Maybe building as a module is more appropriate here as I am not sure
that anyone else will want this built-in and it is not critical to
booting AFAIK.

Cheers

Since the DesignWare core framework doesn't yet have support for making this
as a module, I added it as a built-in driver. I'll switch it to a module
once support is available.

Ah I see. We often get reports/patches if a driver has a removal
function but is defined in the Kconfig to only support being built-in.

Does the designware core just need to export some symbols to support it
being a module? If so it maybe worth adding these as part of the series
to see if it is acceptable, otherwise it might not get done and there is
no point us supporting it as a module.

Cheers
