This patch series includes new features such us Active Clock Gating(ACG),
LPM and Hibernation, enhancements and fixes for already existing features.
All this patches were already sent to lkml separately. ACG, LPM and Hibernation
were sent as patch series.
All patches were tested in our lab.
Changes from v2:
Remove stable@xxxxxxxxxxxxxxx from cover letter CC.
"usb: dwc2: Change TxFIFO and RxFIFO flushing flow"
Added default value for greset in dwc2_flush_tx_fifo() and dwc2_flush_rx_fifo() functions.
"usb: dwc2: Bit polling functionality update"
Renamed to "usb: dwc2: Update bit polling functionality"
Changes from v1:
"usb: dwc2: pci: Fix error handling in dwc2_pci_probe" was divided into 4 patches:
"usb: dwc2: pci: Handle error cleanup in probe"
"usb: dwc2: pci: Move devm_kzalloc() before platform_device_add()"
"usb: dwc2: pci: Move usb_phy_generic_register()"
"usb: dwc2: pci: Replace kzalloc() with devm_kzalloc()"
"usb: dwc2: Move polling function to core.c." and "usb: dwc2: Use common polling function."
patches were merged into "usb: dwc2: Bit polling functionality update.".
Also created dwc2_hsotg_wait_bit_clear() function, because in some cases,
we should wait for bit would be cleared not set. Updated all new loops which
came with patches in this series.
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.
usb: dwc2: Add hibernation feature support (Hibernation):
- 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.
- 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.
- 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.
- 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.
ACG support for dwc2 driver (ACG):
- 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
ACG functionality from driver.
usb: dwc2: Add safety check in setting of descriptor chain pointer
Updated description of patch.
usb: dwc2: host: Fix transaction errors in host mode
- Rename patch name from "usb: dwc2: host: Setting TOUTCAL and USBTRDTIM fields in host mode".
- Remove programming of USBTRDTIM bitfiled, because this field available
only in Device mode.
- Added comment with description of TOUTCAL bitfiled in comment.
- In description added platforms for which this patch fixes transactions error.
