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 fourth and last part.
In this series we included only patches related with hibernation.
All patches were tested on HAPS-DX7 platform.
Changes after first submission:
usb: dwc2: Add hibernation feature support (Hibernation):
usb: dwc2: gadget: Fix dwc2_restore_device_registers
- Added WA in dwc2_restore_device_registers() function for enabled
EPx's IN
in DDMA mode for not to get BNA Interrupt asserted on hibernation
exit.
usb: dwc2: Add helper functions for restore routine
- Added argument is_host to determine if core is in host mode or not
and
changed some udelay values in dwc2_hib_restore_common() function.
- Added is_host function parameter to determine being in host mode,
checking
host mode to set pcgcctl properly and changed hard coded numbers to
defined values also changed the logic of loading restore values for
[31:14] bits in dwc2_restore_essential_regs() function.
usb: dwc2: Add dwc2_handle_gpwrdn_intr() handler
- Fixed a minor bug: added checks for determine hibernation exiting
flows
in dwc2_handle_gpwrdn_intr() function. Also changed the way of
clearing
all interrupts.
usb: dwc2: Add host/device hibernation functions
- dwc2_gadget_enter_hibernation() fixed some minor bugs, phy clock now
remains not stopped. Added unmasking of GPWRDN_STS_CHGINT_MSK device
mode interrupts in GPWRDN.
- dwc2_host_enter_hibernation() added a udelay after writing in gpwrdn
register.
