2018-10-23thermal: tsens: Rename map field in order to add a second address mapAmit Kucheria4-28/+27
The TSENS driver currently only uses a limited set of registers from the TM address space. So it was ok to map just that set of registers and call it "map". We'd now like to map a second set: SROT registers to introduce new functionality. Rename the "map" field to a more appropriate "tm_map". The 8960 doesn't have a clear split between TM and SROT registers. To avoid complicating the data structure, it will switchover to using tm_map for its maps.

2018-08-25thermal: qcom-spmi: Use PMIC thermal stage 2 for critical trip pointsMatthias Kaehlcke1-18/+140
There are three thermal stages defined in the PMIC: stage 1: warning stage 2: system should shut down stage 3: emergency shut down By default the PMIC assumes that the OS isn't doing anything and thus at stage 2 it does a partial PMIC shutdown and at stage 3 it kills all power. When switching between thermal stages the PMIC generates an interrupt which is handled by the driver. The partial PMIC shutdown at stage 2 can be disabled by software, which allows the OS to initiate a shutdown at stage 2 with a thermal zone configured accordingly. If a critical trip point is configured in the thermal zone the driver adjusts the stage 1-3 temperature thresholds to (closely) match the critical temperature with a stage 2 threshold (125/130/135/140 °C). If a suitable match is found the partial shutdown at stage 2 is disabled. If for some reason the system doesn't shutdown at stage 2 the emergency shutdown at stage 3 kicks in. The partial shutdown at stage 2 remains enabled in these cases: - no critical trip point defined - the temperature of the critical trip point is < 125°C - the temperature of the critical trip point is > 140°C and no ADC channel is configured (thus the OS is not notified when the critical temperature is reached) Suggested-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Reviewed-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>

2018-08-20thermal: qoriq: Simplify the 'site' variable assignmentFabio Estevam1-2/+2
There is no need to assign zero to the variable 'site' and then perform a compound bitwise OR operation afterwards. Make it simpler by assigning the final 'site' value directly.

2018-08-20thermal: qoriq: Use devm_thermal_zone_of_sensor_register()Fabio Estevam1-4/+3
By using the managed devm_thermal_zone_of_sensor_register() we can drop the explicit call to thermal_zone_of_sensor_unregister() in the qoriq_tmu_remove() function, which simplifies the code a bit. So switch to devm_thermal_zone_of_sensor_register().

2018-07-28thermal: rcar_thermal: avoid NULL dereference in absence of IRQ resourcesSimon Horman1-1/+1
Ensure that the base address used by a call to rcar_thermal_common_write() may be NULL if the SOC supports interrupts for use with the thermal device but none are defined in DT as is the case for R-Car H1 (r8a7779). Guard against this condition to prevent a NULL dereference when the device is probed. Tested on: * R-Mobile APE6 (r8a73a4) / APE6EVM * R-Car H1 (r8a7779) / Marzen * R-Car H2 (r8a7790) / Lager * R-Car M2-W (r8a7791) / Koelsch * R-Car M2-N (r8a7793) / Gose * R-Car D3 ES1.0 (r8a77995) / Draak Fixes: 1969d9dc2079 ("thermal: rcar_thermal: add r8a77995 support") Signed-off-by: Simon Horman <horms+renesas@verge.net.au> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
