phy: tegra: xusb: Add Tegra234 support

2023-01-12T17:27:06Z

Add support for the XUSB pad controller found on Tegra234 SoCs. It is mostly similar to the same IP found on Tegra194, because most of the Tegra234 XUSB PADCTL registers definition and programming sequence are the same as Tegra194, Tegra234 XUSB PADCTL can share the same driver with Tegra186 and Tegra194 XUSB PADCTL. Introduce a new feature, USB2 HW tracking, for Tegra234. The feature is to enable HW periodical PAD tracking which measure and capture the electric parameters of USB2.0 PAD.

phy: tegra: xusb: Disable trk clk when not in use

2023-01-12T17:27:06Z

Pad tracking is a one-time calibration for Tegra186 and Tegra194. Clk should be disabled after calibration. Disable clk after calibration. While at it add 100us delay for HW recording the calibration value.

phy: tegra: p2u: Set ENABLE_L2_EXIT_RATE_CHANGE in calibration

2022-10-28T12:13:12Z

Set ENABLE_L2_EXIT_RATE_CHANGE register bit to request UPHY PLL rate change to Gen1 during initialization. This helps in the below surprise link down cases, - Surprise link down happens at Gen3/Gen4 link speed. - Surprise link down happens and external REFCLK is cut off, which causes UPHY PLL rate to deviate to an invalid rate.

phy: tegra: xusb: Fix crash during pad power on/down

2022-10-17T05:37:37Z

Commit a88520bfc0ec ("usb: gadget: tegra: Reduce pad power") added calls to tegra_phy_xusb_utmi_pad_power_on/down in the Tegra XUDC driver to control the pad power. This change is causing a kernel panic when powering down the pads on entering suspend with the Jetson TX2 platform. The panic occurs because the 'xudc->curr_utmi_phy' is not configured on this platform and we do not check to see if the pointer is valid before attempting to deference the pointer. Fix this by checking to see if the 'phy' pointer passed to tegra_phy_xusb_utmi_pad_power_on/down is valid.

Merge tag 'usb-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

2022-10-07T23:48:26Z

Pull USB / Thunderbolt updates from Greg KH: "Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1. Nothing major in here, lots of little things with new devices supported and updates for a few drivers. Highlights include: - thunderbolt/USB4 devices supported a bit better than before, and some new ids to enable new hardware devices - USB gadget uvc updates for newer video formats and better v4l integration (the v4l portions were acked by those maintainers) - typec updates for tiny issues and more typec drivers for new chips. - xhci tiny updates for minor issues - big usb-serial ftdi_sio driver update to handle new devices better - lots of tiny dwc3 fixes and updates for the IP block that is showing up everywhere these days - dts updates for new devices being supported - other tiny janitorial and cleanups fixes for lots of different USB drivers. Full details are in the shortlog.

phy: tegra: xusb: Use dev_err_probe() to simplify code

2022-09-24T07:04:56Z

In the probe path, dev_err() can be replaced with dev_err_probe() which will check if error code is -EPROBE_DEFER and prints the error name. It also sets the defer probe reason which can be checked later through debugfs.
