thermal/drivers/qcom/lmh: Check for SCM availability at probe

2024-06-16T11:47:33+00:00

commit d9d3490c48df572edefc0b64655259eefdcbb9be upstream. Up until now, the necessary scm availability check has not been performed, leading to possible null pointer dereferences (which did happen for me on RB1). Fix that.

thermal/drivers/tsens: Fix null pointer dereference

2024-06-12T09:11:43+00:00

[ Upstream commit d998ddc86a27c92140b9f7984ff41e3d1d07a48f ] compute_intercept_slope() is called from calibrate_8960() (in tsens-8960.c) as compute_intercept_slope(priv, p1, NULL, ONE_PT_CALIB) which lead to null pointer dereference (if DEBUG or DYNAMIC_DEBUG set). Fix this bug by adding null pointer check. Found by Linux Verification Center (linuxtesting.org) with SVACE.

thermal: Explicitly include correct DT includes

2023-07-31T18:03:42+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

Use the dev_err_probe function instead of dev_err in the probe function so that the printed message includes the return value and also handles -EPROBE_DEFER nicely.

thermal/drivers/qcom/tsens-v0_1: Add MSM8909 data

2023-06-26T10:03:13+00:00

The MSM8909 SoC has 5 thermal sensors in a TSENS v0.1 block. Like MDM9607 it uses a non-standard default slope value of 3000 [1] and needs per-sensor "correction factors" to workaround issues with the factory calibration [2].

thermal/drivers/qcom/tsens-v0_1: Add mdm9607 correction offsets

2023-06-26T10:03:13+00:00

According to the msm-3.18 vendor kernel from Qualcomm, mdm9607 needs "correction factors" to adjust for additional offsets observed after the factory calibration values in the fuses [1, 2]. The fixed offsets should be applied unless there is a special calibration mode value that indicates that no offsets are needed [3]. Note that the new calibration mode values are called differently in this patch compared to the vendor kernel: - TSENS_TWO_POINT_CALIB_N_WA -> ONE_PT_CALIB2_NO_OFFSET - TSENS_TWO_POINT_CALIB_N_OFFSET_WA -> TWO_PT_CALIB_NO_OFFSET This is because close inspection of the calibration function [3] reveals that TSENS_TWO_POINT_CALIB_N_WA is actually a "one point" calibration because the if statements skip all "point2" related code for it.
