2023-10-27hwmon: (sch5636) Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
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 ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() is renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-10-27hwmon: (sch5627) Add support for writing limit registersArmin Wolf3-55/+153
After some testing on a Fujitsu Esprimo P720, it turned out that the limit registers are indeed writable and affect the fan control algorithm. This is supported by the datasheet, which says that the fan control functions are based on the limit and parameter registers. Since accessing those registers is very inefficient, the existing regmap cache is used to cache those registers values. Tested on a Fujitsu Esprimo P720.

2023-10-27hwmon: (pmbus/tda38640) Add workaround for SVID modePatrick Rudolph1-2/+152
TDA38640 can operate in either PMBus mode or SVID mode. In SVID mode, by design ENABLE pin is the only option for controlling the output rail i.e., ENABLE pin is chained to power good of another reglator & FPGA. In cases where the chip is configured for SVID mode, and the ENABLE pin is set at a fixed level or is left unconnected (with an internal pull-down), while requiring software control, the following workaround is necessary. The workaround utilizes ENABLE pin polarity flipping to control output rail. If property 'infineon,en-pin-fixed-level' is specified then determine if chip is in SVID mode by checking BIT15 of MTP memory offset 0x44 as described in the datasheet. If chip is in SVID mode then apply the workaround by 1. Determine EN pin level 2. Maps BIT7 of OPERATION(01h) to EN_PIN_POLARITY(BIT1) of PB_ON_OFF_CONFIG.

2023-10-25hwmon: (nct6775) Fix incorrect variable reuse in fan_div calculationZev Weiss1-4/+8
In the regmap conversion in commit 4ef2774511dc ("hwmon: (nct6775) Convert register access to regmap API") I reused the 'reg' variable for all three register reads in the fan speed calculation loop in nct6775_update_device(), but failed to notice that the value from the first one (data->REG_FAN[i]) is actually used in the call to nct6775_select_fan_div() at the end of the loop body. Since that patch the register value passed to nct6775_select_fan_div() has been (conditionally) incorrectly clobbered with the value of a different register than intended, which has in at least some cases resulted in fan speeds being adjusted down to zero. Fix this by using dedicated temporaries for the two intermediate register reads instead of 'reg'.

2023-08-21hwmon: pmbus: Fix -EIO seen on pli1209Patrick Rudolph1-0/+26
After doing performance optimizations the pli1209 driver failed to probe with a probabilty of 2%. It wasn't able to read the PMBUS_OPERATION register due to an -EIO error. An investigation showed that the PLI1209 takes 230 usec to execute the CLEAR_FAULTS command. During that time it's busy and NACKs all requests on the SMBUS interface. It also NACKs reads on PMBUS_STATUS_BYTE making it impossible to poll the BUSY flag. Add a custom write_data function to just wait for not BUSY unconditionally after sending a CLEAR_FAULTS command. TEST: Verified using an I2C bus analyser that no more NACKs are seen after sending a CLEAR_FAULTS command.

2023-08-21hwmon: pmbus: Reduce clear fault page invocationsPatrick Rudolph1-1/+2
Observing I2C traffic revealed consecutive transmission of CLEAR_FAULT commands. While this doesn't cause issues, it extends driver probe time. Avoid invoking pmbus_clear_fault_page for virtual registers, as they're managed by the driver, not the chip. TEST: Verified using an I2C bus analyzer that only one CLEAR_FAULT command is send instead 5 in a row.
