[WHY]
Previously as MPO + ODM Combine was not supported, finding secondary pipes
for each case was mutually exclusive. Now that both are supported at the same
time, both cases should be taken into account when finding a secondary pipe.
[HOW]
If a secondary pipe cannot be found based on previous bottom pipe,
search for a second pipe using next_odm_pipe instead.

This crash happens because we're trying to read registers from the
regmap beyond the length of the mapping created by ioremap().
The number of hdmi_rdma_channels determines the size of the regmap via
this code in sound/soc/qcom/lpass-cpu.c:
lpass_hdmi_regmap_config.max_register = LPAIF_HDMI_RDMAPER_REG(variant, variant->hdmi_rdma_channels);
According to debugfs the size of the regmap is 0x68010 but according to
the DTS file posted in [1] the size is only 0x68000 (see the first reg
property of the lpass_cpu node). Let's change the number of channels to
be 3 instead of 4 so the math works out to have a max register of
0x67010, nicely fitting inside of the region size of 0x68000.
Note: I tried to bump up the size of the register region to the next
page to include the 0x68010 register but then the tail command caused
SErrors with an async abort, implying that the register region doesn't
exist or it isn't clocked because the bus is telling us that the
register read failed. I reduce the number of channels and played audio
through the HDMI channel and it kept working so I think this is correct.

Currently, requesting kernel FPU access doesn't distinguish which parts of
the extended ("FPU") state are needed. This is nice for simplicity, but
there are a few cases in which it's suboptimal:
- The vast majority of in-kernel FPU users want XMM/YMM/ZMM state but do
not use legacy 387 state. These users want MXCSR initialized but don't
care about the FPU control word. Skipping FNINIT would save time.
(Empirically, FNINIT is several times slower than LDMXCSR.)
- Code that wants MMX doesn't want or need MXCSR initialized.
_mmx_memcpy(), for example, can run before CR4.OSFXSR gets set, and
initializing MXCSR will fail because LDMXCSR generates an #UD when the
aforementioned CR4 bit is not set.
- Any future in-kernel users of XFD (eXtended Feature Disable)-capable
dynamic states will need special handling.
Add a more specific API that allows callers to specify exactly what they
want.

KSZ8794CNX datasheet section 8.0 RESET CIRCUIT describes recommended
circuit for interfacing with CPU/FPGA reset consisting of 10k pullup
resistor and 10uF capacitor to ground. This circuit takes ~100 ms to
rise enough to release the reset.
For maximum supply voltage VDDIO=3.3V VIH=2.0V R=10kR C=10uF that is
VDDIO - VIH
t = R * C * -ln( ------------- ) = 10000*0.00001*-(-0.93)=0.093 s

so we need ~95 ms for the reset to really de-assert, and then the
original 100us for the switch itself to come out of reset. Simply
msleep() for 100 ms which fits the constraint with a bit of extra
space.

The KSZ8795 switch has 4 external ports {0,1,2,3} and 1 CPU port {4}, so
does the KSZ8765. The KSZ8794 seems to be repackaged KSZ8795 with different
ID and port 3 not routed out, however the port 3 registers are present in
the silicon, so the KSZ8794 switch has 3 external ports {0,1,2} and 1 CPU
port {4}. Currently the driver always uses the last port as CPU port, on
KSZ8795/KSZ8765 that is port 4 and that is OK, but on KSZ8794 that is port
3 and that is not OK, as it must also be port 4.
This patch adjusts the driver such that it always registers a switch with
5 ports total (4 external ports, 1 CPU port), always sets the CPU port to
switch port 4, and then configures the external port mask according to
the switch model -- 3 ports for KSZ8794 and 4 for KSZ8795/KSZ8765.

LPASS driver is partially broken on DragonBoard DB410c on 5.10 and
its totally broken on other Supported Qualcomm SoCs.
This was due to DAI ids being over written by the SoC specific header files
in the dt-bindings.
Idea of having SoC specific headers is not doable when we are dealing with
a common driver. So this patchset attempts to fix this properly by creating
a common dt-bindings header for lpass which can be updated with new entries
if required. This patchset also add an simple of_xlate function to resolve
the dai names and different SoCs might not have 1:1 mapping for the
dai_driver array with dai ids.
Changes since v1:
- removed array indexes as suggested by Stephan G.
- rebased to sound/for-next branch
- collected Srinivasa tested-by tag for sc7180 platform.

2.30.0.284.gd98b1dd5eaa7-goog
This series adds unit tests for ASoC topology.
First fix problems found when developing and running test cases and
then add tests implementation.
Tests themselves are quite simple and just call
snd_soc_tplg_component_load() with various parameters and check the
result. Tests themselves are described in more detail in commits
adding them.
Goal is to expand the amount of test cases in following patches.
Prerequisity for this patchset are 2 patches which have already been
sent:
https://lore.kernel.org/alsa-devel/20210114163602.911205-1-amadeuszx.slawinski@linux.intel.com/T/#t
Description on how typical test case itself works:
In order to load topology we need to have 3 things:
card, codec component & platform component.
In typical test case we register card and platform component and bind
to dummy codec. There are of course execeptions, when we want to
test behaviour of topology API when component or card is missing.
Note that this is bit different from typical scenario (in SOF and skylake
drivers) where card is registered by machine driver and component by
platform driver, as we register both when setting up test.
If you check the test case most of them have similar architecture of:
1.
/* run test */
ret = snd_soc_register_card(&kunit_comp->card);
if (ret != 0 && ret != -EPROBE_DEFER)
KUNIT_FAIL(test, "Failed to register card");
2.
ret = snd_soc_component_initialize(&kunit_comp->comp, &test_component, test_dev);
KUNIT_EXPECT_EQ(test, 0, ret);
3.
ret = snd_soc_add_component(&kunit_comp->comp, NULL, 0);
KUNIT_EXPECT_EQ(test, 0, ret);
Ad. 1.
First we register card, which in most tests returns -EPROBE_DEFER
(from snd_soc_bind_card()), as platform component is not yet created.
I test for both 0 and -EPROBE_DEFER, as it makes it easier to reshuffle
this code around if needed and there is one test case which does it in
different order.
Ad. 2.
Then we initialize platform component with structure pointing at proper
probe function, which calls snd_soc_tplg_component_load() with test
parameters and checks expected result.
Ad. 3.
And then in follow up we call snd_soc_add_component() which creates
platform component for us and calls snd_soc_try_rebind_card() which
if everything is bound properly calls previously set probe function.

2.25.1
The OMAP driver may leverage software BCH logic to locate errors while
using its own hardware to detect the presence of errors. This is
achieved with a "mixed" mode which initializes manually the software
BCH internal logic while providing its own OOB layout.
The issue here comes from the fact that the BCH driver has been
updated to only use generic NAND objects, and no longer depend on raw
NAND structures as it is usable from SPI-NAND as well. However, at the
end of the BCH context initialization, the driver checks the validity
of the OOB layout. At this stage, the raw NAND fields have not been
populated yet while being used by the layout helpers, leading to an
invalid layout.
The chosen solution here is to include the BCH structure definition
and to refer to the BCH fields directly (de-referenced as a const
pointer here) to know as early as possible the number of steps and ECC
bytes which have been chosen.
Note: I don't know which commit exactly triggered the error, but the
entire migration to a generic BCH driver got merged in one go, so this
should not be a problem for stable backports.

Since the recent refactoring, it's been reported that some USB-audio
devices (typically webcams) are no longer detected properly by
PulseAudio. The debug session revealed that it's failing at probing
by PA to try the sample rate 44.1kHz while the device has discrete
sample rates other than 44.1kHz. But the puzzle was that arecord
works as is, and some other devices with the discrete rates work,
either.
After all, this turned out to be the lack of the dependencies in a few
hw constraint rules: snd_pcm_hw_rule_add() has the (variable)
arguments specifying the dependent parameters, and some functions
didn't set the target parameter itself as the dependencies. This
resulted in an invalid parameter that could be generated only in a
certain call pattern. This bug itself has been present in the code,
but it didn't trigger errors just because the rules were casually
avoiding such a corner case. After the recent refactoring and
cleanup, however, the hw constraints work "as expected", and the
problem surfaced now.
For fixing the problem above, this patch adds the missing dependent
parameters to each snd_pcm_hw_rule() call.

This reverts commit b2d2440430.
It's true that creating rxe on top of 802.1q interfaces doesn't work.
Thus, commit fd49ddaf7e ("RDMA/rxe: prevent rxe creation on top of vlan
interface") was absolutely correct.
But b2d2440430 was incorrect assuming that with this change, RDMA and
VLAN don't work togehter at all. It just has to be set up
differently. Rather than creating rxe on top of the VLAN interface, rxe
must be created on top of the physical interface. RDMA then works just
fine through VLAN interfaces on top of that physical interface, via the
"upper device" logic.
This is hard to see in the rxe logic because it never talks about vlan,
but instead rxe carefully selects upper vlan netdevices when working with
packets which in turn imply certain vlan tagging. This is all done
correctly and interacts with the gid table with VLAN support the same as
real HW does.
b2d2440430 broke this setup deliberately and should thus be
reverted. Also, b2d2440430 removed rxe_dma_device(), so adapt the revert
to discard that hunk.

Multicast entries in the MAC table use the high bits of the MAC
address to encode the ports that should get the packets. But this port
mask does not work for the CPU port, to receive these packets on the
CPU port the MAC_CPU_COPY flag must be set.
Because of this IPv6 was effectively not working because neighbor
solicitations were never received. This was not apparent before commit
9403c158 (net: mscc: ocelot: support IPv4, IPv6 and plain Ethernet mdb
entries) as the IPv6 entries were broken so all incoming IPv6
multicast was then treated as unknown and flooded on all ports.
To fix this problem rework the ocelot_mact_learn() to set the
MAC_CPU_COPY flag when a multicast entry that target the CPU port is
added. For this we have to read back the ports endcoded in the pseudo
MAC address by the caller. It is not a very nice design but that avoid
changing the callers and should make backporting easier.

Receiving ACK with a valid SYN cookie, cookie_v4_check() allocates struct
request_sock and then can allocate inet_rsk(req)->ireq_opt. After that,
tcp_v4_syn_recv_sock() allocates struct sock and copies ireq_opt to
inet_sk(sk)->inet_opt. Normally, tcp_v4_syn_recv_sock() inserts the full
socket into ehash and sets NULL to ireq_opt. Otherwise,
tcp_v4_syn_recv_sock() has to reset inet_opt by NULL and free the full
socket.
The commit 01770a1661 ("tcp: fix race condition when creating child
sockets from syncookies") added a new path, in which more than one cores
create full sockets for the same SYN cookie. Currently, the core which
loses the race frees the full socket without resetting inet_opt, resulting
in that both sock_put() and reqsk_put() call kfree() for the same memory:
sock_put
sk_free
__sk_free
sk_destruct
__sk_destruct
sk->sk_destruct/inet_sock_destruct
kfree(rcu_dereference_protected(inet->inet_opt, 1));
reqsk_put
reqsk_free
__reqsk_free
req->rsk_ops->destructor/tcp_v4_reqsk_destructor
kfree(rcu_dereference_protected(inet_rsk(req)->ireq_opt, 1));
Calling kmalloc() between the double kfree() can lead to use-after-free, so
this patch fixes it by setting NULL to inet_opt before sock_put().
As a side note, this kind of issue does not happen for IPv6. This is
because tcp_v6_syn_recv_sock() clones both ipv6_opt and pktopts which
correspond to ireq_opt in IPv4.

The allocation uses sizeof(u32) when it should use sizeof(unsigned long)
so it leads to memory corruption later in the function when the data is
initialized.

BIT_WIDTH field in I2S_CTL register is two bits wide, however
recent regmap field conversion patch trimmed it down to one bit.
Fix this by correcting the bit range!

lpass hdmi support patch totally removed support for MI2S TERTIARY
and QUATERNARY.
One of the major issue was spotted with the design of having
separate SoC specific header files for the common lpass driver.
This design is prone to break as an when new SoC header is added
as the common DAI ids of other SoCs will be overwritten by the
new ones.
Having a common header qcom,lpass.h should fix the issue and any new
DAI ids should be added to the common header.
With this change lpass also needs a new of_xlate function to resolve
dai name.

Existing header file design of having separate SoC specific header files
for the common lpass driver has mutiple issues.
This design is prone to break as an when new SoC header is added
as the common DAI ids of other SoCs will be overwritten by the
new ones.
One of them surfaced by recent patch that adds support to sc7180, this
one totally broke LPASS drivers on other Qualcomm SoCs.
Before this gets worst, fix this by having a common header qcom,lpass.h.
This should fix the issue and any new DAI ids should be added to the
common header. This will be more sustainable then the existing design!
