No, not unless the prior descriptions of the hardware have been wildly
inaccurate - my understanding had been that the DCDC was a normal DCDC
with an analogue input intended to be biased to set the output voltage
(presumably in terms of a full rail supply) and that the PWM had been
connected to this analogue input. If the PWM is supplying the DCDC then
the hardware design just seems bizzare, I can't see how this would even
work.

That doesn't matter. They are at different levels in the hierarchy.

Please fix your mail client configuration, it is not marking quoted
material as quoted and there's no word wrapping which makes everything

There's also random stuff like the above appearing in the mail.
I strongly suggest working with some of your colleagues who are more

Don't just add unfinished code that does nothing useful - that just
wastes everyone's time and makes the driver harder to review. I'm
fairly sure that if people are able to implement jack detection they
will be able to figure out the fairly trivial code that's here and of
course this is something that when it's done should be just a driver
feature accessed through normal driver APIs.

So, do you use codespell tool for that? I would suggest to use that tool
and propose any fix there first. At least that tool has a good history
of changes back in forward until some native speaker(s) settle some
cases.

No need to use dot at the end of one-liner comments

/*

Also I would leave

Without dots here. AFAIU they are used to better distinguish group of
definitions inside headers (that's why 3 lines).

I'm almost fine with the change itself, but people may be concerned in:
1) what is the value of the change (would be nice to put this in commit
message);
2) how much additional work this change may bring for backported fixes
if any;
3) native speakers are the best who can re-read this and Ack.

* [PATCH] ARM: dts: Add missing CPU frequencies for Exynos5422/5800
From: Bartlomiej Zolnierkiewicz @ 2016-12-13 16:52 UTC (permalink / raw)
To: Krzysztof Kozlowski
Cc: Mark Rutland, devicetree, linux-samsung-soc, linux-pm, Ben Gamari,
linux-kernel, Russell King, Rob Herring, Doug Anderson,
Javier Martinez Canillas, Kukjin Kim, Thomas Abraham,
Andreas Faerber, linux-arm-kernel
Add missing 2000MHz & 1900MHz OPPs (for A15 cores) and 1400MHz OPP
(for A7 cores). Also update common Odroid-XU3 Lite/XU3/XU4 thermal
cooling maps to account for new OPPs.
Since new OPPs are not available on all Exynos5422/5800 boards modify
dts files for Odroid-XU3 Lite (limited to 1.8 GHz / 1.3 GHz) & Peach
Pi (limited to 2.0 GHz / 1.3 GHz) accordingly.
Tested on Odroid-XU3 and XU3 Lite.

The purpose of this patch is to fix some comments and styling issues in the
existing code. What is being made here is:
- Sorted the headers files
- Corrected the commentary format
- Reverse tree style in the variables declaration as long as possible
- Add/remove empty lines if needed (style)
- Fix of two misspelled words

I think a more proper explanation would be:
The cpu's supply regulator is specified at the board level, hence we
need to add a label to it to reference it without replicating the whole
tree structure.

"timer" is already used in stm32 DT for clocksource node... It is also why
I use "timers" for this.

+CS35L35 Speaker Amplifier
+
+Required properties:
+
+ - compatible : "cirrus,cs35l35"
+
+ - reg : the I2C address of the device for I2C
+
+ - VA-supply, VP-supply : power supplies for the device,
+ as covered in
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+
+ - interrupt-parent : Specifies the phandle of the interrupt controller to
+ which the IRQs from CS35L35 are delivered to.
+ - interrupts : IRQ line info CS35L35.
+ (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+ for further information relating to interrupt properties)
+
+Optional properties:
+ - cirrus,reset-gpios : Active low GPIO used to reset the amplifier
+
+ - cirrus,stereo-config : Boolean to determine if there are 2 AMPs for a
+ Stereo configuration
+
+ - cirrus,audio-channel : Set Location of Audio Signal on Serial Port
+ 0 = Data Packet received on Left I2S Channel
+ 1 = Data Packet received on Right I2S Channel
+
+ - cirrus,advisory-channel : Set Location of Advisory Signal on Serial Port
+ 0 = Data Packet received on Left I2S Channel
+ 1 = Data Packet received on Right I2S Channel
+
+ - cirrus,shared-boost : Boolean to enable ClassH tracking of Advisory Signal
+ if 2 Devices share Boost BST_CTL
+
+ - cirrus,sp-drv-strength : Value for setting the Serial Port drive strength
+ Table 3-10 of the datasheet lists drive-strength specifications
+ 0 = 1x (Default)
+ 1 = .5x
+
+ - cirrus,bst-pdn-fet-on : Boolean to determine if the Boost PDN control
+ powers down with a rectification FET On or Off. If VSPK is supplied
+ externally then FET is off.
+
+ - cirrus,boost-ctl-millivolt : Boost Converter control word. Step Size of 100mV
+ 0x00 = (Default) VP
+ 0x01 = 2600mV
+ 0x41 = 9000mV
+
+ - cirrus,boost-ipk-milliamp : Boost-converter peak current limit.
+ Configures the peak current by monitoring the current through the boost FET.
+ Step size: 112mA
+ 0x00 = 1680mA
+ 0x19 = 4480mA
+
+ - cirrus,amp-gain-zc : Boolean to determine if to use Amplifier gain-change
+ zero-cross
+
+Optional H/G Algorithm sub-node:
+
+ The cs35l35 node can have a single "cirrus,classh-internal-algo" sub-node
+ that will disable automatic control of the internal H/G Algorithm.
+
+ It is strongly recommended that the Datasheet be referenced when adjusting
+ or using these Class H Algorithm controls over the internal Algorithm.
+ Serious damage can occur to the Device and surrounding components.
+
+ - cirrus,classh-internal-algo : Sub-node for the Internal Class H Algorithm
+ See Section 4.3 Internal Class H Algorithm in the Datasheet.
+ If not used, the device manages the ClassH Algorithm internally.
+
+Optional properties for the "cirrus,classh-internal-algo" Sub-node
+
+ Section 7.29 Class H Control
+ - cirrus,classh-bst-overide : Boolean
+ - cirrus,classh-bst-max-limit
+ - cirrus,classh-mem-depth
+
+ Section 7.30 Class H Headroom Control
+ - cirrus,classh-headroom
+
+ Section 7.31 Class H Release Rate
+ - cirrus,classh-release-rate
+
+ Section 7.32 Class H Weak FET Drive Control
+ - cirrus,classh-wk-fet-disable
+ - cirrus,classh-wk-fet-delay
+ - cirrus,classh-wk-fet-thld
+
+ Section 7.34 Class H VP Control
+ - cirrus,classh-vpch-auto
+ - cirrus,classh-vpch-rate
+ - cirrus,classh-vpch-man
+
+Optional Monitor Signal Format sub-node:
+
+ The cs35l35 node can have a single "cirrus,monitor-signal-format" sub-node
+ for adjusting the Depth, Location and Frame of the Monitoring Signals
+ for Algorithms.
+
+ See Sections 4.8.2 through 4.8.4 Serial-Port Control in the Datasheet
+
+ -cirrus,monitor-signal-format : Sub-node for the Monitor Signaling Formating
+ on the I2S Port. Each of the 3 8 bit values in the array contain the settings
+ for depth, location, and frame.
+
+ If not used, the defaults for the 6 monitor signals is used.
+
+ Sections 7.44 - 7.53 lists values for the depth, location, and frame
+ for each monitoring signal.
+
+ - cirrus,imon : 3 8 bit values to set the depth, location, and frame
+ of the IMON monitor signal.
+
+ - cirrus,vmon : 3 8 bit values to set the depth, location, and frame
+ of the VMON monitor signal.
+
+ - cirrus,vpmon : 3 8 bit values to set the depth, location, and frame
+ of the VPMON monitor signal.
+
+ - cirrus,vbstmon : 3 8 bit values to set the depth, location, and frame
+ of the VBSTMON monitor signal
+
+ - cirrus,vpbrstat : 3 8 bit values to set the depth, location, and frame
+ of the VPBRSTAT monitor signal
+
+ - cirrus,zerofill : 3 8 bit values to set the depth, location, and frame\
+ of the ZEROFILL packet in the monitor signal
+
+Example:
+
+cs35l35: audio-codec@20 {
+ compatible = "cirrus,cs35l35";
+ reg = <0x20>;
+ VA-supply = <&dummy_vreg>;

IIUC any label should be fine and I don't see anything in the driver
looking for such label name. All I see is it looks for cpu0 regulator
for *legacy* DTs

You need this as you add the same label in the following patches. The
commit message sounds like cpufreq-dt search for that label by name.

+CS35L35 Speaker Amplifier
+
+Required properties:
+
+ - compatible : "cirrus,cs35l35"
+
+ - reg : the I2C address of the device for I2C
+
+ - VA-supply, VP-supply : power supplies for the device,
+ as covered in
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+
+ - interrupt-parent : Specifies the phandle of the interrupt controller to
+ which the IRQs from CS35L35 are delivered to.
+ - interrupts : IRQ line info CS35L35.
+ (See Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+ for further information relating to interrupt properties)
+
+Optional properties:
+ - cirrus,reset-gpios : Active low GPIO used to reset the amplifier
+
+ - cirrus,stereo-config : Boolean to determine if there are 2 AMPs for a
+ Stereo configuration
+
+ - cirrus,audio-channel : Set Location of Audio Signal on Serial Port
+ 0 = Data Packet received on Left I2S Channel
+ 1 = Data Packet received on Right I2S Channel
+
+ - cirrus,advisory-channel : Set Location of Advisory Signal on Serial Port
+ 0 = Data Packet received on Left I2S Channel
+ 1 = Data Packet received on Right I2S Channel
+
+ - cirrus,shared-boost : Boolean to enable ClassH tracking of Advisory Signal
+ if 2 Devices share Boost BST_CTL
+
+ - cirrus,sp-drv-strength : Value for setting the Serial Port drive strength
+ Table 3-10 of the datasheet lists drive-strength specifications
+ 0 = 1x (Default)
+ 1 = .5x
+
+ - cirrus,bst-pdn-fet-on : Boolean to determine if the Boost PDN control
+ powers down with a rectification FET On or Off. If VSPK is supplied
+ externally then FET is off.
+
+ - cirrus,boost-ctl-millivolt : Boost Converter control word. Step Size of 100mV
+ 0x00 = (Default) VP
+ 0x01 = 2600mV
+ 0x41 = 9000mV
+
+ - cirrus,boost-ipk-milliamp : Boost-converter peak current limit.
+ Configures the peak current by monitoring the current through the boost FET.
+ Step size: 112mA
+ 0x00 = 1680mA
+ 0x19 = 4480mA
+
+ - cirrus,amp-gain-zc : Boolean to determine if to use Amplifier gain-change
+ zero-cross
+
+Optional H/G Algorithm sub-node:
+
+ The cs35l35 node can have a single "cirrus,classh-internal-algo" sub-node
+ that will disable automatic control of the internal H/G Algorithm.
+
+ It is strongly recommended that the Datasheet be referenced when adjusting
+ or using these Class H Algorithm controls over the internal Algorithm.
+ Serious damage can occur to the Device and surrounding components.
+
+ - cirrus,classh-internal-algo : Sub-node for the Internal Class H Algorithm
+ See Section 4.3 Internal Class H Algorithm in the Datasheet.
+ If not used, the device manages the ClassH Algorithm internally.
+
+Optional properties for the "cirrus,classh-internal-algo" Sub-node
+
+ Section 7.29 Class H Control

+ - cirrus,classh-vpch-rate
+ - cirrus,classh-vpch-man
+
+Optional Monitor Signal Format sub-node:
+
+ The cs35l35 node can have a single "cirrus,monitor-signal-format" sub-node
+ for adjusting the Depth, Location and Frame of the Monitoring Signals
+ for Algorithms.
+
+ See Sections 4.8.2 through 4.8.4 Serial-Port Control in the Datasheet
+
+ -cirrus,monitor-signal-format : Sub-node for the Monitor Signaling Formating
+ on the I2S Port. Each of the 3 8 bit values in the array contain the settings
+ for depth, location, and frame.
+
+ If not used, the defaults for the 6 monitor signals is used.
+
+ Sections 7.44 - 7.53 lists values for the depth, location, and frame
+ for each monitoring signal.
+
+ - cirrus,imon : 3 8 bit values to set the depth, location, and frame
+ of the IMON monitor signal.
+
+ - cirrus,vmon : 3 8 bit values to set the depth, location, and frame
+ of the VMON monitor signal.
+
+ - cirrus,vpmon : 3 8 bit values to set the depth, location, and frame
+ of the VPMON monitor signal.
+
+ - cirrus,vbstmon : 3 8 bit values to set the depth, location, and frame
+ of the VBSTMON monitor signal
+
+ - cirrus,vpbrstat : 3 8 bit values to set the depth, location, and frame
+ of the VPBRSTAT monitor signal
+
+ - cirrus,zerofill : 3 8 bit values to set the depth, location, and frame\

Read the spec. "timer" is a generic node name. "timers" is not. How
many is not relevant.

The "extremity_freq" frequency described in the original FEX files uses
a voltage of 1.46v, which is beyond the current maximum voltage value of
DCDC2 (Cortex-A7 supply) in the sun8i reference tablet DTSI file.
Raise the maximum value to 1.46v.

An operating point table is needed for the cpu frequency adjusting to
work.
The operating point table is converted from the common value in
extracted script.fex from many A33 board/tablets.
1.344GHz is set as a turbo-mode operating point, as it's described as
"extremity_freq" in the FEX file. (the "max_freq" is 1.2GHz)
