[ Upstream commit fc7d18cf6a923cde7f5e7ba2c1105bb106d3e29a ] We print a calibration failure message on -EPROBE_DEFER from nvmem/qfprom as follows: [ 3.003090] qcom-tsens 4a9000.thermal-sensor: version: 1.4 [ 3.005376] qcom-tsens 4a9000.thermal-sensor: tsens calibration failed [ 3.113248] qcom-tsens 4a9000.thermal-sensor: version: 1.4 This confuses people when, in fact, calibration succeeds later when nvmem/qfprom device is available. Don't print this message on a -EPROBE_DEFER.

[ Upstream commit 129699bb8c7572106b5bbb2407c2daee4727ccad ] Changes since V1: * Use dev_info instead of printk * Use dev_warn instead of BUG_ON Previously, sysfs_create_group was called before all initialization had fully run - specifically, before pci_set_drvdata was called. Since the sysctl group is visible to userspace as soon as sysfs_create_group returns, a small window of time existed during which a process could read from an uninitialized/partially-initialized device. This commit moves the creation of the sysctl group to after all initialized is completed. This ensures that it's impossible for userspace to read from a sysctl file before initialization has fully completed. To catch any future regressions, I've added a check to ensure that proc_thermal_emum_mode is never PROC_THERMAL_NONE when a process tries to read from a sysctl file. Previously, the aforementioned race condition could result in the 'else' branch running while PROC_THERMAL_NONE was set, leading to a null pointer deference.

[ Upstream commit 9d216211fded20fff301d0317af3238d8383634c ] First correct the edge case to return the last element if we're outside the range, rather than at the last element, so that interpolation is not omitted for points between the two last entries in the table. Then correct the formula to perform linear interpolation based the two points surrounding the read ADC value. The indices for temp are kept as "hi" and "lo" to pair with the adc indices, but there's no requirement that the temperature is provided in descendent order. mult_frac() is used to prevent issues with overflowing the int.

[ Upstream commit 964f4843a455d2ffb199512b08be8d5f077c4cac ]
commit ff140fea847e ("Thermal: handle thermal zone device properly
during system sleep") added PM hook to call thermal zone reset during
sleep. However resetting thermal zone will also clear the passive state
and thus cancel the polling queue which leads the passive cooling device
state not being cleared properly after sleep.
thermal_pm_notify => thermal_zone_device_reset set passive to 0
thermal_zone_trip_update will skip update passive as `old_target ==
instance->target'.
monitor_thermal_zone => thermal_zone_device_set_polling will cancel
tz->poll_queue, so the cooling device state will not be changed
afterwards.

[ Upstream commit 152395fd03d4ce1e535a75cdbf58105e50587611 ] When thermal zone is in passive mode, disabling its mode from sysfs is NOT taking effect at all, it is still polling the temperature of the disabled thermal zone and handling all thermal trips, it makes user confused. The disabling operation should disable the thermal zone behavior completely, for both active and passive mode, this patch clears the passive_delay when thermal zone is disabled and restores it when it is enabled.
