The clock controller on Meson8, Meson8b and Meson8m2 is very similar
based on the code from the Amlogic GPL kernel sources. Add separate
compatibles for each SoC to make sure that we can easily implement
all the small differences for each SoC later on.
In general the Meson8 and Meson8m2 seem to be almost identical as they
even share the same mach-meson8 directory in Amlogic's GPL kernel
sources.
The main clocks on Meson8, Meson8b and Meson8m2 are very similar,
because they are all using the same PLL values, 90% of the clock gates
are the same (the actual diffstat of the mach-meson8/clock.c and
mach-meson8b/clock.c files is around 30 to 40 lines, when excluding
all commented out code).
The difference between the Meson8 and Meson8b clock gates seem to be:
- Meson8 has AIU_PCLK, HDMI_RX, VCLK2_ENCT, VCLK2_ENCL, UART3,
CSI_DIG_CLKIN gates which don't seem to be available on Meson8b
- the gate on Meson8 for bit 7 seems to be named "_1200XXX" instead
of "PERIPHS_TOP" (on Meson8b)
- Meson8b has a SANA gate which doesn't seem to exist on Meson8 (or
on Meson8 the same bit is used by the UART3 gate in Amlogic's GPL
kernel sources)
None of these gates is added for now, since it's unclear whether these
definitions are actually correct (the VCLK2_ENCT gate for example is
defined, but only used in some commented block).
The main difference between all three SoCs seem to be the video (VPU)
clocks. Apart from different supported clock rates (according to vpu.c
in mach-meson8 and mach-meson8b from Amlogic's GPL kernel sources) the
most notable difference is that Meson8m2 has a GP_PLL clock and a mux
(probably the same as on the Meson GX SoCs) to support glitch-free
(clock rate) switching.
None of these VPU clocks are not supported by our mainline meson8b
clock driver yet though.

In design of ALSA PCM core, status and control data for runtime of ALSA
PCM substream are shared between kernel/user spaces by page frame
mapping with read-only attribute. Both of hardware-side and
application-side position on PCM buffer are maintained as a part of
the status data. In a view of ALSA PCM application, these two positions
can be updated by executing ioctl(2) with some commands.
There's an event of tracepoint for hardware-side position; 'hwptr'.
On the other hand, no events for application-side position. This commit
adds a new event for this purpose; 'applptr'. When the application-side
position is changed in kernel space, this event is probed with useful
information for developers.
I note that the event is not probed for all of ALSA PCM applications, When
applications are written by read/write programming scenario, the event is
surely probed. The applications execute ioctl(2) with
SNDRV_PCM_IOCTL_[READ|WRITE][N/I]_FRAMES to read/write any PCM frame, then
ALSA PCM core updates the application-side position in kernel land.
However, when applications are written by mmap programming scenario, if
maintaining the application side position in kernel space accurately,
applications should voluntarily execute ioctl(2) with
SNDRV_PCM_IOCTL_SYNC_PTR to commit the number of handled PCM frames. If
not voluntarily, the application-side position is not changed, thus the
added event is not probed.
There's a loophole, using architectures to which ALSA PCM core judges
non cache coherent. In this case, the status and control data is not mapped
into processe's VMA for any applications. Userland library, alsa-lib, is
programmed for this case. It executes ioctl(2) with
SNDRV_PCM_IOCTL_SYNC_PTR command every time to requiring the status and
control data.
ARM is such an architecture. Below is an example with serial sound interface
(ssi) on i.mx6 quad core SoC. I use v4.1 kernel released by fsl-community
with patches from VIA Tech. Inc. for VAB820, and my backport patches for
relevant features for this patchset. I use Ubuntu 17.04 from
ports.ubuntu.com as user land for armhf architecture.

We can see 7 calls of ioctl(2) with SNDRV_PCM_IOCTL_SYNC_PTR per loop with
call of poll(2). 128 PCM frames are transferred per loop of one poll(2),
because the PCM substream is configured with S16_LE format and 1 channel
(2 byte * 1 * 128 = 256 bytes). This equals to the size of period of PCM
buffer. Comparing to the probed data, one of the 7 calls of ioctl(2) is
actually used to commit the number of copied PCM frames to kernel space.
The other calls are just used to check runtime status of PCM substream;
e.g. XRUN.
The tracepoint event is useful to investigate this case. I note that below
modules are related to the above sample.
* snd-soc-dummy.ko
* snd-soc-imx-sgtl5000.ko
* snd-soc-fsl-ssi.ko
* snd-soc-imx-pcm-dma.ko
* snd-soc-sgtl5000.ko
My additional note is lock acquisition. The event is probed under acquiring
PCM stream lock. This means that calculation in the event is free from
any hardware events.

Many drivers bind the sequencer stuff in off-load by another driver
module, so that it's loaded only on demand. In the current code, this
mechanism doesn't work when the driver is built-in while the sequencer
is module. We check with IS_REACHABLE() and enable only when the
sequencer is in the same level of build.
However, this is basically a overshoot. The binder code
(snd-seq-device) is an individual module from the sequencer core
(snd-seq), and we just have to make the former a built-in while
keeping the latter a module for allowing the scenario like the above.
This patch achieves that by rewriting Kconfig slightly. Now, a driver
that provides the manual sequencer device binding should select
CONFIG_SND_SEQ_DEVICE in a way as
select SND_SEQ_DEVICE if SND_SEQUENCER != n
Note that the "!=n" is needed here to avoid the influence of the
sequencer core is module while the driver is built-in.
Also, since rawmidi.o may be linked with snd_seq_device.o when
built-in, we have to shuffle the code to make the linker happy.
(the kernel linker isn't smart enough yet to handle such a case.)
That is, snd_seq_device.c is moved to sound/core from sound/core/seq,
as well as Makefile.
Last but not least, the patch replaces the code using IS_REACHABLE()
with IS_ENABLED(), since now the condition meets always when enabled.

The implementation details for SCPI seems to suggest that the sensor
readings must be reported by SCP using a well defined scale
(millidegree Celsius for temperature, millivolts for voltage,
milliamperes for current, microwatts for power and microjoules for
energy).
This is also important for the interaction with other subsystems: for
example both the thermal sub-system and the hwmon sysfs interface expect
the temperature expressed in millidegree Celsius.
Unfortunately since this behaviour is dependent on the firmware
implementation there are cases where the sensor readings are reported
using a different scale. For example in the Amlogic SoCs the
temperature is reported in degree and not millidegree Celsius.
To take into account this discrepancy and fixup the values reported by
SCP a new compatible 'amlogic,meson-gxbb-scpi-sensors' is introduced and
used in this patch by the scpi-hwmon driver to convert the sensor
readings to the expected scale.

The aspeed-pwm-tacho controller supports measuring the fan tach by using
leading, falling, or both edges. This change allows the driver to
support either of the three configurations and will appropriately modify
the returned tach data.
If the controller is measuring with both edges it can return a value more
quickly to the requestor. This version of the driver should still take ~1s
to return with an RPM value per fan, however, it can be tuned faster with
double edge counting enabled than without.
I tested this and found the number returned matched what I expected.

Pull key subsystem fixes from James Morris:
"Here are a bunch of fixes for Linux keyrings, including:
- Fix up the refcount handling now that key structs use the
refcount_t type and the refcount_t ops don't allow a 0->1
transition.
- Fix a potential NULL deref after error in x509_cert_parse().
- Don't put data for the crypto algorithms to use on the stack.
- Fix the handling of a null payload being passed to add_key().
- Fix incorrect cleanup an uninitialised key_preparsed_payload in
key_update().
- Explicit sanitisation of potentially secure data before freeing.
- Fixes for the Diffie-Helman code"

Commit abb2ea7dfd ("compiler, clang: suppress warning for unused
static inline functions") just caused more warnings due to re-defining
the 'inline' macro.
So undef it before re-defining it, and also add the 'notrace' attribute
like the gcc version that this is overriding does.
Maybe this makes clang happier.

Make use of recently implemented stack_depth tracking for arm64 JIT,
so that stack usage can be reduced heavily for programs not using
tail calls at least.

This patch fixes two issues:
1) When forwarding on *,G mroutes that are in a vrf, the
kernel was dropping information about the actual incoming
interface when calling ip_mr_forward from ip_mr_input.
This caused ip_mr_forward to send the multicast packet
back out the incoming interface. Fix this by
modifying ip_mr_forward to be handed the correctly
resolved dev.
2) When a unresolved cache entry is created we store
the incoming skb on the unresolved cache entry and
upon mroute resolution from the user space daemon,
we attempt to forward the packet. Again we were
not resolving to the correct incoming device for
a vrf scenario, before calling ip_mr_forward.
Fix this by resolving to the correct interface
and calling ip_mr_forward with the result.

This series provides updates to mlx5 header rewrite feature, from Or Gerlitz.
and three more small updates From maor and eran.
-------
Or says:
Packets belonging to flows which are different by matching may still need
to go through the same header re-writes (e.g set the current routing hop
MACs and issue TTL decrement). To minimize the number of modify header
IDs, we add a cache for header re-write IDs which is keyed by the binary
chain of modify header actions.
The caching is supported for both eswitch and NIC use-cases, where the
actual conversion of the code to use caching comes in separate patches,
one per use-case.
Using a per field mask field, the TC pedit action supports modifying
partial fields. The last patch enables offloading that.
-------
From Maor, update flow table commands layout to the latest HW spec.
From Eran, ethtool connector type reporting updates.
Thanks,
Saeed.
