2025-06-26iio: adc: ad7768-1: add regulator to control VCM outputJonathan Santos
The VCM output voltage can be used as a common-mode voltage within the amplifier preconditioning circuits external to the AD7768-1. This change allows the user to configure VCM output using the regulator framework.

2025-06-26dt-bindings: iio: adc: ad7768-1: add trigger-sources propertyJonathan Santos
In addition to GPIO synchronization, The AD7768-1 also supports synchronization over SPI, which use is recommended when the GPIO cannot provide a pulse synchronous with the base MCLK signal. It consists of looping back the SYNC_OUT to the SYNC_IN pin and send a command via SPI to trigger the synchronization. Introduce the 'trigger-sources' property to enable SPI-based synchronization via SYNC_OUT pin, along with additional optional entries for GPIO3 and DRDY pins. Also create #trigger-source-cells property to differentiate the trigger sources provided by the ADC. To improve readability, create a adi,ad7768-1.h header with the macros for the cell values. While at it, add description to the interrupts property.

These macro definitions are completely unused. Remove them. Signed-off-by: Waqar Hameed <waqar.hameed@axis.com> Link: https://patch.msgid.link/0dec4fe7b2bdc90d06163ac75a53b97d4ae31c21.1748356671.git.waqar.hameed@axis.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2025-06-09iio: Remove single use of macro definition for regmap nameWaqar Hameed
There is really no reason for having the `regmap` name as a macro definition if it is only used once directly in `struct regmap_config`. It is also more readable this way. Remove these macro definitions and instead use the string literal directly.

2025-06-09iio: imu: inv_mpu6050: refactor aux read/write to use shared xfer logicIsabella Caselli
Refactors inv_mpu_aux_read() and inv_mpu_aux_write() to extract the common I2C transfer sequence into inv_mpu_i2c_master_xfer(), which now handles starting and stopping the I2C master, waiting for completion, disabling SLV0, and checking for NACK errors. This refactoring removes code duplication and improves maintainability. No functional changes are intended.
