Pull sound updates from Takashi Iwai:
 "Lots of changes in this cycle, but mostly for cleanups and
  refactoring.

  Significant amount of changes are about DT schema conversions for ASoC
  at this time while we see other usual suspects, too.

  Some highlights below:

  Core:
   - Re-introduction of PCM sync ID support API
   - MIDI2 time-base extension in ALSA sequencer API

  ASoC:
   - Syncing of features between simple-audio-card and the two
     audio-graph cards
   - Support for specifying the order of operations for components
     within cards to allow quirking for unusual systems
   - Lots of DT schema conversions
   - Continued SOF/Intel updates for topology, SoundWire, IPC3/4
   - New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest
     Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS v2.5
     and WCD937x, Realtek RT1318 and RT1320 and Texas Instruments
     PCM5242

  HD-audio:
   - More quirks, Intel PantherLake support, senarytech codec support
   - Refactoring of Cirrus codec component-binding

  Others:
   - ALSA control kselftest improvements, and fixes for input value
     checks in various drivers"

2024-07-04T11:24:58+00:00

qmc_chan_get_byphandle() and the resource managed version retrieve a
channel from a simple phandle.

Extend the API and introduce qmc_chan_get_byphandles_index() and the
resource managed version in order to retrieve a channel from a phandle
list using the provided index to identify the phandle in the list.

Also update qmc_chan_get_byphandle() and the resource managed version to
use qmc_chan_get_byphandles_index() and so avoid code duplication.

dim: make DIMLIB dependent on NET

2024-06-26T00:15:06+00:00

DIMLIB's capabilities are supplied by the dim, net_dim, and
rdma_dim objects, and dim's interfaces solely act as a base for
net_dim and rdma_dim and are not explicitly used anywhere else.
rdma_dim is utilized by the infiniband driver, while net_dim
is for network devices, excluding the soc/fsl driver.

In this patch, net_dim relies on some NET's interfaces, thus
DIMLIB needs to explicitly depend on the NET Kconfig.

The soc/fsl driver uses the functions provided by net_dim, so
it also needs to depend on NET.

 "Including fixes from CAN, netfilter, wireguard and IPsec.

  I'd like to highlight [ lowlight? - Linus ] Florian W stepping down as
  a netfilter maintainer due to constant stream of bug reports. Not sure
  what we can do but IIUC this is not the first such case.

  Current release - regressions:

   - rxrpc: fix use of page_frag_alloc_align(), it changed semantics and
     we added a new caller in a different subtree

   - xfrm: allow UDP encapsulation only in offload modes

  Current release - new code bugs:

   - tcp: fix refcnt handling in __inet_hash_connect()

   - Revert "net: Re-use and set mono_delivery_time bit for userspace
     tstamp packets", conflicted with some expectations in BPF uAPI

  Previous releases - regressions:

   - ipv4: raw: fix sending packets from raw sockets via IPsec tunnels

   - devlink: fix devlink's parallel command processing

   - veth: do not manipulate GRO when using XDP

   - esp: fix bad handling of pages from page_pool

  Previous releases - always broken:

   - report RCU QS for busy network kthreads (with Paul McK's blessing)

   - tcp/rds: fix use-after-free on netns with kernel TCP reqsk

   - virt: vmxnet3: fix missing reserved tailroom with XDP

  Misc:

   - couple of build fixes for Documentation"

 "These are changes that for some reason ended up not making it into the

   - A rework of the omap clock support that touches both drivers and

   - The reset controller branch changes that had a dependency on late
     bugfixes. Merging them here avoids a backmerge of 6.8-rc5 into the
     drivers branch

soc: fsl: dpio: fix kcalloc() argument order

2024-03-13T16:17:32+00:00

A previous bugfix added a call to kcalloc(), which starting in gcc-14
causes a harmless warning about the argument order:

drivers/soc/fsl/dpio/dpio-service.c: In function 'dpaa2_io_service_enqueue_multiple_desc_fq':
drivers/soc/fsl/dpio/dpio-service.c:526:29: error: 'kcalloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
  526 |         ed = kcalloc(sizeof(struct qbman_eq_desc), 32, GFP_KERNEL);
      |                             ^~~~~~
drivers/soc/fsl/dpio/dpio-service.c:526:29: note: earlier argument should specify number of elements, later size of each element

Since the two are only multiplied, the order does not change the
behavior, so just fix it now to shut up the compiler warning.

Dmity independently came up with the same fix.

soc: fsl: qbman: Use raw spinlock for cgr_lock

2024-03-13T08:12:02+00:00

smp_call_function always runs its callback in hard IRQ context, even on
PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock
for cgr_lock to ensure we aren't waiting on a sleeping task.

Although this bug has existed for a while, it was not apparent until
commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change")
which invokes smp_call_function_single via qman_update_cgr_safe every
time a link goes up or down.
