f53e102e12 armv8: fsl-layerscape: rework the dwc3 snooping enable code
Instead of looking at all USB (host) devices, just search all DWC3
device tree nodes. This will (1) fix a panic if of_match is zero and (2)
also apply the fixup if the controller is in peripheral mode. Both
happen when the DWC3 USB controller driver is used.

for u-boot:

At the time of this writing the patches were accepted and will be

7f900eabf7 arm: dts: ls1028a: sync the fsl-ls1028a.dtsi with linux
Now that everything is prepared, copy the fsl-ls1028a.dtsi from the
linux kernel v5.14.12.

Notable changes:
 - second watchdog added
 - the number of chip selects of the SPI controller is now correct and
   reflects what the hardware offers
 - the LPUARTs have the correct clock parent
 - USB controllers are enabled by default, which was already the case
   before this sync because all board enabled all the USB controller
   nodes. A linux patch to fix this is pending.
 - the eSDHC controller changes from big-endian to little-endian, but
   that property seems to be not used at all.

d08011d7f9 arm: dts: ls1028a: disable the PCIe controller by default
Disable the PCIe controllers by default, just like in the linux device
tree. But there is one catch, for linux they are enabled in-place by the
bootloader. Obviously, this doesn't work for the bootloader. Thus we
explicitly enable the controllers in the -u-boot.dtsi files.

To make the synchronization of the u-boot device tree with the one from
linux easier, move the I/O window to the one which is specified in the
linux device tree. The actual value shouldn't matter as long as it
mapped to the corresponding memory window of the PCIe controller which
is a 32GiB window at 80_0000_0000h (first controller) or 88_0000_0000h
(second controller).

cde9b147ba scsi: ceva: rename the resource name to match the linux kernel one
The driver will look for a named resource "ecc-addr", but this isn't the
official binding. In fact, the official device tree binding
documentation doesn't mention any resource names at all. But it is safe
to assume that it's the linux ones we have to use if we want to be
compatible with the linux device tree. Thus rename "ecc-addr" to
"sata-ecc" and convert all the users in u-boot.

While at it, also rename "sata-base" to "ahci" although its not used at
all.

This change doesn't affect the SATA controller on the ZynqMP.

compatibles:
  compatible = "fsl,ls1028a-dspi", "fsl,ls1021a-v1.0-dspi";

We can use the fallback "fsl,ls1021a-v1.0-dspi", because the endianness
is determined by the little-endian property and not by the compatible
string itself. Further, we won't need and specific details on the DMA
configuration (which is different on the LS1021A). If it's ever needed,
we can later add the more specific "fsl,ls1028a-dspi" compatible to the

fb5ff321d0 armv8: ls1028a: use the official compatible string for the GPU
There is no "fsl,ls1028a-gpu" compatible string. It is solely for the
proprietary driver which will never be open source. Lately, linux gained
support for the open source etnaviv driver for the GPU (although there
is still support for the DisplayPort PHY missing to get actual graphics
output). Thus, instead of supporting some proprietary driver, switch
over to the open source one, which also have an official device tree
binding.
