This series adds USB OTG mode support to the NVIDIA Tegra USB PHY driver
and Nexus 7 tablet.
Changelog:
v7: - v6 partially missed 5.15 kernel, only the power/supply patches has
been merged. Re-sending the remaining patches for 5.16. The usb/phy
patch needs ack from the subsystem maintainer.
v6: - Added r-b from Rob Herring to the OTG properties DT binding patch.
- Corrected "smb347-charger: generic regmap caching" patch, it now
sets the .num_reg_defaults_raw, initializing cache properly.
- Added new patch "smb347-charger: Add missing pin control activation",
which prevents never-enabled charging on Nexus 7.
- The "otg-fsm: Fix hrtimer list corruption" patch of v5 was already
applied to next, so it's not included anymore.
v5: - Replaced "Remove caching of charger state" patch with "Utilize
generic regmap caching" after Sebastian's notice about disabled
regmap caching.
v4: - Added r-b from Rob Herring.
- Added unevaluatedProperties into SMB binding for VBUS regulator,
which was Requested by Rob Herring.
- Added cell to nvidia,pmc phandle instead of explicit h/w ID
property. Requested by Rob Herring.
- Added stack trace to commit message and ack from Peter Chen to
OTG FSM patch.
v3: - Further improved interrupt handling in the PHY driver by removing
assumption that interrupt is enabled by the CI driver at the time
of set_wakeup() invocation, which makes this function a bit more
universal.
v2: - The PHY's interrupt is now enabled from PHY's set_wakeup() callback.
It prevents getting a spurious interrupt during the CI driver probe
time.
