want me to squash in the otg changes when I resend it, or shall I keep those separate ?

And about this one: ping ?

Thanks & Regards,

Hans
