ef74a97f0d phy: qcom-qmp-ufs: fix memleak on probe deferral 
Switch to using the device-managed of_iomap helper to avoid leaking
memory on probe deferral and driver unbind.

Note that this helper checks for already reserved regions and may fail
if there are multiple devices claiming the same memory.

af96579dc3 phy: ti: gmii-sel: Add support for CPSW5G GMII SEL in J7200 
Each of the CPSW5G ports in J7200 support additional modes like QSGMII.
Add a new compatible for J7200 to support the additional modes.

In TI's J7200, each of the CPSW5G ethernet interfaces can act as a
QSGMII or QSGMII-SUB port. The QSGMII interface is responsible for
performing auto-negotiation between the MAC and the PHY while the rest of
the interfaces are designated as QSGMII-SUB interfaces, indicating that
they will not be taking part in the auto-negotiation process.

To indicate the interface which will serve as the main QSGMII interface,
add a property "ti,qsgmii-main-ports", whose value indicates the
port number of the interface which shall serve as the main QSGMII
interface. The rest of the interfaces are then assigned QSGMII-SUB mode by
default. The property "ti,qsgmii-main-ports" is used to configure the
CTRLMMR_ENETx_CTRL register.

Depending on the device, it is possible for more than one QSGMII main port
to exist. Thus, the property "ti,qsgmii-main-ports" is defined as an array
of values in order to reuse the property for other devices.

The lane reset is defined in the "lane" node so there's no need to keep
adding a redundant lane-number suffix to the reset name.

Update driver to support the new binding where the "lane" reset name has

533e13305c phy: tegra: xusb: Only warn once about reset problems in .remove() 
The single difference between returning 0 and returning an error code in
a platform remove callback is that in the latter case the platform core
emits a warning about the error being ignored.

If reset_control_assert() fails there is already a warning, so suppress
the more generic (and less helpful) by returning 0 in
tegra_xusb_padctl_remove().

This is a preparation for making platform remove callbacks return void.
