Binding schemas which define child node properties such as memory
controllers with timing properties need a separate schema which can be
referenced from child device schemas. This is necessary for
unevaluatedProperties checks to work properly.

Move the ingenic,nemc child properties to its own file and reference
from ingenic,nand.yaml which describes a child NAND controller.

SPI peripheral device bindings need to reference spi-peripheral-props.yaml
in order to use various SPI controller specific properties. Otherwise,
the unevaluatedProperties check will reject any controller specific
properties.

The 'unevaluatedProperties' schema checks is not fully working and doesn't
catch some cases where there's a $ref to another schema. A fix is pending,
but results in new warnings in examples.

The Apple PCIe host schema is missing 'power-domains' in the schema.
The example has 3 power domains. However, this is wrong too as actual
dts files have a single power domain and Sven confirmed 1 is correct.

All existing vendor DTSes are using "cpm_slcr" reg followed by "cfg" reg.

This order is also suggested by node name which is pcie@fca10000 which
suggests that cpm_slcr register should be the first.

Driver itself is using devm_platform_ioremap_resource_byname() for both
names that's why there is no functional change even on description which
are using current order.

But still prefer to change order to cover currently used description.

Pull tracing updates from Steven Rostedt:
 "The majority of the changes are for fixes and clean ups.

  Notable changes:

   - Rework trace event triggers code to be easier to interact with.

   - Support for embedding bootconfig with the kernel (as suppose to
     having it embedded in initram). This is useful for embedded boards
     without initram disks.

   - Speed up boot by parallelizing the creation of tracefs files.

   - Allow absolute ring buffer timestamps handle timestamps that use
     more than 59 bits.

   - Added new tracing clock "TAI" (International Atomic Time)

   - Have weak functions show up in available_filter_function list as:
     __ftrace_invalid_address___<invalid-offset> instead of using the
     name of the function before it"

The symbol hwa742_update_window_async() is exported, but there is no
prototype defined for it. That's why gcc complains:

drivers-video-fbdev-omap-hwa742.c:warning:no-previous-prototype-for-hwa742_update_window_async

Add the prototype, but I wonder if we couldn't drop exporting the symbol
instead. Since omapfb_update_window_async() is exported the same way,
are there any users outside of the tree?

When building the kernel for arm with the "-mabi=apcs-gnu" option, gcc
will force alignment of all structures and unions to a word boundary
(see also STRUCTURE_SIZE_BOUNDARY and the "-mstructure-size-boundary=XX"
option if you're a gcc person), even when the members of said structures
do not want or need said alignment.

This completely messes up the structure alignment of 'struct edid' on
those targets, because even though all the embedded structures are
marked with "__attribute__((packed))", the unions that contain them are
not.

This was exposed by commit f1e4c916 ("drm/edid: add EDID block count
and size helpers"), but the bug is pre-existing.  That commit just made
the structure layout problem cause a build failure due to the addition
of the

        BUILD_BUG_ON(sizeof(*edid) != EDID_LENGTH);

sanity check in drivers/gpu/drm/drm_edid.c:edid_block_data().

This legacy union alignment should probably not be used in the first
place, but we can fix the layout by adding the packed attribute to the
union entries even when each member is already packed and it shouldn't
matter in a sane build environment.

You can see this issue with a trivial test program:

  union {
	struct {
		char c[5];
	};
	struct {
		char d;
		unsigned e;
	} __attribute__((packed));
  } a = { "1234" };

where building this with a normal "gcc -S" will result in the expected
5-byte size of said union:

	.type	a, @object
	.size	a, 5

but with an ARM compiler and the old ABI:

    arm-linux-gnu-gcc -mabi=apcs-gnu -mfloat-abi=soft -S t.c

you get

	.type	a, %object
	.size	a, 8

instead, because even though each member of the union is packed, the
union itself still gets aligned.

This was reported by Sudip for the spear3xx_defconfig target.

Commit b3c9a924 ("fbdev: vesafb: Cleanup fb_info in .fb_destroy rather
than .remove") fixed a use-after-free error due the vesafb driver freeing
the fb_info in the .remove handler instead of doing it in .fb_destroy.

This can happen if the .fb_destroy callback is executed after the .remove
callback, since the former tries to access a pointer freed by the latter.

But that change didn't take into account that another possible scenario is
that .fb_destroy is called before the .remove callback. For example, if no
process has the fbdev chardev opened by the time the driver is removed.

If that's the case, fb_info will be freed when unregister_framebuffer() is
called, making the fb_info pointer accessed in vesafb_remove() after that
to no longer be valid.

To prevent that, move the expression containing the info->par to happen
before the unregister_framebuffer() function call.

This reverts commit 8bdc2a19.

It got merged a bit prematurely and shortly after the kernel test robot
and Sudip pointed out build failures:

  arm: imx_v6_v7_defconfig and multi_v7_defconfig
  mips: decstation_64_defconfig, decstation_defconfig, decstation_r4k_defconfig

  In file included from crypto/chacha20poly1305.c:13:
  include/crypto/poly1305.h:56:46: error: 'CONFIG_CRYPTO_LIB_POLY1305_RSIZE' undeclared here (not in a function); did you mean 'CONFIG_CRYPTO_POLY1305_MODULE'?
     56 |                 struct poly1305_key opaque_r[CONFIG_CRYPTO_LIB_POLY1305_RSIZE];
        |                                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We could attempt to fix this by listing the dependencies piecemeal, but
it's not as obvious as it looks: drivers like caam use this macro in
headers even if there's no .o compiled in that makes use of it.  So
actually fixing this might require a bit more of a comprehensive
approach, rather than whack-a-mole with hunting down which drivers use
which headers which use this macro.

Therefore, this commit just reverts the change, and maybe the problem
can be visited on the next rainy day.
