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 .../devicetree/bindings/usb/ci-hdrc-usb2.txt | 4 + drivers/usb/chipidea/Kconfig | 1 + drivers/usb/chipidea/ci_hdrc_tegra.c | 15 +- drivers/usb/phy/phy-tegra-usb.c | 740 ++++++++++-------- drivers/usb/phy/phy-ulpi.c | 48 +- include/linux/usb/ulpi.h | 11 + 6 files changed, 462 insertions(+), 357 deletions(-) -- 2.24.0
