Subject[PATCH v3 00/16] NVIDIA Tegra USB2 drivers clean up
Date
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:

v3: - The "Perform general clean up of the code" patch now cleans up couple
more minor crumbs.

- Added more "clean up" patches:

usb: phy: tegra: Disable VBUS regulator on tegra_usb_phy_init failure
usb: phy: tegra: Move utmip_pad_count checking under lock
usb: phy: tegra: Keep CPU interrupts enabled
usb: host: ehci-tegra: Remove unused fields from tegra_ehci_hcd

- I noticed that ULPI's reset is getting erroneously deasserted on
PHY's shutdown, this is fixed in these new patches:

usb: phy: tegra: Assert reset on ULPI close instead of deasserting it
usb: phy: tegra: Use device-tree notion of reset-GPIO's active-state

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 to driver's dependencies

Dmitry Osipenko (16):
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()
