Hello,
This patch series brings the NVIDIA Tegra USB2 PHY driver into a better shape by refactoring code to match upstream standards, the ChipIdea/Tegra UDC driver also gets a minor update. Please review and apply, thanks in advance!
Changelog:
v2: - The "usb: phy: tegra: Hook up init/shutdown callbacks" patch was updated and now it does a better job in regards to checking whether PHY is initialized before it is started to be used and whether there is a double init/shutdown. This allows to factor out the ChipIdea's driver change into a separate patch, which was requested by Peter Chen in a review comment to v1. In a result there is this new patch:
usb: chipidea: tegra: Stop managing PHY's power
- Added few more new patches:
usb: phy: tegra: Use generic stub for a missing VBUS regulator
I noticed that VBUS regulator usage could be cleaned up a tad as well.
usb: ulpi: Add resource-managed variant of otg_ulpi_create() usb: phy: tegra: Use devm_otg_ulpi_create() usb: phy: tegra: Use u32 for hardware register variables
These patches are made in response to review comments that were made by Thierry Reding to v1.
I also noticed that phy_tegra_usb isn't getting auto-loaded while it should be. This is fixed in this new patch:
usb: chipidea: tegra: Add USB_TEGRA_PHY module to driver's dependencies
