[RESEND PATCH V3 0/5] Add PMIC DT files for sc7280

[RESEND PATCH V3 0/5] Add PMIC DT files for sc7280

[satya priya]

Hi All,

Resending V3 as there was a mistake earlier, changes in patches 4 and 5
got clubbed unknowingly. Apologies for that.

Thanks,
Satya Priya

Add PM7325 DT file with gpio and temp-alarm nodes.
For PM8350C, PMR735A and PMK8350 add the required peripherals
as the base DT files are already added [1].
[1] https://lore.kernel.org/patchwork/project/lkml/list/?series=489011&state=%2A&archive=both

Changes in V2:
 - As per Matthias comments:
   - I've Split the patch into per-PMIC patches and one sc7280 patch
   - Removed 2nd critical point, thermal-governer property
   - s/pm8325_tz/pm7325_temp_alarm and s/pm7325_temp_alarm/pm7325_thermal
   - Fixed few other minor errors.

 - As per Bjorn's comments, replaced '_' with '-' in node names and moved
   DT files inclusion to board dts.

Changes in V3:
 - As per Matthias comments, changed commit text, modified critical interrupt
   node name like <name>-crit for all pmics.
 - Moved pmk8350_vadc channel nodes to idp dts, as it is not guaranteed that
   a board with the pmk8350 will always have the other 3 PMICs

nit: why 'PMIC peripherals', are these peripherals somehow specific
to PMICs?

nit: it seems somewhat arbitrary to specifically mention PON and RTC,
and then treat the ADC and the thermal monitor as 'others'. You could
just spell them out too.

the includes of the constants for the other PMICs seems to be an
remainder from older vesions, which included nodes for the on die
temperatures of these PMICs.

Please make sure to distinguish between the SoC (sc7280) and the
board (sc7280-idp), this patch primarily adds stuff to the board not
the SoC, this should be clear from the subject.

> Include pm7325, pm8350c, pmk8350 and pmr735a DT files.

How about something like 'The sc7280-idp has four PMICs, include their
.dtsi files'?

> Add channel nodes for pmk8350_vadc.

It's not super important, but I don't like it when things like this get
sneaked in with a commit message saying 'Include PMIC DT files for
sc7280'. I would suggest a separate patch. And please mention that
the channels are for the on die temperatures of the PMICs.

> Also, add the thermal_zones node in dtsi.

This is not the right patch to add it. This patch is about the sc7280-board
and doesn't do anything (directly) with thermal zones. However other
patches further down in the stack of in this series require the
'thermal-zones' to exist, hence the node should exist before these patches
reference it. A dedicated patch adding the node seems like the best option
to me.

Okay will change it.

As I have added on die temp nodes for these pmics in sc7280-idp file, 
will add these header files also there.
