Merge tag 'musb-for-v6.2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into soc/dt

Devicetree related musb changes for omap3 for v6.2

Recent musb driver regressions eposed two issues for musb legacy
probing. The changes to use device_set_of_node_from_dev() confuse
the legacy interconnect code. And we now have to manually populate
the musb core irq resources.

The musb driver has a fix for these, but it's not a good long term
solution. To fix the issue properly, let's just update musb to
probe with ti-sysc interconnect driver with proper devicetree data.
This allows dropping most of the musb driver workaround later on.
And with these changes we have the omap2430 musb glue layer behaving
the same way for all the SoCs using it.

We need to patch the ti-sysc driver quirks, and add devicetree
data to make things work. And we want to drop the legacy data too
to avoid pointless warnings.

As we have a musb driver workaround, these changes are not needed as
fixes and can wait for the merge window.
