thermal: imx_tmu: support i.MX8MP

2020-05-10T18:55:20Z

Support i.MX8MP thermal which has two probes and supports temperature range from -40 to 125. Still uses default 1p HW calibration at 25C and loads calibration parameters from fuse. Signed-off-by: Ye Li Signed-off-by: Peng Fan

thermal: imx_tmu: Check the TEMP range for iMX8MM

2020-05-10T18:55:20Z

On iMX8MM, the V flag in TRISTR register only reflect the state of SNSR value, not the calibrated TEMP value. So checking this flag is not reliable. Per IC suggestion, change to read the TEMP/AVG_TEMP directly and check whether it in valid range 10-125C. Signed-off-by: Ye Li Signed-off-by: Peng Fan

thermal: imx_tmu: Fix for temperature out of range

2020-05-10T18:55:20Z

When the temperature is out of sensor's range, the Valid bit won't be set in TRITSR register. So the polling loop won't go out. Change the codes to retry 10 times with 100ms interval for the Valid bit. If the timeout, we give a warning for the invalid data. Modifed from Ye's NXP patch Signed-off-by: Peng Fan

thermal: imx_tmu: support TMU arch level initialization

2020-05-10T18:55:20Z

i.MX8MM TMU needs to load some registers from fuse, this is arch dependent operation and may vary on different platforms. So add a interface for arch level initialization. Signed-off-by: Peng Fan

thermal: imx_tmu: Add support for thermal sensor on iMX8MM

2020-05-10T18:55:20Z

The analog sensors on iMX8MM are new, used for 14LPP process. So the Temperature Sensor Monitoring Unit (TMU) has some change accordingly. We use version 2 in TMU driver to represent the new TMU, so the one driver can service for both i.MX8MQ/M. Signed-off-by: Peng Fan

thermal: Add thermal driver for i.MX8M

2020-05-10T18:55:20Z

The driver is ported form Linux Kernel and support driver model. Users need to provide the tmu node and sensors nodes in DTB. Signed-off-by: Ye Li Signed-off-by: Peng Fan

thermal: imx_scu_thermal: Update driver for i.MX8QM thermal sensor

2020-05-10T18:55:20Z

Add iMX8QM thermal compatible string and its driver data. Signed-off-by: Ye Li Signed-off-by: Peng Fan

thermal: ti-bandgap: Fix adc value datatype

2020-01-20T04:40:28Z

The CORE_TEMP_SENSOR_MPU register gives a raw adc value which needs to be indexed into a lookup table to get the actual temperature. Fix the naming and datatype of the adc value variable. Signed-off-by: Faiz Abbas Signed-off-by: Lokesh Vutla

thermal: add i.MX8 thermal driver

2019-07-19T13:17:05Z

Add i.MX8 thermal driver to support get temperature from SCU. Signed-off-by: Peng Fan

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini
