[PATCH v2 00/17] Arm cpu schema clean-ups

[PATCH v2 00/17] Arm cpu schema clean-ups

[Rob Herring (Arm)]

The Arm cpu.yaml schema fails to restrict allowed properties in 'cpu' 
nodes. The result, not surprisely, is a number of additional properties 
and errors in .dts files. This series resolves those issues.

There's still more properties in arm32 DTS files which I have not 
documented. Mostly yet more supply names and "fsl,soc-operating-points". 
What's a few more warnings on the 10000s of warnings...

The .dts files can be taken by the respective SoC maintainers. I will 
take the binding changes.

v2:
 - Drop applied "arm64: dts: morello: Fix-up cache nodes"
 - Rework enable-method schema
 - Drop "arm: dts: qcom: msm8916: Move "qcom,acc" and "qcom,saw" to 32-bit .dtsi"
 - Keep qcom,saw and qcom,acc properties on msm8939
 - Fix qcom,saw2.yaml example
 - Fix power-domain-names to be "perf" on qcom sdx55/65

[PATCH v2 01/17] arm64: dts: allwinner: h5/h6: Drop spurious 'clock-latency-ns' properties

[Rob Herring (Arm)]

'clock-latency-ns' is not a valid property for CPU nodes. It belongs in
OPP table (which has it). Drop them from the CPU nodes.

[PATCH v2 02/17] arm64: dts: broadcom: bcm2712: Use "l2-cache" for L2 cache node names

[Rob Herring (Arm)]

There's no need include the CPU number in the L2 cache node names as
the names are local to the CPU nodes. The documented node name is
also just "l2-cache".

[PATCH v2 06/17] arm64: dts: qcom: msm8992-lg-h815: Fix CPU node "enable-method" property dependencies

[Rob Herring (Arm)]

The "spin-table" enable-method requires "cpu-release-addr" property,
so add a dummy entry. It is assumed the bootloader will fill in the
correct values.

[PATCH v2 07/17] arm: dts: qcom: sdx55/sdx65: Fix CPU power-domain-names

"rpmhpd" is not documented nor used anywhere. The power-domain is used
for performance scaling (cpufreq), so "perf" is the correct name to use.

[PATCH v2 08/17] arm/arm64: dts: imx: Drop redundant CPU "clock-latency"

[Rob Herring (Arm)]

The "clock-latency" property is part of the deprecated opp-v1 binding
and is redundant if the opp-v2 table has equal or larger values in any
"clock-latency-ns". The OPP tables have values of 150000, so it can be
removed.

[PATCH v2 11/17] arm64: dts: amlogic: Drop redundant CPU "clock-latency"

[Rob Herring (Arm)]

The "clock-latency" property is part of the deprecated opp-v1 binding
and is redundant if the opp-v2 table has equal or larger values in any
"clock-latency-ns". Add any missing "clock-latency-ns" properties and
remove "clock-latency".

[PATCH v2 12/17] dt-bindings: arm/cpus: Add schemas for "enable-method" dependencies

[Rob Herring (Arm)]

Replace the prose for properties dependent on specific "enable-method"
values with schemas defining the same requirements.

Both "qcom,acc" and "qcom,saw" properties appear to be required for any
of the Qualcomm enable-method values, so the schema is a bit simpler
than what the text said. The properties are also needed on some Qualcomm
platforms with other enable-method values. It's limited to Cortex A53
based platforms so use that to disable the properties. The references
to arm/msm/qcom,saw2.txt and arm/msm/qcom,kpss-acc.txt are out of date,
so just drop them.

Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
Reviewed-by: Sudeep Holla <sudeep.holla@arm.com>
---
v2:
 - Only disallow qcom,acc and qcom,saw on !cortex-a53
 - Fix example in qcom,saw2.yaml

[PATCH v2 13/17] dt-bindings: arm/cpus: Re-wrap 'description' entries

[Rob Herring (Arm)]

Some of the 'description' entries have odd line wrapping and incorrect
YAML block modifiers. The 'description' entries should typically wrap
at 80 chars. Reformat the entries to follow that along with using '>'
modifiers as appropriate.

[PATCH v2 14/17] dt-bindings: Reference opp-v1 schema in CPU schemas

[Rob Herring (Arm)]

The opp-v1 binding is only used in MIPS and arm32 CPU nodes, so add a
$ref to it in the CPU schemas and drop the "select".

As opp-v1 has long been deprecated, mark it as such.

[PATCH v2 15/17] dt-bindings: arm/cpus: Add missing properties

[Rob Herring (Arm)]

The Arm CPU schema is missing a number of properties already in use.
This has gone unnoticed as extra properties have not been restricted.
Add a missing reference to cpu.yaml, and add all the missing properties.

As "clock-latency" and "voltage-tolerance" are related to opp-v1, add
those properties to the opp-v1.yaml schema.

With this, other properties can be prevented from creeping in with
'unevaluatedProperties: false'.

-Binding for MediaTek's CPUFreq driver
-=====================================
-
-Required properties:
-- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock names.
-- clock-names: Should contain the following:
-	"cpu"		- The multiplexer for clock input of CPU cluster.
-	"intermediate"	- A parent of "cpu" clock which is used as "intermediate" clock
-			  source (usually MAINPLL) when the original CPU PLL is under
-			  transition and not stable yet.
-	Please refer to Documentation/devicetree/bindings/clock/clock-bindings.txt for
-	generic clock consumer properties.
-- operating-points-v2: Please refer to Documentation/devicetree/bindings/opp/opp-v2.yaml
-	for detail.
-- proc-supply: Regulator for Vproc of CPU cluster.
-
-Optional properties:
-- sram-supply: Regulator for Vsram of CPU cluster. When present, the cpufreq driver
-	       needs to do "voltage tracking" to step by step scale up/down Vproc and
-	       Vsram to fit SoC specific needs. When absent, the voltage scaling
-	       flow is handled by hardware, hence no software "voltage tracking" is
-	       needed.
-- mediatek,cci:
-	Used to confirm the link status between cpufreq and mediatek cci. Because
-	cpufreq and mediatek cci could share the same regulator in some MediaTek SoCs.
-	To prevent the issue of high frequency and low voltage, we need to use this
-	property to make sure mediatek cci is ready.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.16/arm64-dt)

[11/17] arm64: dts: amlogic: Drop redundant CPU "clock-latency"
        https://git.kernel.org/amlogic/c/4bc28af2da876531e5183d25ae807e608c816d18

These changes has been applied on the intermediate git tree [1].

The v6.16/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.

This is already applied, guess I forgot to merge it into the branch that

Sometimes I check next, but in this case I just looked at replies for
which there were none. I dislike submitting dts changes because it's a
range of AWOL maintainers, only applying around some rcN (so up to 2
months later), silently applying, and applied but never in linux-next
(until in soc tree).

Looks like there is a problem in MAINTAINERS. This matches what b4 runs:

Let's add "send the b4 ty email" to the list of things that I did not
do, but thought that I had done.
