The commit a4180c3696 ("arm64: zynqmp: Add mode-pin GPIO controller DT
node") added usb phy reset over bootmode pins by default on usb0 only.
zcu100 is using usb0 as peripheral and usb1 as host. Unfortunately reset
line is shared for both usb ulpi phys but usb_rst_b is connected to usb5744
hub which is used only in host mode. Especially this chip requires reset to
operate properly that's why better assign gpio reset to usb1 instead of
usb0.
Without this change usb start crashed when runs.

The node names should be generic and DT schema expects certain pattern:
xilinx/zynqmp-zcu100-revC.dtb: leds: 'vbus-det' does not match any of the regexes: '(^led-[0-9a-f]$|led)', 'pinctrl-[0-9]+'

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.

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.

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.

Most of the legacy "gpio-key,wakeup" boolean property is already
replaced with "wakeup-source". However few occurrences of old property
has popped up again, probably from the remnants in downstream trees.
This patch replaces the legacy properties with the unified
"wakeup-source" property introduced by:
"Input: gpio_keys - switch to using generic device properties"

Somewhere along recent changes to power control of the wl1831, power-on
became very unreliable on the Ultra96, failing like this:
wl1271_sdio: probe of mmc2:0001:1 failed with error -16
wl1271_sdio: probe of mmc2:0001:2 failed with error -16
After playing with some dt parameters and comparing to other users of
this chip, it turned out we need some power-on delay to make things
stable again. In contrast to those other users which define 200 ms,
Ultra96 is already happy with 10 ms.

This patch adds reset-on-timeout to FPD WDT which will trigger an
interrupt to PMU when watchdog expiry happens and PMU takes the
necessary action. If this property is not enabled, reason will not be
known when watchdog expiry happens.
This patch also modifies the default timeout to 60 seconds. Reason is
that if u-boot enables WDT, it will set the timeout to 10 seconds and
this is not enough to boot till Linux and start the WDT application in
Linux. 60 seconds is the maximum safest value to boot till Linux and
start the WDT application.
Users need to change this timeout value to fit their needs.

there is proper reset.

action is taken.
