thermal, cpufreq: Fix build when CPU_FREQ_TABLE isn't configured

2012-10-15T21:00:07+00:00

Commit 023614183768 ("thermal: add generic cpufreq cooling
implementation") requires cpufreq_frequency_get_table(), but that
function is only defined for CONFIG_CPU_FREQ_TABLE resulting in the
following build error:

  drivers/built-in.o: In function `cpufreq_get_max_state':
  drivers/thermal/cpu_cooling.c:259: undefined reference to `cpufreq_frequency_get_table'
  drivers/built-in.o: In function `get_cpu_frequency':
  drivers/thermal/cpu_cooling.c:129: undefined reference to `cpufreq_frequency_get_table'

Fix it by selecting CONFIG_CPU_FREQ_TABLE for such a configuration.

It turns out CONFIG_EXYNOS_THERMAL also needs CONFIG_CPU_FREQ_TABLE, so
select it there as well.

idr: rename MAX_LEVEL to MAX_IDR_LEVEL

2012-10-05T18:04:56+00:00

To avoid name conflicts:

  drivers/video/riva/fbdev.c:281:9: sparse: preprocessor token MAX_LEVEL redefined

While at it, also make the other names more consistent and add
parentheses.

thermal: Exynos: Fix NULL pointer dereference in exynos_unregister_thermal()

2012-09-28T00:23:21+00:00

exynos_unregister_thermal() is functional only when 'th_zone' is not
NULL (ensured by the NULL checks). However, in the event it is NULL, it
gets dereferenced in the for loop. This patch fixes this issue.

Thermal: Fix bug on cpu_cooling, cooling device's id conflict problem.

2012-09-27T06:11:22+00:00

This patch fixes small bug on cpu_cooling. CPU cooling device has own
id generated with idr mathod. However in the previous version, it swapped
to all same id at last stage of probing as 0. This makes id's collision and
also occures error when it releases that id.

thermal: exynos: Use devm_* functions

2012-09-24T06:44:38+00:00

devm_* functions are used to replace kzalloc, request_mem_region, ioremap
and request_irq functions in probe call. With the usage of devm_* functions
explicit freeing and unmapping is not required.

ARM: exynos: add thermal sensor driver platform data support

2012-09-24T06:44:38+00:00

Add necessary default platform data support needed for TMU driver.  The
supplied dt/non-dt values are tested for origen exynos4210 and smdk exynos5250
platforms and only compile tested for exynos4412.

thermal: exynos: register the tmu sensor with the kernel thermal layer

2012-09-24T06:44:38+00:00

This code added creates a link between temperature sensors, linux thermal
framework and cooling devices for samsung exynos platform.  This layer
monitors the temperature from the sensor and informs the generic thermal
layer to take the necessary cooling action.

Insert exynos5 TMU sensor changes into the thermal driver.  Some exynos4
changes are made generic for exynos series.

hwmon: exynos4: move thermal sensor driver to driver/thermal directory

2012-09-24T06:44:38+00:00

This movement is needed because the hwmon entries and corresponding sysfs
interface is a duplicate of utilities already provided by
driver/thermal/thermal_sys.c.  The goal is to place it in thermal folder
and add necessary functions to use the in-kernel thermal interfaces.
