* [PATCH v3 5/5] arm64: dts: rockchip: add reset property for dwc3 controllers on rk3399.
From: Enric Balletbo i Serra @ 2017-12-15 11:00 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171215110005.7564-1-enric.balletbo@collabora.com>
After commit '06c47e6286d usb: dwc3: of-simple: Add support to get resets
for the device' you can add the reset property to the dwc3 node, the reset
is required for the controller to work properly, otherwise bind / unbind
stress testing of the USB controller on rk3399 we'd often end up with lots
of failures that looked like this:
phy phy-ff800000.phy.9: phy poweron failed --> -110
dwc3 fe900000.dwc3: failed to initialize core
dwc3: probe of fe900000.dwc3 failed with error -110

I mean,
The v2 exactly has a bug which may cause the CSI writing frame to
a wrong memory address.
BTW, should I send a new version. I have made some improve sine v3.

right, I should have said that it doesn't guarantee that an already
signalled interrupt will have been retired prior to enabling interrupts
on the CPU again.

Yes, it definitely indicates the intention of the code and the flow, and
the fact that we have to work around delayed signals in the ISR is then
something we can describe with a comment there.
I'll add an ISB in the other version of the patch I sent before.

* [PATCH 25/25] arm: ste: dts: Remove leading 0x and 0s from bindings notation
From: Mathieu Malaterre @ 2017-12-15 11:16 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171215111620.20379-1-malat@debian.org>
Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:
https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve as a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"
This is a follow up to commit 4c9847b7375a ("dt-bindings: Remove leading 0x from bindings notation")

Hi Jirka,
When you say reasonable size for x86, I ran a string duplication finder
on the x86 JSONs and the results show a huge amount of duplication.
Please check this:
https://gist.githubusercontent.com/johnpgarry/68bc87e823ae2ce0f7b475b4e55e5795/raw/f4cea138999d8b34151b9586d733592e01774d7a/x86%2520JSON%2520duplication
Extract:
"Found a 65 line (311 tokens) duplication in the following files:

/linux/tools/perf/pmu-events/arch/x86/broadwellx/bdx-metrics.json"
Won't this all potentially have a big maintainence cost?
For example, I saw multiple JSON update patches which look identical:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/tools/perf/pmu-events/arch/x86?h=v4.15-rc3&id=7347bba5552f479d4292ffd008d18d41a965f021

I just don't know how this schema scales with more archs and more
platforms supported. It's just early days now...

Interesting if I apply that to v4.14 and then flatten the new code for CONFIG_ARM64_SVE=n, I get:
Working:
void fpsimd_update_current_state(struct fpsimd_state *state)
{
local_bh_disable();
fpsimd_load_state(state);
if (test_and_clear_thread_flag(TIF_FOREIGN_FPSTATE)) {
struct fpsimd_state *st = ¤t->thread.fpsimd_state;
__this_cpu_write(fpsimd_last_state.st, st);
st->cpu = smp_processor_id();
}
local_bh_enable();
}
Broken:
void fpsimd_update_current_state(struct fpsimd_state *state)
{
struct fpsimd_last_state_struct *last;
struct fpsimd_state *st;
local_bh_disable();
current->thread.fpsimd_state = *state;
fpsimd_load_state(¤t->thread.fpsimd_state);
if (test_and_clear_thread_flag(TIF_FOREIGN_FPSTATE)) {
last = this_cpu_ptr(&fpsimd_last_state);
st = ¤t->thread.fpsimd_state;
last->st = st;
last->sve_in_use = test_thread_flag(TIF_SVE);
st->cpu = smp_processor_id();
}
local_bh_enable();
}
Can you try my flattened "broken" version by itself and see if that does
reproduce the bug? If not, my flattening may be making bad assumptions...
Assuming the "broken" version reproduces the bug, I can't yet see exactly
where the breakage comes from.
The two important differences here seem to be
1) Staging the state via current->thread.fpsimd_state instead of loading
directly:
- fpsimd_load_state(state);
+ current->thread.fpsimd_state = *state;
+ fpsimd_load_state(¤t->thread.fpsimd_state);
and
2) Using this_cpu_ptr() + assignment instead of __this_cpu_write() when
reassociating the task's fpsimd context with the cpu:
{
+ struct fpsimd_last_state_struct *last;
+ struct fpsimd_state *st;
[...]
if (test_and_clear_thread_flag(TIF_FOREIGN_FPSTATE)) {
- struct fpsimd_state *st = ¤t->thread.fpsimd_state;
-
- __this_cpu_write(fpsimd_last_state.st, st);
- st->cpu = smp_processor_id();
+ last = this_cpu_ptr(&fpsimd_last_state);
+ st = ¤t->thread.fpsimd_state;
+
+ last->st = st;
+ last->sve_in_use = test_thread_flag(TIF_SVE);
+ st->cpu = smp_processor_id();
}
I can't see why either of these breaks anything yet.
Can you try them independently and see whether you can isolate the

I think that to solve this problem, we need to stop treating
clocksources and clockevent devices as completely separate device types,
and instead treat them as particular cases of a more general clock
device.
That way, a driver can register a single device, with flags saying
whether it is:
* a clocksource only
* a clockevent device only
* both a clocksource and clockevent device
* both, but mutually exclusive at runtime
... and thus drivers don't have to make an impossible decision up-front
as to how the device should be used.
As more devices get registered, the core timekeeping code can improve on
its choices and re-assign devices.
That doesn't solve the case where a clock device may use resources we
want for something else, but I think we can solve that separately.
Thanks,
Mark.

Could you elaborate on the chaining case? I haven't encountered that,
and at the moment I'm not sure I follow how that works.

I guess that might work for the boot-time overlay case, where the user
knows ahead-of-time that there will be a conflict for resources, but
that doesn't help with the dynamic overlay case, since the user can't
know what conflicts there will be.
Can we attempt to unregister the clock device in that case, when the PWM
is requested? If the timekeeping core can select another device, then
we're free to use this one as a PWM. If not, then we're stuck anyway.
Thanks,
Mark.

* [PATCH 0/2] Use SPDX-License-Identifier for rockchip devicetree files
From: Klaus Goger @ 2017-12-15 11:44 UTC (permalink / raw)
To: linux-arm-kernel
This patch series replaces all the license text in rockchip devicetree
files text with a proper SPDX-License-Identifier.
It follows the guidelines submitted[1] by Thomas Gleixner that are not
yet merged.
These series also fixes the issue with contradicting statements in most
licenses. The introduction text claims to be GPL or X11[2] but the
following verbatim copy of the license is actually a MIT[3] license.
The X11 license includes a advertise clause and trademark information
related to the X Consortium. As these X Consortium specfic points are
irrelevant for us we stick with the actuall license text.

Update all 64bit rockchip devicetree files to use SPDX-License-Identifiers.
All devicetrees claim to be either GPL or X11 while the actual license
text is MIT. Therefore we use MIT for the SPDX tag as X11 is clearly
wrong.

Indeed yes the code added here is literally just above the code
that selects that, it should be fairly simple to update the patch
to take this into account.

We probably want the special case on there being no clock at all
which should silently proceed as this code does and then actual
errors and PROBE_DEFERs can log and fail.

* [PATCH 0/4 v5] Support bridge timings
From: Linus Walleij @ 2017-12-15 12:10 UTC (permalink / raw)
To: linux-arm-kernel
This patch set is in response to Laurent's mail:
https://www.spinics.net/lists/dri-devel/msg155618.html
So in summary:
- The connector is apparently not the right abstraction to carry
the detailed timings specification between DRI drivers and bridge
drivers.
- Instead put detailed timing data into the bridge itself as an
optional information pointer.
- Add fields to specify triggering edge on the clock, setup
and hold time for the bridge.
- Augment the dumb VGA driver with this data, supporting a few
ADV and TI variants.
- Augment the PL111 driver to use this data to figure out if it
needs to clock out display data on the negative edge rather
than the positive edge because the current clocking out on the
positive edge obviously partly misses the setup->hold window,
as can be observed in annoying green flicker.
Linus Walleij (4):
drm/bridge: Add bindings for TI THS8134
drm/bridge: Provide a way to embed timing info in bridges
drm/bridge: Add timing support to dumb VGA DAC

* [PATCH 1/4 v5] drm/bridge: Add bindings for TI THS8134
From: Linus Walleij @ 2017-12-15 12:10 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171215121047.3650-1-linus.walleij@linaro.org>
This adds device tree bindings for the Texas Instruments
THS8134, THS8134A and THS8134B VGA DACs by extending and
renaming the existing bindings for THS8135.
These DACs are used for the VGA outputs on the ARM reference
designs such as Integrator, Versatile and RealView.

ChangeLog v2->v5:
- Dropped the "ti,ths813x" as it turns out we need precise info
about the sub-variant anyways as they all very in timings.
- Refine the THS8134 variants, it turns out ths8134, ths8134a
and ths8134b are three different variants of ths8134.
ChangeLog v1->v2:
- Introduce specific-to-general compatible string:
compatible = "ti,ths8134a", "ti,ths813x";
so drivers can handle the whole family the same way.
- Collected Rob's ACK.

* [PATCH 2/4 v5] drm/bridge: Provide a way to embed timing info in bridges
From: Linus Walleij @ 2017-12-15 12:10 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171215121047.3650-1-linus.walleij@linaro.org>
After some discussion and failed patch sets trying to convey
the right timing information between the display engine and
a bridge using the connector, I try instead to use an optional
timing information container in the bridge itself, so that
display engines can retrieve it from any bridge and use it to
determine how to drive outputs.

* [PATCH 3/4 v5] drm/bridge: Add timing support to dumb VGA DAC
From: Linus Walleij @ 2017-12-15 12:10 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171215121047.3650-1-linus.walleij@linaro.org>
This extends the dumb VGA DAC bridge to handle the THS8134A
and THS8134B VGA DACs in addition to those already handled.
We assign the proper timing data to the pointer inside the
bridge struct so display controllers that need to align their
timings to the bridge can pick it up and work from there.

ChangeLog v1->v2:
- Alphabetize includes
- Use a u32 with the bus polarity flags and just encode the
polarity using the DRM define directly.
- Rename vendor_data to vendor_info.
- Simplify assignment of the flag as it is just a simple
u32 now.
- Probe all TI variants on the "ti,ths813x" wildcard for now,
we only need to know that the device is in this family to
set the clock edge flag right.

* [PATCH 4/4 v5] drm/pl111: Support handling bridge timings
From: Linus Walleij @ 2017-12-15 12:10 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <20171215121047.3650-1-linus.walleij@linaro.org>
If the bridge has a too strict setup time for the incoming
signals, we may not be fast enough and then we need to
compensate by outputting the signal on the inverse clock
edge so it is for sure stable when the bridge samples it.
Since bridges in difference to panels does not expose their
connectors, make the connector optional in the display
setup code.

* [PATCH] arm64: rockchip: enable Rockchip IO domain support
From: Klaus Goger @ 2017-12-15 12:20 UTC (permalink / raw)
To: linux-arm-kernel
Make sure the IO domain support is active. This requires to enable
Adaptive Voltage Scaling class support too.
Without Rockchip IO domain support the internal level shifter on the RK3399
will be misconfigured if used in the other voltage domain then the default.
