8c7d255dd2 bus: omap_l3_smx: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Trivially convert this driver from always returning zero in the remove

same type now as fsl_mc_bus_shutdown() and the only thing the latter
does is to call the former, use fsl_mc_bus_remove() directly as
.shutdown() callback.

864acca580 bus: fsl-mc: Drop if block with always false condition
The mc that belongs to a pdev is always a root dprc. In
fsl_mc_bus_probe() the mc device gets assigned the platform device as
parent. As dev_is_fsl_mc() is false for a platform device,
fsl_mc_get_root_dprc() will always be true and so the if body is never
run and it can be dropped.

The motivation for this change is to get rid of an error path in
.remove() that is broken (because only a part of the necessary cleanup
is done resulting in leaks and/or use-after-frees and the driver core
ignores the return value of .remove().)

385903a7ec SoC driver updates for 6.7
The highlights for the driver support this time are
 
  - Qualcomm platforms gain support for the Qualcomm Secure Execution
    Environment firmware interface to access EFI variables on certain
    devices, and new features for multiple platform and firmware drivers.
 
  - Arm FF-A firmware support gains support for v1.1 specification features,
    in particular notification and memory transaction descriptor changes.
 
  - SCMI firmware support now support v3.2 features for clock and DVFS
    configuration and a new transport for Qualcomm platforms.
 
  - Minor cleanups and bugfixes are added to pretty much all the active
    platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
    atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
    In particular, this contains portions of the treewide conversion to
    use __counted_by annotations and the device_get_match_data helper.

de055e6116 bus: fsl-mc: Replace deprecated strncpy() with strscpy_pad()
`strncpy` is deprecated for use on NUL-terminated destination strings [1].

We need to prefer more robust and less ambiguous string interfaces.

`obj_desc->(type|label)` are expected to be NUL-terminated strings as
per "include/linux/fsl/mc.h +143"
| ...
|  * struct fsl_mc_obj_desc - Object descriptor
|  * @type: Type of object: NULL terminated string
| ...

It seems `cmd_params->obj_type` is also expected to be a NUL-terminated string.

A suitable replacement is `strscpy_pad` due to the fact that it
guarantees NUL-termination on the destination buffer whilst keeping the
NUL-padding behavior that `strncpy` provides.

Padding may not strictly be necessary but let's opt to keep it as this
ensures no functional change.

cb289ce6e2 bus: vexpress-config: Annotate struct vexpress_syscfg_func with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct vexpress_syscfg_func.

e5deb8f76e bus: ti-sysc: Fix SYSC_QUIRK_SWSUP_SIDLE_ACT handling for uart wake-up
The uarts should be tagged with SYSC_QUIRK_SWSUP_SIDLE instead of
SYSC_QUIRK_SWSUP_SIDLE_ACT. The difference is that SYSC_QUIRK_SWSUP_SIDLE
is used to force idle target modules rather than block idle during usage.

The SYSC_QUIRK_SWSUP_SIDLE_ACT should disable autoidle and wake-up when
a target module is active, and configure autoidle and wake-up when a
target module is inactive. We are missing configuring the target module
on sysc_disable_module(), and missing toggling of the wake-up bit.

Let's fix the issue to allow uart wake-up to work.

11729caa52 bus: ti-sysc: Fix missing AM35xx SoC matching
Commit feaa8baee8 ("bus: ti-sysc: Implement SoC revision handling")
created a list of SoC types searching for strings based on names
and wildcards which associates the SoC to different families.

The OMAP34xx and OMAP35xx are treated as SOC_3430 while
OMAP36xx and OMAP37xx are treated as SOC_3630, but the AM35xx
isn't listed.

The AM35xx is mostly an OMAP3430, and a later commit a12315d6d2
("bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specific") looks
for the SOC type and behaves in a certain way if it's SOC_3430.

This caused a regression on the AM3517 causing it to return two
errors:

 ti-sysc: probe of 48318000.target-module failed with error -16
 ti-sysc: probe of 49032000.target-module failed with error -16

Fix this by treating the creating SOC_AM35 and inserting it between
the SOC_3430 and SOC_3630.  If it is treaed the same way as the
SOC_3430 when checking the status of sysc_check_active_timer,
the error conditions will disappear.

d929b2b746 bus: ti-sysc: Use fsleep() instead of usleep_range() in sysc_reset()
The am335x-evm started producing boot errors because of subtle timing
changes:

Unhandled fault: external abort on non-linefetch (0x1008) at 0xf03c1010
...
sysc_reset from sysc_probe+0xf60/0x1514
sysc_probe from platform_probe+0x5c/0xbc
...

The fix consists in using the appropriate sleep function in sysc reset.
For flexible sleeping, fsleep is recommended. Here, sysc delay parameter
can take any value in [0 - 255] us range. As a result, fsleep() should
be used, calling udelay() for a sysc delay lower than 10 us.

1544df9ab4 ARM: SoC drivers for 6.6
The main change this time is the introduction of the drivers/genpd
 subsystem that gets split out from drivers/soc to keep common
 functionality together. Ulf Hansson is taking over maintainership for
 these and is sending a separate pull request with the same commits,
 but they are in the soc drivers tree to avoid conflicts against other
 soc driver patches.
 
 The SCMI driver subsystem gets an update to version 3.2 of the
 specification. There are also updates to memory, reset and other firmware
 drivers.
 
 On the soc driver side, the updates are mostly cleanups across a number
 of Arm platforms. On driver for loongarch adds power management for DT
 based systems, another driver is for HiSilicon's Arm server chips with
 their HCCS system health interface.
 
 The remaining updates for the most part add support for additional
 hardware in existing drivers or contain minor cleanups. Most of these
 are for the Qualcomm Snapdragon platform.

bus: fsl-mc: Use common ranges functions
Since commit 3d5089c426 ("of/address: Add support for 3 address cell
bus"), the DT address functions can handle translating buses with 3
address cells. Replace the custom code with the for_each_of_range()
iterator.

The original code had fallbacks to get "#address-cells"/"#size-cells"
from the bus parent node if they are missing. This is non-standard
behavior, and AFAICT the upstream .dts files never relied on that.

53c5ae638d
bus: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

efe47a18e4 bus: mhi: host: allow MHI client drivers to provide the firmware via a pointer
Currently MHI loads the firmware image from the path provided by client
devices. ath11k needs to support firmware image embedded along with meta
data (named as firmware-2.bin). So allow the client driver to request the
firmware file from user space on it's own and provide the firmware image
data and size to MHI via a pointer struct mhi_controller::fw_data.

This is an optional feature, if fw_data is NULL MHI load the firmware using
the name from struct mhi_controller::fw_image string as before.

Tested with ath11k and WCN6855 hw2.0.

15f6705756 bus: mhi: host: pci_generic: Add support for IP_SW0 channels
IP_SW0 channels are used to transfer data over the networking interface
between MHI endpoint and the host. Define the channels in the MHI v1
channel config along with dedicated event rings.

cabce92dd8 bus: mhi: host: Skip MHI reset if device is in RDDM
In RDDM EE, device can not process MHI reset issued by host. In case of MHI
power off, host is issuing MHI reset and polls for it to get cleared until
it times out. Since this timeout can not be avoided in case of RDDM, skip
the MHI reset in this scenarios.

bus: ixp4xx: fix IXP4XX_EXP_T1_MASK
The IXP4XX_EXP_T1_MASK was shifted one bit to the right, overlapping
IXP4XX_EXP_T2_MASK and leaving bit 29 unused. The offset being wrong is
also confirmed at least by the datasheet of IXP45X/46X [1].

Fix this by aligning it to IXP4XX_EXP_T1_SHIFT.

303c9c63ab bus: fsl-mc: don't assume child devices are all fsl-mc devices
Changes in VFIO caused a pseudo-device to be created as child of
fsl-mc devices causing a crash [1] when trying to bind a fsl-mc
device to VFIO. Fix this by checking the device type when enumerating
fsl-mc child devices.
