e7b0b847de PCI/AER: Clear only ERR_NONFATAL bits during non-fatal recovery
pci_cleanup_aer_uncorrect_error_status() is called by driver .slot_reset()
methods when handling ERR_NONFATAL errors.  Previously this cleared *all*
the bits, including ERR_FATAL bits.

Since we're only handling ERR_NONFATAL errors, clear only the ERR_NONFATAL
error status bits.

7ab92e89bf PCI/AER: Clear only ERR_FATAL status bits during fatal recovery
During recovery from fatal errors, we previously called
pci_cleanup_aer_uncorrect_error_status(), which cleared *all* uncorrectable
error status bits (both ERR_FATAL and ERR_NONFATAL).

Instead, call a new pci_aer_clear_fatal_status() that clears only the
ERR_FATAL bits (as indicated by the PCI_ERR_UNCOR_SEVER register).

40999f11ce tipc: make link capability update thread safe
The commit referred to below introduced an update of the link
capabilities field that is not safe. Given the recently added
feature to remove idle node and link items after 5 minutes, there
is a small risk that the update will happen at the very moment the
targeted link is being removed. To avoid this we have to perform
the update inside the node item's write lock protection.

fe1053b785 drm/amdgpu: rework suspend and resume to deal with atomic changes
Use the newly split ip suspend functions to do suspend displays
first (to deal with atomic so that FBs can be unpinned before
attempting to evict vram), then evict vram, then suspend the
other IPs.  Also move the non-DC pinning code to only be
called in the non-DC cases since atomic should take care of
DC.

7766484b4a drm/amdgpu: Fix warning in dma_fence_is_later on resume from S3.
Problem:
amdgpu_ttm_set_buffer_funcs_status destroys adev->mman.entity on suspend
without releasing adev->mman.bdev.man[TTM_PL_VRAM].move fence
so on resume the new drm_sched_entity.fence_context causes
the warning against the old fence context which is different.

Fix:
When destroying sched_entity in amdgpu_ttm_set_buffer_funcs_status
release  man->move and set the pointer to NULL.

4d3b9ae50e drm/amdgpu: lock and unlock console only for amdgpu_fbdev_set_suspend [V5]
[Why]
While the console_lock is held, console output will be buffered, till
its unlocked it wont be emitted, hence its ideal to unlock sooner to enable
debugging/detecting/fixing of any issue in the remaining sequence of events
in resume path.
The concern here is about consoles other than fbcon on the device,
e.g. a serial console

[How]
This patch restructures the console_lock, console_unlock around
amdgpu_fbdev_set_suspend() and moves this new block appropriately.

V2: Kept amdgpu_fbdev_set_suspend after pci_set_power_state
V3: Updated the commit message to clarify the real concern that this patch
    addresses.
V4: code clean-up.
V5: fixed return value

73449daf8f filesystem-dax: Set page->index
In support of enabling memory_failure() handling for filesystem-dax
mappings, set ->index to the pgoff of the page. The rmap implementation
requires ->index to bound the search through the vma interval tree. The
index is set and cleared at dax_associate_entry() and
dax_disassociate_entry() time respectively.

226ab56107 device-dax: Convert to vmf_insert_mixed and vm_fault_t
Use new return type vm_fault_t for fault and huge_fault handler. For
now, this is just documenting that the function returns a VM_FAULT value
rather than an errno.  Once all instances are converted, vm_fault_t will
become a distinct type.

Commit 1c8f422059 ("mm: change return type to vm_fault_t")

Previously vm_insert_mixed() returned an error code which driver mapped into
VM_FAULT_* type. The new function vmf_insert_mixed() will replace this
inefficiency by returning VM_FAULT_* type.

regulator: qcom_spmi: Fix warning Bad of_node_put()
For of_find_node_by_name(), you typically pass what the previous call
returned. Therefore, of_find_node_by_name() increases the refcount of
the returned node, and decreases the refcount of the node passed as the
first argument.

of_find_node_by_name() is incorrectly used, and produces a warning.
Fix the warning by using the more suitable function
of_get_child_by_name().

Also add a missing of_node_put() for the returned value, since this was
previously being leaked.

and clocks provided on the pads.

On this SoC, each stream direction provides 4 serial lanes. This makes
a maximum of 8 channels in i2s modes and 128 channels in DSP modes.

While each lanes operate on the same slot number (same bit clock), they
may have different TDM masks. This requires to provide a function to let
the card set the 4 masks, in lieu of the usual set_tdm_slots() callback

ASoC: meson: add tdm formatter base driver
Add Amlogic's axg TDM core driver. On this SoC, tdm is bit more
complex than usual, mainly because the different TDM input decoders can
be attached to any of TDM pad interface, including the output pads.

For the this, TDM on this SoC is modeled like this:
- TDM interface provides the DAIs the codecs will be attached to.
  The main responsibility of this driver is to manage the pad format
  and the TDM clock rates.
- TDM Formatters: These are the entities which are actually dealing with
  the TDM signal. TDMOUT produce a TDM signal from the audio sample
  provided by FRDDR using the clocks provided the TDM interface. TDMIN
  feeds TODDR with audio sample using the clocks and TDM signal provided
  by the TDM Interface.
- TDM Streams: This provides the link between 1 DAI stream of the TDM
  interface and one (or more) TDM formatters.

This driver provides the TDM formatter and TDM stream operations.

c8acfe0aad USB: serial: cp210x: implement GPIO support for CP2102N
This patch adds GPIO support for CP2102N devices.

It introduces new generic code to support emulating separate
input and outputs directions even though these devices
only know output modes (open-drain and pushpull). Existing
GPIO support for CP2105 has been migrated over to the new
code structure.

Only limitation is that for the QFN28 variant, only 4 out of
7 GPIOs are supported. This is because the config array
locations of the last 3 pins are not documented, and reverse
engineering revealed offsets that conflicted with other
documented functions. Hence we'll play it safe instead
until somebody clears this up further.
