The previously reserved 12th bit in GHWCFG4 now indicates that the
controller supports the Dynamic Power Reduction (Active Clock Gating)
during no traffic scenarios such as L0, idle, resume and suspend
states.

In short this feature specifies, that controller supports Dynamic Power
Reduction
during no traffic scenarios.
Changes in v3:
-added commit for backup and restore of ACG support register
Razmik Karapetyan (4):
usb: dwc2: Define PCGCCTL1 register in hw.h
usb: dwc2: Define Active Clock
Changes in version 2:
Added cover letter for patch set
Done small,but significant changes in interrupt handlers, which will allow
to minimize incomplete ISOC IN/OUT, GOUTNAKEFF interrupt handling.
Razmik Karapetyan (3):
usb: dwc2: Update dwc2_handle_incomplete_isoc_in() function
usb
In 'for' loop skipped masked and non-ISOC EPs. Also breaked 'for' loop
after setting SGOUTNAK in DCTL,when one enabled EP was detected.
This will allow to minimize incomplete ISOC OUT interrupt handling.
