Rafael J. Wysocki d674553009 hisi_lpc: Use acpi_dev_for_each_child()
Instead of walking the list of children of an ACPI device directly,
use acpi_dev_for_each_child() to carry out an action for all of
the given ACPI device's children.

This will help to eliminate the children list head from struct
acpi_device as it is redundant and it is used in questionable ways
in some places (in particular, locking is needed for walking the
list pointed to it safely, but it is often missing).

While at it, simplify hisi_lpc_acpi_set_io_res() by making it accept
a struct acpi_device pointer from the caller, instead of going to
struct device and back to get the same result, and clean up confusion
regarding hostdev and its ACPI companion in that function.

Also remove a redundant check from it.

Qiang Yu 1227d2a20c bus: mhi: host: Move IRQ allocation to controller registration phase
During runtime, the MHI endpoint may be powered up/down several times.
So instead of allocating and destroying the IRQs all the time, let's just
enable/disable IRQs during power up/down.

The IRQs will be allocated during mhi_register_controller() and freed
during mhi_unregister_controller(). This works well for things like PCI
hotplug also as once the PCI device gets removed, the controller will
get unregistered. And once it comes back, it will get registered back
and even if the IRQ configuration changes (MSI), that will get accounted.

Shin'ichiro Kawasaki 928ea98252 bus: fsl-mc-bus: fix KASAN use-after-free in fsl_mc_bus_remove()
In fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to
fsl_destroy_mc_io(). However, mc->root_mc_bus_dev is already freed in
fsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io
triggers KASAN use-after-free. To avoid the use-after-free, keep the
reference to mc->root_mc_bus_dev->mc_io in a local variable and pass to
fsl_destroy_mc_io().

This patch needs rework to apply to kernels older than v5.15.

Linus Torvalds 500a434fc5 Driver core changes for 5.19-rc1
Here is the set of driver core changes for 5.19-rc1.
 
 Note, I'm not really happy with this pull request as-is, see below for
 details, but overall this is all good for everything but a small set of
 systems, which we have a fix for already.
 
 Lots of tiny driver core changes and cleanups happened this cycle,
 but the two major things were:
 
 	- firmware_loader reorganization and additions including the
 	  ability to have XZ compressed firmware images and the ability
 	  for userspace to initiate the firmware load when it needs to,
 	  instead of being always initiated by the kernel. FPGA devices
 	  specifically want this ability to have their firmware changed
 	  over the lifetime of the system boot, and this allows them to
 	  work without having to come up with yet-another-custom-uapi
 	  interface for loading firmware for them.
 	- physical location support added to sysfs so that devices that
 	  know this information, can tell userspace where they are
 	  located in a common way.  Some ACPI devices already support
 	  this today, and more bus types should support this in the
 	  future.
 
 Smaller changes included:
 	- driver_override api cleanups and fixes
 	- error path cleanups and fixes
 	- get_abi script fixes
 	- deferred probe timeout changes.
 
 It's that last change that I'm the most worried about.  It has been
 reported to cause boot problems for a number of systems, and I have a
 tested patch series that resolves this issue.  But I didn't get it
 merged into my tree before 5.18-final came out, so it has not gotten any
 linux-next testing.
 
 I'll send the fixup patches (there are 2) as a follow-on series to this
 pull request if you want to take them directly, _OR_ I can just revert
 the probe timeout changes and they can wait for the next -rc1 merge
 cycle.  Given that the fixes are tested, and pretty simple, I'm leaning
 toward that choice.  Sorry this all came at the end of the merge window,
 I should have resolved this all 2 weeks ago, that's my fault as it was
 in the middle of some travel for me.
 
 All have been tested in linux-next for weeks, with no reported issues
 other than the above-mentioned boot time outs.

Linus Torvalds 6f9b5ed8ca Char / Misc / Other smaller driver subsystem updates for 5.19-rc1
Here is the large set of char, misc, and other driver subsystem updates
 for 5.19-rc1.  The merge request for this has been delayed as I wanted
 to get lots of linux-next testing due to some late arrivals of changes
 for the habannalabs driver.
 
 Highlights of this merge are:
 	- habanalabs driver updates for new hardware types and fixes and
 	  other updates
 	- IIO driver tree merge which includes loads of new IIO drivers
 	  and cleanups and additions
 	- PHY driver tree merge with new drivers and small updates to
 	  existing ones
 	- interconnect driver tree merge with fixes and updates
 	- soundwire driver tree merge with some small fixes
 	- coresight driver tree merge with small fixes and updates
 	- mhi bus driver tree merge with lots of updates and new device
 	  support
 	- firmware driver updates
 	- fpga driver updates
 	- lkdtm driver updates (with a merge conflict, more on that
 	  below)
 	- extcon driver tree merge with small updates
 	- lots of other tiny driver updates and fixes and cleanups, full
 	  details in the shortlog.
 
 All of these have been in linux-next for almost 2 weeks with no reported
 problems.
 
 Note, there are 3 merge conflicts when merging this with your tree:
 	- MAINTAINERS, should be easy to resolve
 	- drivers/slimbus/qcom-ctrl.c, should be straightforward
 	  resolution
 	- drivers/misc/lkdtm/stackleak.c, not an easy resolution.  This
 	  has been noted in the linux-next tree for a while, and
 	  resolved there, here's a link to the resolution that Stephen
 	  came up with and that Kees says is correct:
 	  	https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
 
 I will be glad to provide a merge point that contains these resolutions
 if that makes things any easier for you.

Linus Torvalds cc3c470ae4 ARM: driver changes for 5.19
There are minor updates to SoC specific drivers for chips by Rockchip,
 Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom. Noteworthy
 driver changes include:
 
 - Several conversions of DT bindings to yaml format.
 
 - Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.
 
 - Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
   and support for more chips in the RPMh power domains and the soc-id.
 
 - NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.
 
 - Apple M1 gains support for the on-chip NVMe controller, making it
   possible to finally use the internal disks. This also includes SoC
   drivers for their RTKit IPC and for the SART DMA address filter.
 
 For other subsystems that merge their drivers through the SoC tree,
 we have
 
 - Firmware drivers for the ARM firmware stack including TEE, OP-TEE,
   SCMI and FF-A get a number of smaller updates and cleanups. OP-TEE
   now has a cache for firmware argument structures as an optimization,
   and SCMI now supports the 3.1 version of the specification.
 
 - Reset controller updates to Amlogic, ASpeed, Renesas and ACPI drivers
 
 - Memory controller updates for Tegra, and a few updates for other
   platforms.

  - Telit FN990 based on SDX65
  - Foxconn T99W373/T99W368 based on SDX62/SDX65
 
 Core changes:
 
  - During the recycle of event ring elements, compute the ctxt_wp based on the
    local cached value instead of reading from shared memory. This is to prevent
    the possible corruption of the ctxt_wp as some of the endpoint devices could
    modify the value in shared memory.
 
  - Add sysfs support for resetting the endpoint based on the MHI spec. The MHI
    spec allows the host to hard reset the device in the case of an unrecoverable
    error and all other reset mechanisms have failed.
 
  - During MHI shutdown, wait for the endpoint device to enter the ready state
    post reset before proceeding. This is to avoid a possible race where host
    would remove the interrupt handler and device will send ready state
    interrupt, resulting in IOMMU fault.
 
  - Bail out updating the MHI register if the read has failed during
    read/modify/write.
 
  - Use mhi_write_reg() instead of mhi_write_reg_field() for writing the whole
    register fields in mhi_init_mmio().
 
 MAINTAINERS change:
 
  - Since Qualcomm has moved the email domain for its employess from codeaurora
    domain to quicinc, update the same for Hemant.

Arnd Bergmann 3f656f2618 Qualcomm driver updates for v5.19
This converts a wide range of Qualcomm-related DeviceTree bindings to
 YAML, in order to improve our ability to validate the DeviceTree source.
 
 The RPMh power-domain driver gains support for the modem platform SDX65,
 the compute platform SC8280XP and the automotive platform SA8540p. While
 LLCC gains support for SC8180X and SC8280XP and gains a
 MODULE_DEVICE_TABLE() to make it functional as a module.
 
 It adds a driver for configuring the SSC bus, providing Linux access to
 the hardware blocks in the sensor subsystem.
 
 The socinfo driver gets confusion related to MSM8974 Pro sorted out and
 adds new ids for SM8540 and SC7280.
 
 The SCM driver gains support for MSM8974.
 
 Add missing of_node_put() in smp2p and smsm drivers.
 Stop using iterator after list_for_each_entry() and define static
 definitions as such, in the PDR driver.

Lu Baolu 512881eacf bus: platform,amba,fsl-mc,PCI: Add device DMA ownership management
The devices on platform/amba/fsl-mc/PCI buses could be bound to drivers
with the device DMA managed by kernel drivers or user-space applications.
Unfortunately, multiple devices may be placed in the same IOMMU group
because they cannot be isolated from each other. The DMA on these devices
must either be entirely under kernel control or userspace control, never
a mixture. Otherwise the driver integrity is not guaranteed because they
could access each other through the peer-to-peer accesses which by-pass
the IOMMU protection.

This checks and sets the default DMA mode during driver binding, and
cleanups during driver unbinding. In the default mode, the device DMA is
managed by the device driver which handles DMA operations through the
kernel DMA APIs (see Documentation/core-api/dma-api.rst).

For cases where the devices are assigned for userspace control through the
userspace driver framework(i.e. VFIO), the drivers(for example, vfio_pci/
vfio_platfrom etc.) may set a new flag (driver_managed_dma) to skip this
default setting in the assumption that the drivers know what they are
doing with the device DMA.

Calling iommu_device_use_default_domain() before {of,acpi}_dma_configure
is currently a problem. As things stand, the IOMMU driver ignored the
initial iommu_probe_device() call when the device was added, since at
that point it had no fwspec yet. In this situation,
{of,acpi}_iommu_configure() are retriggering iommu_probe_device() after
the IOMMU driver has seen the firmware data via .of_xlate to learn that
it actually responsible for the given device. As the result, before
that gets fixed, iommu_use_default_domain() goes at the end, and calls
arch_teardown_dma_ops() if it fails.

Commit e8604b1447 introduced a call to the helper function
msi_first_desc(), which needs MSI descriptor mutex lock before
call. However, the required mutex lock was not added. This results in
lockdep assertion:

Fix this by adding the mutex lock and unlock around the function call.

Manivannan Sadhasivam 5301258899 bus: mhi: ep: Add support for reading from the host
Data transfer between host and the ep device happens over the transfer
ring associated with each bi-directional channel pair. Host defines the
transfer ring by allocating memory for it. The read and write pointer
addresses of the transfer ring are stored in the channel context.

Once host places the elements in the transfer ring, it increments the
write pointer and rings the channel doorbell. Device will receive the
doorbell interrupt and will process the transfer ring elements.

This commit adds support for reading the transfer ring elements from
the transfer ring till write pointer, incrementing the read pointer and
finally sending the completion event to the host through corresponding
event ring.
