This series contains patches which are already have been sent in
"usb: dwc2: fixes, enhancements and new features" series.
That patch series was too large, and based on community feedbacks decided to
split that series into small pieces. This is a third part.
In this series we included Active Clock Gating (ACG) and LPM features.
All patches were tested on HAPS-DX7 platform.
Patches from 1-2 related to ACG and logically linked.
Patches from 3-11 related to LPM and logically linked.
Changes after first submission:
usb: dwc2: gadget: Add LPM functionality (LPM):
- "usb: gadget: Allow a non-SuperSpeed gadget to support LPM"
and "usb: gadget: composite: Exclude SS Dev Cap Desc" patches were
removed, because they were already merged to kernel.
- "usb: dwc2: Add core state checking" and "usb: dwc2: Add call_gadget() function call"
patches were added.
- Fixed GLPMCFG initialization. Now hird and besl values also writes into GLPMCFG.
- Replaced shift operator with BIT() macro.
ACG support for dwc2 driver (ACG):
- Previous 4 commits were squashed into 2 ones.
- Added new acg_enable filed in dwc2_hw_params checks ACG support from hardware side.
- Similar acg_enable field in dwc2_core_params used for dynamically disabling/enabling.
