The tegra_xusb_port_unregister should be called when usb2_port
and ulpi_port map fails in tegra_xusb_add_usb2_port() or in
tegra_xusb_add_ulpi_port(), fix it.

commit 1db6b0a4246ce708b89f5136571130b9987741d1 upstream.

All PCIe PHYs on sc8180x platform have 2 lanes, so change the number of
lanes to 2.

Merge tag 'soc-drivers-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

2023-02-27T18:04:49+00:00

Pull ARM SoC driver updates from Arnd Bergmann:
 "As usual, there are lots of minor driver changes across SoC platforms
  from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
  These usually add support for additional chip variations in existing
  drivers, but also add features or bugfixes.

  The SCMI firmware subsystem gains a unified raw userspace interface
  through debugfs, which can be used for validation purposes.

  Newly added drivers include:

   - New power management drivers for StarFive JH7110, Allwinner D1 and
     Renesas RZ/V2M

   - A driver for Qualcomm battery and power supply status

   - A SoC device driver for identifying Nuvoton WPCM450 chips

   - A regulator coupler driver for Mediatek MT81xxv"

phy: qcom: phy-qcom-snps-eusb2: Add support for eUSB2 repeater

2023-02-16T13:10:27+00:00

For USB 2.0 compliance, eUSB2 needs a repeater. The PHY needs to
initialize and reset it. So add repeater support

PM8550B contains a eUSB2 repeater used for making the eUSB2 from
SM8550 USB 2.0 compliant. This can be modelled SW-wise as a Phy.
So add a new phy driver for it.

phy: rockchip-typec: Fix unsigned comparison with less than zero

2023-02-16T13:05:25+00:00

The dp and ufp are defined as bool type, the return value type of
function extcon_get_state should be int, so the type of dp and ufp
are modified to int.

phy: rockchip-typec: fix tcphy_get_mode error case

2023-02-14T13:55:28+00:00

The existing logic in tcphy_get_mode() can cause the phy to be
incorrectly configured to USB UFP or DisplayPort mode when
extcon_get_state returns an error code.

extcon_get_state() can return 0, 1, or a negative error code.

It is possible to get into the failing state with an extcon driver
which does not support the extcon connector id specified as the
second argument to extcon_get_state().

tcphy_get_mode()
->extcon_get_state()
-->find_cable_index_by_id()
--->return -EINVAL;
