thermal: qoriq: Fix a compiling issue

2020-04-23T08:38:20+00:00

[ Upstream commit cbe259fd80b7b02fba0dad79d8fdda8b70a8b963 ]

Qoriq thermal driver is used by both PowerPC and ARM architecture.
When built for PowerPC architecture, it reports error:
undefined reference to `.__devm_regmap_init_mmio_clk'
To fix it, select config REGMAP_MMIO.

thermal/drivers/cpufreq_cooling: Fix return of cpufreq_set_cur_state

2020-04-23T08:38:09+00:00

[ Upstream commit ff44f672d74178b3be19d41a169b98b3e391d4ce ]

When setting the cooling device current state from userspace via sysfs,
the operation fails by returning an -EINVAL.

It appears the recent changes with the per-policy frequency QoS
introduced a regression as reported by:

 https://lkml.org/lkml/2020/3/20/599

The function freq_qos_update_request returns 0 or 1 describing update
effectiveness, and a negative error code on failure. However,
cpufreq_set_cur_state returns 0 on success or an error code otherwise.

Consider the QoS update as successful if the function does not return
an error.

drivers: thermal: tsens: Release device in success path

2020-04-23T08:38:08+00:00

[ Upstream commit f22a3bf0d2225fba438c46a25d3ab8823585a5e0 ]

We don't currently call put_device in case of successfully initialising
the device. So we hold the reference and keep the device pinned forever.

Allow control to fall through so we can use same code for success and
error paths to put_device.

As a part of this fixup, change devm_ioremap_resource to act on the same
device pointer as that used to allocate regmap memory. That ensures that
we are free to release op->dev after examining its resources.

thermal: int340x_thermal: fix: Update Tiger Lake ACPI device IDs

2020-04-17T14:13:27+00:00

commit 26d8bec1e97ba218b7d82afadca1c049eb75f773 upstream.

Tiger Lake's new unique ACPI device IDs for Intel thermal driver are not
valid because of missing 'C' in the IDs. Fix the IDs by updating them.

After the update, the new IDs should now look like
INT1040 --> INTC1040
INT1043 --> INTC1043

thermal: intel_pch: switch to use helpers

2020-01-31T18:30:40+00:00

This switches the intel pch thermal driver to use
deci_kelvin_to_millicelsius() in  instead of helpers in
.

This is preparation for centralizing the kelvin to/from Celsius
conversion helpers in .
