This uncovered another problem where the pin control "enable" bit was unsettling because the default regmap values were initialized to zeros and driver doesn't set the enable bit at all.
Hi, This series adds USB OTG mode support to the NVIDIA Tegra USB PHY driver, SMB347 charger driver and Nexus 7 tablet. Changelog: 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.
