Subject: [PATCH v2 00/10] NVIDIA Tegra USB2 drivers clean up

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

Dmitry Osipenko (10):
  dt-binding: usb: ci-hdrc-usb2: Document NVIDIA Tegra support
  usb: phy: tegra: Hook up init/shutdown callbacks
  usb: phy: tegra: Perform general clean up of the code
  usb: phy: tegra: Use relaxed versions of readl/writel
  usb: phy: tegra: Use generic stub for a missing VBUS regulator
  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
  usb: chipidea: tegra: Stop managing PHY's power
  usb: chipidea: tegra: Add USB_TEGRA_PHY module to driver's
    dependencies
