Dear Vaibhav, dear Johan, dear Alex, dear Greg,

I have seen that the greybus arche driver has been under heavy development in 2016 and 2017 with some further clean-up in 2019.

However, so far, the config GREYBUS_ARCHE for this driver still depends on the out-of-tree config USB_HSIC_USB3613, with a proper exception made for compile testing (with COMPILE_TEST).

Will this USB_HSIC_USB3613 config and driver still be added in the mainline kernel in the near future, so that the config dependencies are consistent in mainline?

Do you have this hardware? If so, we can add the driver, but given that I did not think the chip ever actually shipped, it didn't make much sense.

Or, are the further out-of-tree additions still maintained for the current kernel and will stay out of tree? Is this arche driver not needed anymore and can be dropped?

Do you want to drop it as it is causing problems for you? It's a good example driver for those wanting to create a greybus host controller driver so it's nice to have in the tree, unless you have a different one that should be merged instead?

thanks,

greg k-h
