[PATCH 0/8] arm64: dts: qcom: Add SA8155p-adp board DTS

[Bhupesh Sharma]

This series adds DTS for SA8155p-adp board which is based on
Qualcomm snapdragon sm8150 SoC. 

This patchset also includes DTS for the two new PMICs PMM8155AU_1
and PMM8155AU_2 found on the adp board.

Looking at the component documentation and the schematics I think the
component is "PMM8155AU" and we have two of them.

Unless I'm mistaken we should have the compatible describe the single
component and we should have DT describe the fact that we have 2 of
them.

Bjorn

If we refer to the PM8155AU device specifications, there are two
regulators mentioned there PMM8155AU_1 and PMM8155AU_2. Although most
parameters of the regulators seem similar the smps regulator summary
for both appear different (Transient Load, mA ratings etc).

Although most of these differences don't probably matter to the Linux
world, others like the gpios on the pmic are different.

So, IMO, it makes sense to mention the different pmic types on the board.

Please let me know your views on the same.

Thanks,
Bhupesh

Afaict, they are both physically the same component, but there is some
configuration differences between them. I don't see any differences that
will show up in Linux, but afaict we would capture those in the DT
anyways.

Let me know if you see anything I'm missing, but I think we should have
a single compatible.

As discussed on IRC, let's go with the approach you suggested (I can
propose followup patches if I find something amiss). I will send a v2

As with the regulator this seems to be a single component.

In the schematics all 10 pins are wired on both of these PMICs, so I
don't think there are holes. Please omit the comment.

But if we look at the downstream dts (see [1]), we clearly have holes
on gpio 2, 5 and 7 on PMM8155AU_2 whereas if we see [2], we can see
PMM8155AU_1 has holes on gpio 2, 5, 7 and 8.

As I understand, the schematics mention some optional configurations
as well which might not be available depending on the default board
configuration.

Perhaps these "holes" means that they are reserved for use by one of the
other subsystems in the SoC - similar to how we have
gpio-reserved-ranges in the TLMM. Because according to the PMS8155AU
documentation and the schematics, there's no physical holes there.

As such, the binding and driver should not describe these "holes". If
they aren't used by Linux, then the DT won't reference them - and if
there's reasons for prohibiting Linux from touching the registers we
should use gpio-reserved-ranges, as this will depend on firmware
configuration.

[PATCH 3/8] dt-bindings: arm: qcom: Add compatible for SA8155p-adp board

[Bhupesh Sharma]

SA8155p-adp board is based on Qualcomm Snapdragon sm8150
SoC.

Add support for the same.

The SA8155p is similar to SM8150 and we can reuse most things, but I
think we can afford to add qcom,sa8155p in the DT bindings.

Naturally sm8150 should be part of this list, but please also add
sa8155p as well.

And please split this in two (one qcom,sm8150-mtp and qcom,sm8150, and
one qcom,sa8155p-adp and qcom,sa8155p).

And note that this is saying that your compatible needs to be one of the
enum entries, followed by the const, but in your dts you only specified
qcom,sa8155p-adp. It needs to be:

	compatible = "qcom,sa8155p-adp", "qcom,sa8155p";

Thanks,
Bjorn

[PATCH 4/8] regulator: qcom-rpmh: Add new regulator types found on SA8155p adp board

[Bhupesh Sharma]

SA8155p-adp board has two new regulator types - pmm8155au_1 and
pmm8155au_2.

The output power management circuits in these regulators include:
- FTS510 smps,
- HFS510 smps, and
- LDO510 linear regulators

It's just a matter of preference IMO. I prefer to use a Cc list
here.

Hmm.. it's similar to the syntax already used at several places in this file.
See ' struct rpmh_vreg_init_data pm8150l_vreg_data[] ' for example.

Unless there is an obvious issue with it, let's use the same to keep
things similar from a syntax p-o-v.

The Cc list in the commit message will be committed to the git history
and there it carries the information that you specifically made sure
that these people saw the patch. So please limit the use to that
purpose.

Those other places shouldn't use the ',' either, so please help set a
better precedence.

I understand, but different maintainers like different formats here.
Infact, there
are suggestions not to use --cc as some opens-source lists are known to drop
folks from Cc list accidentally (mentioned via --cc) , so some folks
prefer the git log to contain the Cc list instead.

But I can trim the same for v2.

Sure, I will send that out as a separate clean-up patch.

[PATCH 5/8] pinctrl: qcom/pinctrl-spmi-gpio: Add compatibles for pmic-gpios on SA8155p-adp

[Bhupesh Sharma]

SA8155p-adp PMICs (PMM8155AU_1 and PMM8155AU_2) expose
the following PMIC GPIO blocks:

- PMM8155AU_1: gpio1-gpio10 (with holes on gpio2, gpio5, gpio7 and gpio8)
- PMM8155AU_2: gpio1-gpio10 (with holes on gpio2, gpio5, gpio7)

Add support for the same in the pinctrl driver.

As noted in the binding, I think this should be "qcom,pmm8155au-gpio"
and please skip the comment about the holes.

Similar to what I noted in the binding patch review thread, the pmic
gpio holes seem different as per the downstream dtsi.

So, please let me know and if required, I can make the suggested change in v2.

As noted in the binding, this really seems like software configuration.
So we should deal with this in DT (e.g. by not referencing the gpios
that Linux shouldn't touch), rather than the driver.

As we describe our PMICs by including their definition to the top level
of the .dts I don't see any alternative to duplicating this as _1 and
_2. So let's go with this structure.

I don't think you need to give this a label.

This is a "qcom,pmm8155au", "qcom,spmi-pmic", the labels are used to
differentiate the two instances.

[PATCH 8/8] arm64: dts: qcom: sa8155p-adp: Add base dts file

[Bhupesh Sharma]

Add base DTS file for sa8155p-adp and enable boot to console,
tlmm reserved range and also include pmic file(s).

SA8155p-adp board is based on sm8150 Qualcomm Snapdragon SoC.

I didnt find these labels very useful, so maybe remove?
It helped me to understand that a regulator is vreg_l5a_0p88 as it
implies I am using l5a with 0p88V :)

Pls do add regulator-name property, it helps in understanding which ldo
in logs/debugfs, otherwise ldo5 will comes for both pmics

Oops, missed that. Will fix it in v2.

Oh, ok, I thought of keeping all boards based on sm8150 SoC together.
But alphabetically, it makes more sense to put it earlier.

While a few labels like 'vdd_usb_hs_core' are used in this patch (for
example) to denote 'vdda-pll-supply ' of 'usb_1_hsphy', the others
would be required as we enable further on-boards peripherals in the
dts.

I will recheck and limit these further in v2.

That's a good point. Will fix this in v2.

Please spell out "sa8155-adp", i.e. "Add base DTS for SA8155p Automotive
Development Platform."

It's not based on sm8150, it's based on sa8155p, so let's express this
as "The SA8155p platform is similar to the SM8150, so use this as base
for now", to document why we decided to do this.

This would go into the git history as "I specifically asked for input
from these people", so please keep this list shorter (but for a change
like this it's probably better to omit it completely)

You can reduce this to

This is the "label" of the pad which the regulator typically is
connected to (rather than a denotion of which regulator it is). So even
though we have these in some of the other boards, I would prefer if you
skip them and only use the vreg_xyz_abc variant.

We have enough pieces to handle mode switching on this platform, but as
discussed, lets leave it as "peripheral" until your local setup is back
online.

Ok, I wanted to keep it similar to the comment we have for sm815o-mtp,
but this is fine as well.

Lets keep the 'vdd_xx_abc labels' though which are used as input
supply pads for peripherals, for e.g.:

&usb_1_hsphy {
    status = "okay";
    vdda-pll-supply = <&vdd_usb_hs_core>;
    vdda33-supply = <&vdda_usb_hs_3p1>;
    vdda18-supply = <&vdda_usb_hs_1p8>;
};

IMO, here it makes sense to retain labels 'vdda_usb_hs_3p1' and
'vdda_usb_hs_1p8' in the dts (also making it easier to trace the same
in schematics).

I will send the v2 with the other suggested changes shortly.
