7703efbc99 schemas: Add schema for U-Boot driver model 'phase tags'
U-Boot has some particular challenges with device tree and devices:

- U-Boot has multiple build phases, such as a Secondary Program Loader
  (SPL) phase which typically runs in a pre-SDRAM environment where code
  and data space are limited. In particular, there may not be enough
  space for the full device tree blob. U-Boot uses various automated
  techniques to reduce the size from perhaps 40KB to 3KB. It is not
  always possible to handle these tags entirely at build time, since
  U-Boot proper must have the full device tree, even though we do not
  want it to process all nodes until after relocation.
- Some U-Boot phases needs to run before the clocks are properly set up,
  where the CPU may be running very slowly. Therefore it is important to
  bind only those devices which are actually needed in that phase
- U-Boot uses lazy initialisation for its devices, with 'bind' and
  'probe' being separate steps. Even if a device is bound, it is not
  actually probed until it is used. This is necessary to keep the boot
  time reasonable, e.g. to under a second

The phases of U-Boot in order are: TPL, VPL, SPL, U-Boot (first
pre-relocation, then post-relocation). ALl but the last two are optional.

For the above reasons, U-Boot only includes the full device tree in the
final 'U-Boot proper' build. Even then, before relocation U-Boot only
processes nodes which are marked as being needed.

For this to work, U-Boot's driver model[1] provides a way to mark device
tree nodes as applicable for a particular phase. This works by adding a
tag to the node, e.g.:

   cru: clock-controller@ff760000 {
      bootph-all;
      compatible = "rockchip,rk3399-cru";
      reg = <0x0 0xff760000 0x0 0x1000>;
      rockchip,grf = <&grf>;
      #clock-cells = <1>;
      #reset-cells = <1>;
      ...
   };

Here the "bootph-all" tag indicates that the node must be present in all
phases, since the clock driver is required.

There has been discussion over the years about whether this could be done
in a property instead, e.g.

   options {
      bootph-all = <&cru> <&gpio_a> ...;
      ...
   };

Some problems with this:

- we need to be able to merge several such tags from different .dtsi files
  since many boards have their own specific requirements
- it is hard to find and cross-reference the affected nodes
- it is more error-prone
- it requires significant tool rework in U-Boot, including fdtgrep and
  the build system
- is harder (slower, more code) to process since it involves scanning
  another node/property to find out what to do with a particular node
- we don't want to add phandle arguments to the above since we are
  referring, e.g., to the clock device as a whole, not a paricular clock
- the of-platdata feature[2], which converts device tree to C for even
  more constrained environments, would need to become aware of the
  /options node

There is also the question about whether this needs to be U-Boot-specific,
or whether the tags could be generic. From what I can tell, U-Boot is the
only bootloader which seriously attempts to use a runtime device tree in
all cases. For this version, an attempt is made to name the phases in a
generic manner.

It should also be noted that the approach provided here has stood the test
of time, used in U-Boot for 8 years so far.

So add the schema for this. This will allow a major class of schema
exceptions to be dropped from the U-Boot source tree.

This has been applied upstream[3]

4ee85df9ce cmd: fdt: allow standalone "fdt move"
At the moment every subcommand of "fdt", except "addr" itself, requires
the DT address to be set first. We explicitly check for that before even
comparing against the subcommands' string.
This early bailout also affects the "move" subcommand, even though that
does not require or rely on a previous call to "fdt addr". In fact it
even sets the FDT address to the target of the move command, so is a
perfect beginning for a sequence of fdt commands.

Move the check for a previously set FDT address to after we handle the
"move" command also, so we don't need a dummy call to "fdt addr" first,
before being able to move the devicetree.

This skips one pointless "fdt addr" call in scripts which aim to alter
the control DT, but need to copy it to a safe location first (for
instance to $fdt_addr_r).

6459734619 cmd: fdt: move: Use map_sysmem to convert pointers
The "fdt move" subcommand was using the provided DTB addresses directly,
without trying to "map" them into U-Boot's address space. This happened
to work since on the vast majority of "real" platforms there is a simple
1:1 mapping of VA to PAs, so either value works fine.

However this is not true on the sandbox, so the "fdt move" command fails
there miserably:
=> fdt addr $fdtcontroladdr
=> cp.l $fdtcontroladdr $fdt_addr_r 40  # simple memcpy works
=> fdt move $fdtcontroladdr $fdt_addr_r
Segmentation fault

Use the proper "map_sysmem" call to convert PAs to VAs, to make this
more robust in general and to enable operation in the sandbox.

be more helpful to show the actual image name. This is tricky because
Image is a parent class of Entry_section, so there is no distinction
between an image and a section.

Update it to show the image name.

a5e490f14e socfpga: fix the serial console on DE1-SoC
Previously, the TX LED would flash but nothing would appear on the
serial port, and the board would appear dead with a build of the
socfpga_cyclone5_defconfig. I have verified that adding the frequency to
the uart will fix the serial console on my board.

This contains various fixes and small features. I've included a reset patch as
 well since it was in the same series as a clock patch.

c40251c120 cmd: clk: probe the clock before dump them
The clock UCLASS need to be probed to allow availability of the
private data (struct clk *), get in show_clks() with dev_get_clk_ptr()
before use them.

Without this patch the clock dump can cause crash because all the
private data are not available before calling the API clk_get_rate().

It is the case for the SCMI clocks, priv->channel is needed for
scmi_clk_get_rate() and it is initialized only in scmi_clk_probe().
This issue causes a crash for "clk dump" command on STM32MP135F-DK board
for SCMI clock not yet probed.

[backport from linux commit 2626cf67f20b28446dfc3a5b9493dd535cdb747b]

e02bf587d3 clk: imx: rename video_pll1 to video_pll
[backport from linux commit bedcf9d1dcf88ed38731f0ac9620e5a421e1e9d6]

Unlike audio_pll1 and audio_pll2, there is no video_pll2. Further, the
name used in the RM is video_pll. So, let's rename "video_pll1" to
"video_pll" to be consistent with the RM and avoid misunderstandings.

No functional changes intended.

d0cc6a6ca1 clk: imx8mn: rename vpu_pll to m7_alt_pll
[backport from linux commit a429c60baefd95ab43a2ce7f25d5b2d7a2e431df]

The IMX8MN platform does not have any video processing unit (VPU), and
indeed in the reference manual (document IMX8MNRM Rev 2, 07/2022) there
is no occurrence of its pll. From an analysis of the code and the RM
itself, I think vpu pll is used instead of m7 alternate pll, probably
for copy and paste of code taken from modules of similar architectures.
