docs: thermal: convert to ReST
Rename the thermal documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

User can set temperature -manually with software code and TMU will read current temperature from user value not from -sensor's value. - -Enabling CONFIG_THERMAL_EMULATION option will make this support available. -When it's enabled, sysfs node will be created as -/sys/devices/virtual/thermal/thermal_zone'zone id'/emul_temp. - -The sysfs node, 'emul_node', will contain value 0 for the initial state. When you input any -temperature you want to update to sysfs node, it automatically enable emulation mode and -current temperature will be changed into it. -(Exynos also supports user changeable delay time which would be used to delay of - changing temperature. However, this node only uses same delay of real sensing time, 938us.) - -Exynos emulation mode requires synchronous of value changing and enabling. It means when you -want to update the any value of delay or next temperature, then you have to enable emulation -mode at the same time. (Or you have to keep the mode enabling.) If you don't, it fails to -change the value to updated one and just use last succeessful value repeatedly. That's why -this node gives users the right to change termerpature only. Just one interface makes it more -simply to use. - -Disabling emulation mode only requires writing value 0 to sysfs node. - - -TEMP 120 | - | - 100 | - | - 80 | - | +----------- - 60 | | | - | +-------------| | - 40 | | | | - | | | | - 20 | | | +---------- - | | | | | - 0 |______________|_____________|__________|__________|_________ - A A A A TIME - |<----->| |<----->| |<----->| | - | 938us | | | | | | -emulation : 0 50 | 70 | 20 | 0 -current temp : sensor 50 70 20 sensor |
