With ethernet-phy-id driver ETH phy reset can be properly handle that's why
describe it in DT.

13622c7a9d arm64: zynqmp: Describe TI phy as ethernet-phy-id
TI DP83867 is using strapping based on MIO pins. Tristate setup can influce
PHY address. That's why switch description with ethernet-phy-id compatible
string which enable calling reset. PHY itself setups phy address after
power up or reset. Reset description will be added in separate commit.

6e38e2ea79 arm64: zynqmp: Set qspi tx-buswidth to 4
In all the ZynqMP boards dts files tx-buswidth is by default set to 1. Due
to this the framework only issues 1-1-1 write commands to the GQSPI driver.
But the GQSPI controller is capable of handling 1-4-4 write commands, so
updated the tx-buswidth to 4 in ZynqMP boards dts files. This would enable
the spi-nor framework to issue 1-4-4 write commands instead of 1-1-1. This
will increase the tx data transfer rate, as now the tx data will be
transferred on four lines instead on single line.

15ca9ebb07 arm64: zynqmp: Move USB3 PHY properties from DWC3 node to USB node
Move the PHY properties from DWC3 node to USB node in ZynqMP DTs as here
the USB3 PHY used is PSGTR, which is connected to Xilinx USB core. This
PHY initialization should be handled from Xilinx USB core as the
prerequisite register configurations are done here only.

52caf2c12b arm64: zynqmp: Remove gpio from aliases list
It is not recommended to have aliases for gpio. In past it was used in
Linux for assigning numbers via sysfs which is deprecated and libgpiod
should be used instead.
In U-Boot this number is used for seq number but gpio offset are not
counted from this number. That's why having these aliases only for seq
number is not needed. As is done in Linux it is the best to use full gpio
name instead of sequence number which depends on sequence in binding.

Mainline kernel has psgtr driver that's why it is good to add description
to DT files. Some boards are just missing description for USB3 and sata.
zc1751-dc1 and p-a2197 are also missing clock descriptions for input
clocks.

486f25c727 arm64: zynqmp: Add 'i2c-mux-idle-disconnect' property
I2C muxes that have the slave devices with same address are
falling into the below problem.

VCK190 system controller (SC) - zynqmp-e-a2197-00-revA.dts
I2C1 (0xff030000) -> Mux1 (@0x74) -> Channel 3 -> 0x50
I2C1 (0xff030000) -> Mux2 (@0x75) -> Channel 0 -> 0x50

1. SC accesses I2C1 - Mux1 (0x74) - Channel 3 and then
2. SC accesses I2C1 - Mux2 (0x75) - Channel 0.

Now it results in 2 slave devices with same address (0x50)
on the I2C bus, making the communication un-reliable.

When ' i2c-mux-idle-disconnect' is in DT, after '1', the Mux
channel output is disconnected, making none of the channels
available to the I2C1. So, there is no question of having the
same addressed slave (0x50) present on the bus when we are doing '2'.

Same pattern is seen in below two boards also.

ZCU208 - zynqmp-zcu208-revA.dts
ZCU216 - zynqmp-zcu216-revA.dts

12ffe75819 arm64: zynqmp: Add 'no-1-8-v' property for ZynqMP Boards
Modify dts files to add 'no-1-8-v' property for all the ZynqMP boards.
User can remove this property to enable the UHS mode. This is to keep
the same speed (HS) modes across all the stages of the Linux Boot. Due
to power cycling limitation of some of the ZynqMP boards, some SD cards
don't get power cycled and are failing in Linux.
