When resource is powered off, getting temperature from SCU firmware will fail,
and it will keep printing out error message which is NOT making sense, fix it
by printing the failure once and return temperature 0 for the powered-off resource.[ 1818.342337] thermal thermal_zone0: failed to read out thermal zone (-1)

It makes more sense to trigger system-wide device cooling for
all thermal zones rather than thermal zone0 ONLY.Signed-off-by: Anson Huang

Register device cooling for each thermal zone manually, when
temperature exceeds passive trip, system wide cooling notification
will be triggered.Signed-off-by: Anson Huang

Pull thermal updates from Daniel Lezcano:
- Add the hwmon support on the i.MX SC (Anson Huang)
- Thermal framework cleanups (self-encapsulation, pointless stubs,
private structures) (Daniel Lezcano)- Use the PM QoS frequency changes for the devfreq cooling device
(Matthias Kaehlcke)- Remove duplicate error messages from platform_get_irq() error
handling (Markus Elfring)- Add support for the bandgap sensors (Keerthy)
- Statically initialize .get_mode/.set_mode ops (Andrzej Pietrasiewicz)
- Add Renesas R-Car maintainer entry (Niklas Söderlund)
- Fix error checking after calling ti_bandgap_get_sensor_data() for the
TI SoC thermal (Sudip Mukherjee)- Add latency constraint for the idle injection, the DT binding and the
change the registering function (Daniel Lezcano)- Convert the thermal framework binding to the Yaml schema (Amit
Kucheria)- Replace zero-length array with flexible-array on i.MX 8MM (Gustavo A.
R. Silva)- Thermal framework cleanups (alphabetic order for heads, replace
module.h by export.h, make file naming consistent) (Amit Kucheria)- Merge tsens-common into the tsens driver (Amit Kucheria)
- Fix platform dependency for the Qoriq driver (Geert Uytterhoeven)
- Clean up the rcar_thermal_update_temp() function in the rcar thermal
driver (Niklas Söderlund)- Fix the TMSAR register for the TMUv2 on the Qoriq platform (Yuantian
Tang)- Export GDDV, OEM vendor variables, and don't require IDSP for the
int340x thermal driver - trivial conflicts fixed (Matthew Garrett)* tag 'thermal-v5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thermal/linux: (48 commits)

i.MX8 SoCs DTS file needs system control macro definitions, so move them
into dt-binding headfile, then include/linux/firmware/imx/types.h can be
removed and those drivers using it should be changed accordingly.Signed-off-by: Dong Aisheng

use __packed __aligned(4) to avoid potential oopses.Signed-off-by: Anson Huang

i.MX8QXP is an ARMv8 SoC which has a Cortex-M4 system controller
inside, the system controller is in charge of controlling power,
clock and thermal sensors etc..This patch adds i.MX system controller thermal driver support,
Linux kernel has to communicate with system controller via MU
(message unit) IPC to get each thermal sensor's temperature,
it supports multiple sensors which are passed from device tree,
please see the binding doc for details.Signed-off-by: Anson Huang
