2024-08-04i2c: smbus: Send alert notifications to all devices if source not foundGuenter Roeck1-3/+35
If a SMBus alert is received and the originating device is not found, the reason may be that the address reported on the SMBus alert address is corrupted, for example because multiple devices asserted alert and do not correctly implement SMBus arbitration. If this happens, call alert handlers on all devices connected to the given I2C bus, in the hope that this cleans up the situation. This change reliably fixed the problem on a system with multiple devices on a single bus. Example log where the device on address 0x18 (ADM1021) and on address 0x4c (ADT7461A) both had the alert line asserted: smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0 smbus_alert 3-000c: no driver alert()! smbus_alert 3-000c: SMBALERT# from dev 0x0c, flag 0 smbus_alert 3-000c: no driver alert()! lm90 3-0018: temp1 out of range, please check! lm90 3-0018: Disabling ALERT# lm90 3-0029: Everything OK lm90 3-002a: Everything OK lm90 3-004c: temp1 out of range, please check! lm90 3-004c: temp2 out of range, please check! lm90 3-004c: Disabling ALERT# Fixes: b5527a7766f0 ("i2c: Add SMBus alert support") Signed-off-by: Guenter Roeck <[email protected]> [wsa: fixed a typo in the commit message] Signed-off-by: Wolfram Sang <[email protected]>

2024-08-04wifi: brcmfmac: introducing fwil query functionsArend van Spriel5-28/+48
When the firmware interface layer was refactored it provided various "get" and "set" functions. For the "get" in some cases a parameter needed to be passed down to firmware as a key indicating what to "get" turning the output parameter of the "get" function into an input parameter as well. To accommodate this the "get" function blindly copies the parameter which in some places resulted in an uninitialized warnings from the compiler. These have been fixed by initializing the input parameter in the past. Recently another batch of similar fixes were submitted to address clang static checker warnings [1]. Proposing another solution by introducing a "query" variant which is used when the (input) parameter is needed by firmware. The "get" variant will only fill the (output) parameter with the result received from firmware taking care of proper endianess conversion.

During setup the st->adc_control is 0, which corresponds to a continuous conversion mode. The reset value for channel 1 is to enable it. The combined effect of these two is that the ADC will start conversions for channel 1 without them being read. This is not neccessarily a problem, but it is an unexpected behavior.

The ad7124_find_similar_live_cfg() computes the compare size by substracting the address of the cfg struct from the address of the live field. Because the live field is the first field in the struct, the result is 0. Also, the memcmp() call is made from the start of the cfg struct, which includes the live and cfg_slot fields, which are not relevant for the comparison. Fix by grouping the relevant fields with struct_group() and use the size of the group to compute the compare size; make the memcmp() call from the address of the group.

Add separate handling for adf4378 within the driver. The main difference between adf4377 and adf4378 is that adf4378 has only one output which is handled by only one gpio.

2024-08-03iio: light: stk3310: add support for stk3013Kaustabh Chakraborty1-0/+5
Add support for Sensortek's STK3013 in the driver. The part bears the product ID 0x31. As seen in [1], Sensortek lists STK3013 as a proximity sensor. But it has been experimentally observed that they do have ambient light sensing capabilities. Furthermore, [2] implements a proximity and ambient light sensor driver for STK3x1x devices, which is also indicative of the fact that these parts are also ambient light sensors.

In order to allow newer devices which are compatible with existing sensors, issuing a warning for an unknown chipid indicates that something has gone wrong with the init process, which isn't ideal. Swap it with a friendlier info message to get things right.

2024-08-03iio: adc: mcp3564: use devm_regulator_get_enable_read_voltage()David Lechner1-38/+16
This makes use of the new devm_regulator_get_enable_read_voltage() helper function to reduce boilerplate code in the MCP3564 ADC driver. The error message is slightly changed since there are fewer error return paths. Setting adc->vref_mv is consolidated into a single place to make the logic easier to follow. A use_internal_vref_attr local variable is added to make it more obvious what the difference between the two iio info structures is. The return value of the "Unknown Vref" dev_err_probe() is hard-coded to -ENODEV instead of ret since it was getting a bit far from where ret was set and logically that is the only value it could have.
