MPU6050 has two power supply pins: VDD and VLOGIC, but the mpu6050 driver only supports enabling one of them at the moment. In some cases, they may need to be enabled separately. Add an additional "vdd-supply" that stays enabled for as long as the driver is loaded. We cannot turn off the VDD regulator during suspend as this would cause register settings (FSR, sampling rate, ...) to be lost. Signed-off-by:

The AD5600 is a single channel, 16-bit resolution, voltage output digital to analog converter (DAC). The AD5600 uses a 3-wire SPI interface. It is part of the AD5541 family of DACs. The ad5446 IIO driver implements support for some of these DACs (in the AD5441 family), so the change is a simple entry in this driver.

Rishi Gupta authored
veml6030 is an ambient light sensor from Vishay semiconductors. It has 16-bit resolution, supports both ambient light measurement and white channel which is more responsive to wider wavelength spectrum. It has flexible power saving, integration time and gain options. Communication with host is over I2C. Signed-off-by:

The inline read functions in the ADIS library don't check the return value of the `adis_read_reg()` function and assign the value of `tmp` regardless. Fix this by checking if return value is zero and only then assigning the value of `tmp`. No known case of the callers of this function incorrectly using the value, but best to stop any potential risk here. Not suitable for stable due to no known actual bugs caused by this issue. Fixes: 57a1228a ("iio:imu:adis: Add support for 32bit registers") Signed-off-by:

This was also caught by the `-Wmaybe-uninitialized` warning, which (ironically as-is) it makes quite a lot of sense to do for this. The code that actually calls this function will fail to copy on the uninitialized value. Hence, patch does not need to go into stable.

This was found only after the whole thing with the inline functions, but the compiler actually found something. The value of the `bias` (in adis16480_get_calibbias()) should only be set if the read operation was successful. No actual known problem occurs as users of this function all ultimately check the return value. Hence probably not stable material.

The ADIS library functions return zero on success, and negative values for error. Positive values aren't returned, but we only care about the success value (which is zero). This change is mostly needed so that the compiler won't make any inferences about some about values being potentially un-initialized. This only triggers after making some functions inline, because the compiler can better follow return paths. Signed-off-by:

The iio_triggered_buffer_postenable() hook should be called first to attach the poll function. The iio_triggered_buffer_predisable() hook is called last (as is it should). This change moves iio_triggered_buffer_postenable() to be called first. It adds iio_triggered_buffer_predisable() on the error paths of the postenable hook. For the predisable hook, some code-paths have been changed to make sure that the iio_triggered_buffer_predisable() hook gets called in case there is an error before it. Signed-off-by:
