2016-09-27thermal: tegra: add hw-throttle for Tegra132Wei Ni2-30/+221
Tegra132 use CCROC throttle registers to configure pulse skiper, set these registers to enable throttle function for Tegra132. Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
2016-09-27thermal: tegra: add hw-throttle functionWei Ni5-15/+700
Tegra soctherm support HW throttle, when the soctherm snesors' temperature is above the throttle trip point, it will trigger pulse skiper to tune clocks accroding to the throttle depth. Add this function for Tegra124 and Tegra210. Since Tegra132 use different registers to configure pulse skiper, will support it in next patch.

2016-05-17thermal: tegra: fix static checker warningWei Ni1-4/+1
There has a static checker warning: warn: variable dereferenced before check 'dev' (see line 222) Since check 'dev' is unnecessary, so remove this check.

2016-05-17thermal: tegra: mark PM functions __maybe_unusedArnd Bergmann1-2/+2
After the PM support has been added to this driver, we get a harmless warning when that support is disabled at compile time: drivers/thermal/tegra/soctherm.c:641:12: error: 'soctherm_resume' defined but not used [-Werror=unused-function] static int soctherm_resume(struct device *dev) This marks the two PM functions as __maybe_unused to shut up the warning. This is preferred over adding an #ifdef around them, as it is harder to get wrong, and provides better compile-time coverage.

2016-05-17thermal: tegra: add thermtrip functionWei Ni4-5/+216
Add support for hardware critical thermal limits to the SOC_THERM driver. It use the Linux thermal framework to create critical trip temp, and set it to SOC_THERM hardware. If these limits are breached, the chip will reset, and if appropriately configured, will turn off the PMIC. This support is critical for safe usage of the chip.

2016-05-17thermal: tegra: split tegra_soctherm driverWei Ni7-566/+754
Split most of the Tegra124 data and code into a Tegra124-specific file. Split most of the fuse-related code into a fuse-related source file. This is in preparation for adding a Tegra210-specific driver in a future patch. Beyond the maintainability improvements, this is intended to separate chip-specific ATE and characterization-related hacks into chip-specific files, in the hopes that they won't pollute code for other chips.

2016-05-17thermal: tegra: get rid of PDIV/HOTSPOT hackWei Ni1-4/+15
Get rid of T124-specific PDIV/HOTSPOT hack. tegra-soctherm.c contained a hack to set the SENSOR_PDIV and SENSOR_HOTSPOT_OFFSET registers - it just did two writes of T124-specific opaque values. Convert these into a form that can be substituted on a per-chip basis, and into structure fields that have at least some independent meaning.

2016-05-17thermal: tegra: combine sensor group-related dataWei Ni1-27/+118
Combine sensor group-related data structures into struct tegra_tsensor_group. This provides a single location for sensor group data storage. More sensor group data will be added in subsequent patches. Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
2016-05-17thermal: tegra: move tegra thermal files into tegra directoryWei Ni3-0/+477
Move Tegra soctherm driver to tegra directory, it's easy to maintain and add more new function support for Tegra platforms. This will also help to split soctherm driver into common parts and chip specific data related parts. Signed-off-by: Wei Ni <wni@nvidia.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
