imx: thermal: use CPU temperature grade info for thresholds

2015-11-24T00:38:40+00:00

The IMX6Q/IMX6DL SoC's have a 2-bit temperature grade stored in OTP which
is valid for all IMX6 SoC's (despite the fact that the IMXSDLRM and
IMXSXRM do not document this - this has been proven via tests as well as
verified by Freescale FAE).

Instead of assuming a fixed 85C for passive cooling threshold and 105C for
critical use the thermal grade for these configurations.

We will set the critical to maxT - 5C and passive to maxT - 10C.

v3:
 - rebase against linux-soc-thermal.git
 - added ack's from Shawn and Jon
v2:
 - remove check for IMX6Q and update comments: The OTP values have been tested
   on IMX6SOLO, IMX6DUALLITE, and IMX6SX and Freescale FAE has shared data with
   me that the OTP settings are the same and that the reference manuals will
   reflect this in their next updates.
 - set critical to max - 5C
 - set passive to max - 10C
 - display max temp in info
 - do not allow passive to be set above critical

Revert "thermal: qcom_spmi: allow compile test"

2015-11-23T23:33:56+00:00

This just caused build errors:

warning: (QCOM_SPMI_TEMP_ALARM) selects REGMAP_SPMI which has unmet direct dependencies (SPMI)
drivers/built-in.o: In function `regmap_spmi_ext_gather_write':
:(.text+0x609b0): undefined reference to `spmi_ext_register_write'
:(.text+0x609f0): undefined reference to `spmi_ext_register_writel'

While it's generally a good idea to allow compile testing, in this
case, it just doesn't work, so reverting the patch that
introduced the compile-test variant seems the most appropriate
solution.

Note that SPMI also has a 'depends on ARCH_QCOM || COMPILE_TEST'
statement, so we should be able to enable SPMI on all architectures
for compile testing already.

Probe error operation and remove operation are same.
Let's use same function.

thermal: of-thermal: Reduce log level for message when can't fine thermal zone

2015-11-16T18:49:17+00:00

Some systems register thermal zone by themself and don't need to
have thermal zones node in DT. Therefore reduce the log level from
ERROR to DEBUG when thermal zone node can't be find in
of_thermal_destroy_zones().

thermal: power_allocator: Use temperature reading from tz

2015-11-12T18:47:24+00:00

All thermal governors use the temperature value stored in
struct thermal_zone_device.

   thermal_zone_device->temperature

power_allocator governor should not deviate from this and use
the same.

thermal: rockchip: Support the RK3368 SoCs in thermal driver

2015-11-12T18:21:30+00:00

The RK3368 SoCs support to 2 channel TS-ADC, the temperature criteria
of each channel can be configurable.

The system has two Temperature Sensors, channel 0 is for CPU,
and channel 1 is for GPU.

thermal: rockchip: consistently use int for temperatures

2015-11-12T18:20:16+00:00

As Temperature is currently represented as int not long in the thermal
framework since use int intead of unsigned long/long to represent
temperature to avoid bogus overheat detection when negative temperature
reported.

thermal: rockchip: Add the sort mode for adc value increment or decrement

2015-11-12T18:19:09+00:00

The conversion table has the adc value and temperature.
In fact, the adc value only has the increment or decrement mode in
conversion table.

Moment, we can add the sort mode to be better support the *code_to_temp*
for differenr SoCs.

thermal: rockchip: improve the conversion function

2015-11-12T18:17:35+00:00

We should make the conversion table in as a parameter since the different
SoCs have the different conversionion table.
