2023-06-26thermal/drivers/stm32: Convert to platform remove callback returning voidUwe Kleine-König3-7/+5
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().

2023-06-26net/mlx5: Update the driver with the recent thermal changesDaniel Lezcano1-7/+8
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.

2023-06-26thermal/drivers/sun8i: Fix some error handling paths in sun8i_ths_probe()Christophe JAILLET1-37/+18
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].

2023-06-26thermal/drivers/qcom/tsens-v0_1: Add mdm9607 correction offsetsStephan Gerhold3-1/+30
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.

2023-06-26thermal: Allow selecting the bang-bang governor as defaultThierry Reding2-0/+10
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.

2023-06-26iscsi_ibft: Fix finding the iBFT under Xen Dom 0Ross Lagerwall1-9/+17
To facilitate diskless iSCSI boot, the firmware can place a table of configuration details in memory called the iBFT. The presence of this table is not specified, nor is the precise location (and it's not in the E820) so the kernel has to search for a magic marker to find it. When running under Xen, Dom 0 does not have access to the entire host's memory, only certain regions which are identity-mapped which means that the pseudo-physical address in Dom0 == real host physical address. Add the iBFT search bounds as a reserved region which causes it to be identity-mapped in xen_set_identity_and_remap_chunk() which allows Dom0 access to the specific physical memory to correctly search for the iBFT magic marker (and later access the full table). This necessitates moving the call to reserve_ibft_region() somewhat later so that it is called after e820__memory_setup() which is when the Xen identity mapping adjustments are applied. The precise location of the call is not too important so I've put it alongside dmi_setup() which does similar scanning of memory for configuration tables. Finally in the iBFT find code, instead of using isa_bus_to_virt() which doesn't do the right thing under Xen, use early_memremap() like the dmi_setup() code does. The result of these changes is that it is possible to boot a diskless Xen + Dom0 running off an iSCSI disk whereas previously it would fail to find the iBFT and consequently, the iSCSI root disk.

2023-06-23regulator: Add Renesas PMIC RAA215300 driverBiju Das3-0/+198
The RAA215300 is a 9-channel PMIC that consists of * Internally compensated regulators * built-in Real Time Clock (RTC) * 32kHz crystal oscillator * coin cell battery charger The RTC on RAA215300 is similar to the IP found in the ISL1208. The existing driver for the ISL1208 works for this PMIC too, however the RAA215300 exposes two devices via I2C, one for the RTC IP, and one for everything else. The RTC IP has to be enabled by the other I2C device, therefore this driver is necessary to get the RTC to work. The external oscillator bit is inverted on PMIC version 0x11. Add PMIC RAA215300 driver for enabling RTC block and instantiating RTC device based on PMIC version.

2023-06-23clocksource/drivers/hyper-v: Rework clocksource and sched clock setupMichael Kelley1-31/+23
Current code assigns either the Hyper-V TSC page or MSR-based ref counter as the sched clock. This may be sub-optimal in two cases. First, if there is hardware support to ensure consistent TSC frequency across live migrations and Hyper-V is using that support, the raw TSC is a faster source of time than the Hyper-V TSC page. Second, the MSR-based ref counter is relatively slow because reads require a trap to the hypervisor. As such, it should never be used as the sched clock. The native sched clock based on the raw TSC or jiffies is much better. Rework the sched clock setup so it is set to the TSC page only if Hyper-V indicates that the TSC may have inconsistent frequency across live migrations. Also, remove the code that sets the sched clock to the MSR-based ref counter. In the cases where it is not set, the sched clock will then be the native sched clock. As part of the rework, always enable both the TSC page clocksource and the MSR-based ref counter clocksource. Set the ratings so the TSC page clocksource is preferred. While the MSR-based ref counter clocksource is unlikely to ever be the default, having it available for manual selection is convenient for development purposes.

2023-06-23spi: Helper for deriving timeout valuesMark Brown2-8/+12
Merge series from Miquel Raynal <miquel.raynal@bootlin.com>: I recently came across an issue with the Atmel spi controller driver which would stop my transfers after a too small timeout when performing big transfers (reading a 4MiB flash in one transfer). My initial idea was to derive a the maximum amount of time a transfer would take depending on its size and use that as value to avoid erroring-out when not relevant. Mark wanted to go further by creating a core helper doing that, based on the heuristics from the sun6i driver. Here is a small series of 3 patches doing exactly that.
2023-06-22spi: sun6i: Use the new helper to derive the xfer timeout valueMiquel Raynal1-1/+1
A helper was recently added to the core to factorize common code between drivers, like the amount of time a driver should wait for a transfer to happen. It is of course possible to use a default value (like eg. 1s) but it is way stronger to adapt this amount of time to the transfer. Indeed, long transfers (eg. 4MiB) on a slow single-spi bus might take more than the usual second of timeout and prevent lengthy transfers. The core helper was heavily inspired by the logic applied in this driver, the only difference being the minimum amount of time which was enlarged from 0.1s to 0.5s. Use this helper instead of open-coding it.
