[PATCH v3 0/5] usb: musb_dsps: support for suspend and resume

[Daniel Mack <zonque@gmail.com>]

v3 of my musb_dsps suspend patches.

With these patches applied, I can successfully bring an AM335x board
to suspend with a USB media connected, and access it again after
resume.

This works for both PIO mode and CPPI41 enabled configurations,
together with Sebasitian's and my cppi41 patches recently posted.

Felipe, this work was rebased and now applies cleanly on top of
your current 'next' branch. IOW, on top of "usb: musb: cppi41: allow
to defer probing if DMA isn't yet available".


Thanks,
Daniel

v2 -> v3
	* dropped "usb: musb: move port reset to worker" which is
	  not crucial for this series.
