Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui:
"There are not too many changes this time, except two new platform
thermal drivers, ti-soc-thermal driver and x86_pkg_temp_thermal
driver, and a couple of small fixes.
Highlights:
- move the ti-soc-thermal driver out of the staging tree to the
thermal tree.
- introduce the x86_pkg_temp_thermal driver. This driver registers
CPU digital temperature package level sensor as a thermal zone.
- small fixes/cleanups including removing redundant use of
platform_set_drvdata() and of_match_ptr for all platform thermal
drivers"

1 | * Texas Instrument OMAP SCM bandgap bindings | ||
2 | |||
3 | In the System Control Module, OMAP supplies a voltage reference | ||
4 | and a temperature sensor feature that are gathered in the band | ||
5 | gap voltage and temperature sensor (VBGAPTS) module. The band | ||
6 | gap provides current and voltage reference for its internal | ||
7 | circuits and other analog IP blocks. The analog-to-digital | ||
8 | converter (ADC) produces an output value that is proportional | ||
9 | to the silicon temperature. | ||
10 | |||
11 | Required properties: | ||
12 | - compatible : Should be: | ||
13 | - "ti,omap4430-bandgap" : for OMAP4430 bandgap | ||
14 | - "ti,omap4460-bandgap" : for OMAP4460 bandgap | ||
15 | - "ti,omap4470-bandgap" : for OMAP4470 bandgap | ||
16 | - "ti,omap5430-bandgap" : for OMAP5430 bandgap | ||
17 | - interrupts : this entry should indicate which interrupt line | ||
18 | the talert signal is routed to; | ||
19 | Specific: | ||
20 | - gpios : this entry should be used to inform which GPIO | ||
21 | line the tshut signal is routed to. The informed GPIO will | ||
22 | be treated as an IRQ; | ||
23 | - regs : this entry must also be specified and it is specific | ||
24 | to each bandgap version, because the mapping may change from | ||
25 | soc to soc, apart of depending on available features. | ||
26 | |||
27 | Example: | ||
28 | OMAP4430: | ||
29 | bandgap { | ||
