Everything is about mmc35240_ except MMC53240_WAIT_SET_RESET (3 and 5 switched). This is likely a typo. Define and use MMC35240_WAIT_SET_RESET instead. Signed-off-by:

The ADIS16460 device is a complete inertial system that includes a triaxial gyroscope and a triaxial accelerometer. It's more simplified design than that of the ADIS16480, and does not offer the triaxial magnetometers & pressure sensors. It does also have a temperature sensor (like the ADIS16480). Since it is part of the ADIS16XXX family, it re-uses parts of the ADIS library. Naturally, the register map is different and much more simplified than the ADIS16480 subfamily, so it cannot be integrated into that driver. A major difference is that the registers are not paged. One thing that is particularly special about it, is that it requires a higher delay between CS changes (i.e. when CS goes up, the spec recommends that it be brought down after a minimum of 16 uS). Other ADIS chips require (via spec) a minimum of 2 uS between CS changes. The kernel's 10 uS default should be fine for those other chips; they haven't been tested with lower CS change delays yet.

The ADIS16460 requires a higher delay before the next transfer. Since the SPI framework supports configuring the delay before the next transfer, this driver will become the first user of it. The support for this functionality in ADIS16460 requires an addition to the ADIS lib to support the `cs_change_delay` functionality from the SPI subsystem. Signed-off-by:

This patch is meant to replace the i2c/spi transfer functions with regmap. SPI framework requires DMA safe buffers so let's add GFP_DMA flag for memory allocation used by bulk_read functions. Signed-off-by:

Some devices need to be configured with special bit in order to use spi 3-wire. This was done during device identification phase. Instead, let's move this part as spi specific. Doing this the check_device_support function becomes a simple device id check, so let's rename it. Signed-off-by:

On stm32h7 and stm32mp1, the ADC inputs are multiplexed with analog switches which have reduced performances when their supply is below 2.7V (vdda by default): - 3.3V embedded booster can be used, to get full ADC performances (increases power consumption). - vdd supply can be selected if above 2.7V by setting ANASWVDD syscfg bit, on STM32MP1 only. Make this optional, since this is a trade-off between analog performance and power consumption. Signed-off-by:

Add documentation for: - optional booster-supply that can be used on stm32h7 and stm32mp1. - optional vdd-supply that can be used on stm32mp1 to supply analog circuitry, selected by syscfg.

iio: imu: mpu6050: Replace devm_add_action() followed by failure action with devm_add_action_or_reset() devm_add_action_or_reset() is introduced as a helper function which internally calls devm_add_action(). If devm_add_action() fails then it will execute the action mentioned and return the error code. This reduce source code size (avoid writing the action twice) and reduce the likelyhood of bugs.
