296455ade1 Char/Misc and other Driver changes for 6.8-rc1
Here is the big set of char/misc and other driver subsystem changes for
 6.8-rc1.  Lots of stuff in here, but first off, you will get a merge
 conflict in drivers/android/binder_alloc.c when merging this tree due to
 changing coming in through the -mm tree.
 
 The resolution of the merge issue can be found here:
 	https://lore.kernel.org/r/20231207134213.25631ae9@canb.auug.org.au
 or in a simpler patch form in that thread:
 	https://lore.kernel.org/r/ZXHzooF07LfQQYiE@google.com
 
 If there are issues with the merge of this file, please let me know.
 
 Other than lots of binder driver changes (as you can see by the merge
 conflicts) included in here are:
  - lots of iio driver updates and additions
  - spmi driver updates
  - eeprom driver updates
  - firmware driver updates
  - ocxl driver updates
  - mhi driver updates
  - w1 driver updates
  - nvmem driver updates
  - coresight driver updates
  - platform driver remove callback api changes
  - tags.sh script updates
  - bus_type constant marking cleanups
  - lots of other small driver updates
 
 All of these have been in linux-next for a while with no reported issues
 (other than the binder merge conflict.)

Christian A. Ehrhardt
4dde835698 of: Fix double free in of_parse_phandle_with_args_map
In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.

Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".

Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.

Fixes: bd6f2fd5a1 ("of: Support parsing phandle argument lists through a nexus node")

7f38b70042 of: device: Export of_device_make_bus_id()
This helper is really handy to create unique device names based on their
device tree path, we may need it outside of the OF core (in the NVMEM
subsystem) so let's export it. As this helper has nothing patform
specific, let's move it to of/device.c instead of of/platform.c so we
can add its prototype to of_device.h.

3310288f61 of/platform: Disable sysfb if a simple-framebuffer node is found
Some DT platforms use EFI to boot and in this case the EFI Boot Services
may register a EFI_GRAPHICS_OUTPUT_PROTOCOL handle, that will later be
queried by the Linux EFI stub to fill the global struct screen_info data.

The data is used by the Generic System Framebuffers (sysfb) framework to
add a platform device with platform data about the system framebuffer.

But if there is a "simple-framebuffer" node in the DT, the OF core will
also do the same and add another device for the system framebuffer.

This could lead for example, to two platform devices ("simple-framebuffer"
and "efi-framebuffer") to be added and matched with their corresponding
drivers. So both efifb and simpledrm will be probed, leading to following:

[    0.055752] efifb: framebuffer at 0xbd58dc000, using 16000k, total 16000k
[    0.055755] efifb: mode is 2560x1600x32, linelength=10240, pages=1
[    0.055758] efifb: scrolling: redraw
[    0.055759] efifb: Truecolor: size=2:10:10:10, shift=30:20:10:0
...
[    3.295896] simple-framebuffer bd58dc000.framebuffer: [drm] *ERROR*
could not acquire memory range [??? 0xffff79f30a29ee40-0x2a5000001a7
flags 0x0]: -16
[    3.298018] simple-framebuffer: probe of bd58dc000.framebuffer
failed with error -16

To prevent the issue, make the OF core to disable sysfb if there is a node
with a "simple-framebuffer" compatible. That way only this device will be
registered and sysfb would not attempt to register another one using the
screen_info data even if this has been filled.

This seems the correct thing to do in this case because:

a) On a DT platform, the DTB is the single source of truth since is what
   describes the hardware topology. Even if EFI Boot Services are used to
   boot the machine.

b) The of_platform_default_populate_init() function is called in the
   arch_initcall_sync() initcall level while the sysfb_init() function
   is called later in the subsys_initcall() initcall level.

73ae308801 of: address: Consolidate bus .map() functions
The bus .map() functions vary only by checking the flag cells values
and skipping over any flag cells to read the addresses. Otherwise they
all do the same reading 'ranges' address and size and returning the
address's offset if it is within the 'ranges' entry.

Refactor all the .map() functions to pass in the flag cell size so that
each bus can check the bus specific flags and then call a common
function to do everything else.

42604f8eb7 of: address: Fix address translation when address-size is greater than 2
With the recent addition of of_pci_prop_ranges() in commit 407d1a5192
("PCI: Create device tree node for bridge"), the ranges property can
have a 3 cells child address, a 3 cells parent address and a 2 cells
child size.

A range item property for a PCI device is filled as follow:
  <BAR_nbr> 0 0 <phys.hi> <phys.mid> <phys.low> <BAR_sizeh> <BAR_sizel>
  <-- Child --> <-- Parent (PCI definition) --> <- BAR size (64bit) -->

This allow to translate BAR addresses from the DT. For instance:
pci@0,0 {
  #address-cells = <0x03>;
  #size-cells = <0x02>;
  device_type = "pci";
  compatible = "pci11ab,100", "pciclass,060400", "pciclass,0604";
  ranges = <0x82000000 0x00 0xe8000000
            0x82000000 0x00 0xe8000000
	    0x00 0x4400000>;
  ...
  dev@0,0 {
    #address-cells = <0x03>;
    #size-cells = <0x02>;
    compatible = "pci1055,9660", "pciclass,020000", "pciclass,0200";
    /* Translations for BAR0 to BAR5 */
    ranges = <0x00 0x00 0x00 0x82010000 0x00 0xe8000000 0x00 0x2000000
              0x01 0x00 0x00 0x82010000 0x00 0xea000000 0x00 0x1000000
              0x02 0x00 0x00 0x82010000 0x00 0xeb000000 0x00 0x800000
              0x03 0x00 0x00 0x82010000 0x00 0xeb800000 0x00 0x800000
              0x04 0x00 0x00 0x82010000 0x00 0xec000000 0x00 0x20000
              0x05 0x00 0x00 0x82010000 0x00 0xec020000 0x00 0x2000>;
    ...
    pci-ep-bus@0 {
      #address-cells = <0x01>;
      #size-cells = <0x01>;
      compatible = "simple-bus";
      /* Translate 0xe2000000 to BAR0 and 0xe0000000 to BAR1 */
      ranges = <0xe2000000 0x00 0x00 0x00 0x2000000
                0xe0000000 0x01 0x00 0x00 0x1000000>;
      ...
    };
  };
};

During the translation process, the "default-flags" map() function is
used to select the matching item in the ranges table and determine the
address offset from this matching item.
This map() function simply calls of_read_number() and when address-size
is greater than 2, the map() function skips the extra high address part
(ie part over 64bit). This lead to a wrong matching item and a wrong
offset computation.
Also during the translation itself, the extra high part related to the
parent address is not present in the translated address.

Fix the "default-flags" map() and translate() in order to take into
account the child extra high address part in map() and the parent extra
high address part in translate() and so having a correct address
translation for ranges patterns such as the one given in the example
above.

ca5a75df36 amba: bus: balance firmware node reference counting
Currently the ACPI code doesn't bump the reference count of
the firmware node, while OF counter part does. Not that it's
a problem right now, since ACPI doesn't really use the reference
counting for firmware nodes, it still makes sense to make code
robust against any changes done there. For this,
 - switch ACPI case to use device_set_node() to be unified with OF
 - move reference counting to amba_device_add()
 - switch to use firmware nodes instead of OF ones

In the result we will have reference counting done in the same module
for all callers independently on the nature of firmware node behind.

5a7319b967 of: unittest: Fix of_unittest_pci_node() kconfig dependencies
of_unittest_pci_node test depends on both CONFIG_PCI_DYNAMIC_OF_NODES
and CONFIG_OF_OVERLAY. Move the test into the existing
CONFIG_OF_OVERLAY ifdef and rework the CONFIG_PCI_DYNAMIC_OF_NODES
dependency to use IS_ENABLED() instead. This reduces the combinations to
build.

121b83eadd of: unittest-data: Convert remaining overlay DTS files to sugar syntax
Overlay syntactic sugar for generating target-path fragments is
supported by the version of dtc supplied with the kernel since commit
50aafd6089 ("scripts/dtc: Update to upstream version
v1.4.6-21-g84e414b0b5bc").  Hence convert the remaining unittest overlay
devicetree source files to sugar syntax, improving readability.

This completes the work started in commit db2f3762d6 ("of: convert

0676aeeca5 of: unittest: Cleanup partially-applied overlays
When of_overlay_fdt_apply() fails, the changeset may be partially
applied, and the caller is still expected to call of_overlay_remove() to
clean up this partial state.  However, overlay_17 is the only test that
takes care of cleaning up after an (expected) failure.

Instead of adding cleanup code to each individual test, extend
overlay_info with the optional expected return value of
of_overlay_remove(), and handle cleanup in the overlay_data_apply()
helper.  While at it, simplify the end marker in the overlay_info table.

Update the expected error output for errors during the newly cleanup.

The removal check in of_unittest_apply_revert_overlay_check()
always uses the platform device overlay type, while it should use the
actual overlay type, as passed as a parameter to the function.

This has no impact on any current test, as all tests calling
of_unittest_apply_revert_overlay_check() use the platform device overlay
type.

a9515ff4fb of: overlay: Call of_changeset_init() early
When of_overlay_fdt_apply() fails, the changeset may be partially
applied, and the caller is still expected to call of_overlay_remove() to
clean up this partial state.

However, of_overlay_apply() calls of_resolve_phandles() before
init_overlay_changeset().  Hence if the overlay fails to apply due to an
unresolved symbol, the overlay_changeset.cset.entries list is still
uninitialized, and cleanup will crash with a NULL-pointer dereference in
overlay_removal_is_ok().

Fix this by moving the call to of_changeset_init() from
init_overlay_changeset() to of_overlay_fdt_apply(), where all other
early initialization is done.

47284862bf of: overlay: Extend of_overlay_fdt_apply() to specify the target node
Currently, in an overlay fdt fragment, it needs to specify the exact
location in base DT. In another word, when the fdt fragment is generated,
the base DT location for the fragment is already known.

There is new use case that the base DT location is unknown when fdt
fragment is generated. For example, the add-on device provide a fdt
overlay with its firmware to describe its downstream devices. Because it
is add-on device which can be plugged to different systems, its firmware
will not be able to know the overlay location in base DT. Instead, the
device driver will load the overlay fdt and apply it to base DT at runtime.
In this case, of_overlay_fdt_apply() needs to be extended to specify
the target node for device driver to apply overlay fdt.
    int overlay_fdt_apply(..., struct device_node *base);
