efa1ddea07 arm64: zynqmp: Record compatible string for kv260 rev2
PCB rev2 compare to rev1 has some changes in PL side (IAS sensor AR1335
autofocus feature). PS side is completely unchanged.

dd0ebfe8a4 arm64: zynqmp: Remove comment about gem spec in kv260
The latest SOM specification doesn't enforce certain MIO lines allocated
for ethernet or ethernet controller itself. That's why remove comment about
it which is likely there from early version of specification.
Also removed the same comment from pinctrl node. It is clear that it has to
be defined for different carrier cards.

8489b6d2e3 arm64: zynqmp: Fill model name for SOM CCs
When U-Boot do DTB reselection origin model for SOM is used and from log it
is not visible if DTB was switched or not. That's why add model directly to
CC (carrier card) to show new model if reselection was successful.

b8745e7eb4 arm64: zynqmp: Fix usb node drive strength and slew rate
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 gorup pins.

8b82a3a7fe arm64: zynqmp: Enable DP driver for SOMs
The main reason is to send pmufw cfg overlay from U-Boot to PMUFW to enable
access to DP. Overlay is sent when cls command is called and for that IP
has to be enabled in carrier cards.
And IP needs to be also enabled in SOM dt because with DTB reselection new
DT is not parsed in pre reloc U-Boot instance. It is called from board_f
via embedded_dtb_select(). That's why bind function is not able to allocate
memory and it ends up with error:
"Video device 'display@fd4a0000' cannot allocate frame buffer memory
-ensure the device is set up before relocation"

To avoid this situation DP is placed also to SOM where bind function is
called and frame buffer memory is allocated and just reused after DTB
reselection. Result is the same. There could be a problem in Linux with
different DP configurations but that's need to be solved there because
console should be on from u-boot already.

ff79448294 arm64: zynqmp: Switch to ethernet-phy-id in kv260
Use ethernet-phy-id compatible string to properly describe phy reset on
kv260 boards. Previous description wasn't correct because reset was done
for mdio bus to operate and it was in this case used for different purpose
which was eth phy reset. With ethernet-phy-id phy reset happens only for
the phy via phy framework.

a3efa53c01 arm64: zynqmp: Use assigned-clock-rates for setting up clock in SOM
With limited low level configuration done via psu-init only IPs connected
on SOM are initialized and configured. All IPs connected to carrier card
are not initialized. There is a need to do proper reset, pin configuration
and also clock setting.
The patch targets the last part which is setting up proper clock for USBs
and SDs.
Also setup proper bus width for SD cards.

a502a87bc0 arm64: zynqmp: Add description for SOM/Kria boards
The patch contains several DT files for SOM platform.
Carrier card is sck-kv (KV260) revA/B. SMK-K26 is description for starter
kit which doesn't have EMMC populated. And SM-K26 is full som with EMMC.

Files are divided in this way to make sure that SOM can be plugged to
different carrier card and all peripherals on SOM (or defined by a spec) can
be used by U-Boot. Full DT for SOM+CC can be merged together as overlays.
