Ensure that all error handling branches print error information. In this way, when this function fails, the upper-layer functions can directly return an error code without missing debugging information. Otherwise, the error message will be printed redundantly or missing. Signed-off-by:

Uwe Kleine-König authored
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. st_thermal_unregister() always returned zero, so convert it to return void without any loss and then just drop the return from st_mmap_remove().

The thermal framework is migrating to the generic trip points. The set of changes also implies a self-encapsulation of the thermal zone device structure where the internals are no longer directly accessible but with accessors. Use the new API instead, so the next changes can be pushed in the thermal framework without this driver failing to compile. No functional changes intended.

Should an error occur after calling sun8i_ths_resource_init() in the probe function, some resources need to be released, as already done in the .remove() function. Switch to the devm_clk_get_enabled() helper and add a new devm_action to turn sun8i_ths_resource_init() into a fully managed function. Move the place where reset_control_deassert() is called so that the recommended order of reset release/clock enable steps is kept. A64 manual states that: 3.3.6.4. Gating and reset Make sure that the reset signal has been released before the release of module clock gating; This fixes the issue and removes some LoC at the same time.

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].

MSM8909 uses the TSENS v0.1 block similar to other SoCs like MDM9607. Document the "qcom,msm8909-tsens" compatible in the existing schema. Acked-by:

Stephan Gerhold authored
Since the SoC compatibles must be followed by the IP version compatible (e.g. compatible = "qcom,msm8916-tsens", "qcom,tsens-v0_1";) it is redundant to list all the SoC compatibles again in the if statement. It will already match the IP-version compatible. The list has already become inconsistent since for example "qcom,msm8939-tsens" is covered by the if statement but is not listed there explicitly like the other SoCs. Simplify this by dropping the redundant SoC compatibles. ipq8064 and msm8960 are still needed because they do not have an IP-version compatible. Reviewed-by:

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.

For many setups the bang-bang governor is exactly what we want. Many ARM SoC-based devices use fans to cool down the entire SoC and that works well only with the bang-bang governor because it uses the hysteresis in order to let the fan run for a while to cool the SoC down below the trip point before switching it off again. The step-wise governor will behave strangely in these situations. It doesn't use the hysteresis, so it can lead to situations where the fan is turned on for only a very brief period and then is switched back off, only to get switched back on again very quickly because the SoC hasn't cooled down very much.
