Hi Vasily,

For this entire series, the DTS files don't contain any trip points.
Did I miss some other series?

At a minimum, you should add some "hot" or "critical" trip points
since then don't require a cooling-map with throttling actions. If you
have "passive" trip points, then you need to provide cooling-maps.

Except I'm misunderstanding the bindings, a thermal zone must define
these required properties:

- polling-delay
- polling-delay-passive
- thermal-sensors
- trips
- cooling-maps

Right, except for the cooling-maps. Those are exempted if there is the
trip type is not passive. That is my understanding of the existing
bindings.

Trip type critical triggers a shutdown and trip type hot only triggers
a notification - see thermal_core.c:handle_critical_trips(). So we
only need cooling maps for passive trip types.

Since this series has been merged, could you please follow up with a
fixup series to add the trip points?

Regards,
Amit
p.s. We should catch all this automatically, I'll send out yaml
bindings for the thermal framework soon that should catch this stuff.

There was a small discussion about converting the binding to a schema:

https://www.spinics.net/lists/devicetree/msg332424.html

Aah, I missed that. I started working on something last week that
looks similar to your discussion. Pushed a WIP branch here[1], it
looks like I had a similar idea on how to split the bindings. Hope to
finish this up tomorrow for an RFC.

Regards,
Amit

This patchset adds driver for thermal sensor in A64, A83T, H3, H5,
H6 and R40 SoCs.

v8:
        - [vasily] Address more Maxime's comments for dt-schema
        - [vasily] Add myself to MAINTAINERS for the driver and schema
        - [vasily] Round calibration data size to word boundary for H6 and A64
        - [vasily] Change offset for A64 since it reports too low temp otherwise.
                   Likely conversion formula in user manual is not correct.

v7:
        - [vasily] Address Maxime's comments for dt-schema
        - [vasily] Move common part of H3 and H5 dts into sunxi-h3-h5.dtsi
        - [vasily] Add Maxime's a-b to the driver patch

v6:
        - [ondrej, vasily] Squash all driver related changes into a
                           single patch
        - [ondrej] Rename calib -> calibration
        - [ondrej] Fix thermal zone registration check
        - [ondrej] Lower rate of sensor data interrupts to 4/sec/sensor
        - [ondrej] Rework scale/offset values, H6 calibration
        - [ondrej] Explicitly set mod clock to 24 MHz
        - [ondrej] Set undocumented bits in CTRL0 for H6
        - [ondrej] Add support for A83T
        - [ondrej] Add dts changes for A83T, H3, H5, H6
        - [vasily] Add dts changes for A64
        - [vasily] Address Maxime's comments for YAML scheme
        - [vasily] Make .calc_temp callback mandatory
        - [vasily] Set .max_register in regmap config, so regs can be
                   inspected using debugfs
