Hi,
the series is syncing the latest dt changes based on board status and the
latest DT schema.
The patches are based on
https://lore.kernel.org/all/20230321070619.29440-1-parth.gajjar@amd.com/
I have applied patches which were reviewed already to have smaller series.
Patches can be found https://github.com/Xilinx/linux-xlnx/tree/zynqmp/dt
Or they are in Linux-next already.
v1 is at
https://lore.kernel.org/r/7d034b9e-e4e6-5d72-8b37-78e25918aa59@amd.com.
Thanks,
Michal

TI DP83867 is using strapping based on MIO pins. Tristate setup can
influence 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. Phy reset is done via gpio.

Changes in v2:
- fix typo in commit message
Checkpatch is reporting issue
warning: DT compatible string "ethernet-phy-id2000.a231" appears un-documented
but it should be fully aligned with
Documentation/devicetree/bindings/net/ethernet-phy.yaml
c&p more details from v1 version:
Phy has some pins which is using for strapping for phy address after phy
reset or power on. Pretty much it is resistor array which based on
datasheet is decoded to certain phy address.
And because some phy pins are also used as data pin for RGMII they are
connected via MIO pins on a silicon. That's why IO block output setting
really matter here because it changes resistor array and it moves phy
address.
That's why there is a need to do proper IO pin setup and after it call phy
reset to get it to address which was decided by PCB designer.

As per design, all input/rx pins should have fast slew rate and 12mA
drive strength. Rest all pins should be slow slew rate and 4mA drive
strength. Fix usb nodes as per this and remove setting of slow slew rate
for all the usb group pins.

(no changes since v1)
c&p more explanation from v1 version.
In design tools all inputs pins are setup like described by default. That's
why it could suggest that there is no need to describe default
configuration in DT. But all MIOs can be used as GPIOs where pinctrl can
change their default values to something else. That's why setting up
default values is to be safe even for input pins. I don't know HW details
to that extend but that values can also change input behavior that's why
having default is not a bad idea.

From: Amit Kumar Mahapatra <amit.kumar-mahapatra@xilinx.com>
All ZynqMP boards are setting up tx-buswidth 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.
Using all 4 lines will increase the tx data transfer rate, as now the
tx data will be transferred on four lines instead on single line.

Changes in v2:
- Update commit message to remove Linux part - reported by Laurent
Linux kernel throws "cacheinfo: Unable to detect cache hierarchy for
CPU 0" warning when booting on zu+ Soc. To fix it add the L2 cache
node and let each CPU point to it.

Based on dt-binding "This property should present when there is more than a
single SPI" that's also case that's why explicitly specify interrupt
affinity to avoid incorrect usage.

Changes in v2:
- Update commit message to remove OS content - reported by Laurent
This avoids the following error upon linux boot:
armv8-pmu pmu: hw perfevents: no interrupt-affinity property,

Using fixed partitions is recommended way how to describe QSPI. Also add
label for qspi flash memory to be able to reference it in future.
