-Subject: [PATCH] thermal/drivers/sun8i: Don't fail probe due to zone
- registration failure
-
-Currently the sun8i thermal driver will fail to probe if any of the
-thermal zones it is registering fails to register with the thermal core.
-Since we currently do not define any trip points for the GPU thermal
-zones on at least A64 or H5 this means that we have no thermal support
-on these platforms:
-
-[ 1.698703] thermal_sys: Failed to find 'trips' node
-[ 1.698707] thermal_sys: Failed to find trip points for thermal-sensor id=1
-
-even though the main CPU thermal zone on both SoCs is fully configured.
-This does not seem ideal, while we may not be able to use all the zones
-it seems better to have those zones which are usable be operational.
-Instead just carry on registering zones if we get any non-deferral
-error, allowing use of those zones which are usable.
-
-This means that we also need to update the interrupt handler to not
-attempt to notify the core for events on zones which we have not
-registered, I didn't see an ability to mask individual interrupts and
-I would expect that interrupts would still be indicated in the ISR even
-if they were masked.
