thermal: int340x_thermal: Ignore missing _ART, _TRT tables

2015-02-28T05:58:36+00:00

It is possible that _ART/_TRT tables are missing or have errors.
Ignore those failures, as INT3400 thermal zone is still required
for _OSC or mode switch.

thermal/intel_powerclamp: add id for Avoton SoC

2015-02-28T05:55:40+00:00

Enable Intel Powerclamp driver on Atom* Processor C2000 Product
Family for Microservers (Avoton). Avoton - SoCs for micro-servers
has package C-states which can be used for idle injection.

thermal: rcar: Make error and remove paths symmetrical with init

2015-02-24T18:58:05+00:00

Swap interrupt disable and thermal zone unregistration in the error and
remove paths, to make them more symmetrical with the initialization
path.

thermal: rcar: Fix race condition between init and interrupt

2015-02-24T18:56:42+00:00

As soon as the interrupt has been enabled by devm_request_irq(), the
interrupt routine may be called, depending on the current status of the
hardware.

However, at that point rcar_thermal_common hasn't been initialized
complely yet. E.g. rcar_thermal_common.base is still NULL, causing a
NULL pointer dereference:

    Unable to handle kernel NULL pointer dereference at virtual address 0000000c
    pgd = c0004000
    [0000000c] *pgd=00000000
    Internal error: Oops: 5 [#1] SMP ARM

    PC is at rcar_thermal_irq+0x1c/0xf0

Postpone the call to devm_request_irq() until all initialization has
been done to fix this.

ti-soc-thermal: Delete an unnecessary check before the function call "cpufreq_cooling_unregister"

2015-02-24T18:26:56+00:00

The cpufreq_cooling_unregister() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

thermal: exynos: fix: Check if data->tmu_read callback is present before read

2015-02-20T13:57:02+00:00

The exynos_tmu_data() function should on entrance test not only for valid
data pointer, but also for data->tmu_read one.
It is important, since afterwards it is dereferenced to get temperature code.

Pull more thermal managament updates from Zhang Rui:
"Specifics:

- Exynos thermal driver refactoring. Several cleanups, code
optimization, unused symbols removal, and unused feature removal in
Exynos thermal driver. Thanks Lukasz for this effort.

- Exynos thermal driver support to OF thermal. After the code
refactoring, the driver earned the support to OF thermal. Chip
thermal data were moved from driver code to DTS, reducing the code
footprint. Thanks Lukasz for this.

- After receiving the OF thermal support, the exynos thermal driver
now must allow modular build. Thanks Arnd for detecting, reporting
and fixing this.

- Exynos thermal driver support to Exynos 7 SoC. Thanks Abhilash for
this.

- Accurate temperature reporting on Rockchip thermal driver, thanks
to Caesar.

- Fix on how OF thermal enables its zones, thanks Lukasz for fixing.

- Fixes in OF thermal examples under Documentation/. Thanks Srinivas
for fixing"
