* thermal/hwmon: Do not set no_hwmon before calling thermal_add_hwmon_sysfs()Daniel Lezcano2023-03-031-1/+0
| | | | | | | | | | | | | | | | | The thermal->tzp->no_hwmon parameter is only used when calling thermal_zone_device_register(). Setting it to 'false' before calling thermal_add_hwmon_sysfs() has no effect. Remove the call and again prevent the drivers to access the thermal internals.

* thermal/core: Use the thermal zone 'devdata' accessor in thermal located driversDaniel Lezcano2023-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The thermal zone device structure is exposed to the different drivers and obviously they access the internals while that should be restricted to the core thermal code. In order to self-encapsulate the thermal core code, we need to prevent the drivers accessing directly the thermal zone structure and provide accessor functions to deal with. Use the devdata accessor introduced in the previous patch. No functional changes intended.

* thermal/drivers/rzg2l: Switch to new of APIDaniel Lezcano2022-08-171-5/+5
| | | | | | | | | | | | | The thermal OF code has a new API allowing to migrate the OF initialization to a simpler approach. The ops are no longer device tree specific and are the generic ones provided by the core code. Convert the ops to the thermal_zone_device_ops format and use the new API to register the thermal zone with these generic ops.

* thermal/drivers/rzg2l: Fix commentsBiju Das2022-07-281-7/+11
| | | | | | | | | | | | | | | | This patch replaces 'Capture times'->'Total number of ADC data samples' as the former does not really explain much. It also fixes the typo * caliberation->calibration Lastly, as per the coding style /* should be on a separate line. This patch fixes this issue.

* thermal/drivers/rz2gl: Fix OTP Calibration Register valuesBiju Das2022-05-191-2/+8
| | | | | | | | | | | | | As per the latest RZ/G2L Hardware User's Manual (Rev.1.10 Apr, 2022), the bit 31 of TSU OTP Calibration Register(OTPTSUTRIM) indicates whether bit [11:0] of OTPTSUTRIM is valid or invalid. This patch updates the code to reflect this change.

* thermal/drivers/rz2gl: Add error check for reset_control_deassert()Biju Das2021-12-091-2/+4
| | | | | | | | | | | | | | | If reset_control_deassert() fails, then we won't be able to access the device registers. Therefore check the return code of reset_control_deassert() and bail out in case of error. While at it replace the parameter "&pdev->dev" -> "dev" in devm_reset_control_get_exclusive().

* thermal/drivers: Add TSU driver for RZ/G2LBiju Das2021-11-301-0/+240
The RZ/G2L SoC incorporates a thermal sensor unit (TSU) that measures the temperature inside the LSI. The thermal sensor in this unit measures temperatures in the range from −40 degree Celsius to 125 degree Celsius with an accuracy of ±3°C. The TSU repeats measurement at 20 microseconds intervals and automatically updates the results of measurement. The TSU has no interrupts as well as no external pins. This patch adds Thermal Sensor Unit(TSU) driver for RZ/G2L SoC.
