Since commit 6020ca4d ("iio: adc: ad7944: use spi_optimize_message()"), The helper functions wrapping spi_sync() for 3-wire and 4-wire modes are virtually identical. Since gpiod_set_value_cansleep() does a NULL check internally, we can consolidate the two functions into one and avoid switch statements at the call sites. The default cases of the removed switch statement were just to make the compiler happy and are not reachable since the mode is validated in the probe function. So removing those should be safe.

Before all supported sensors except for MPU{9150,9250,9255} were not allowed to use i2c-gate in the bindings which excluded quite a few supported sensors where this functionality is supported. Switch the list of sensors to ones where the Linux driver explicitly disallows support for the auxiliary bus ("inv_mpu_i2c_aux_bus"). Since the driver is also based on "default: return true" this should scale better into the future. Signed-off-by:Luca Weiss <luca@z3ntu.xyz> Acked-by:

Switching to the _scoped() version removes the need for manual calling of fwnode_handle_put() in the paths where the code exits the loop early. In this case that's all in error paths. A slightly less convincing usecase than many as all the failure paths are wrapped up in a call to a per fwnode_handle utility function. The complexity in that function is sufficient that it makes sense to factor it out even if it this new auto cleanup would enable simpler returns if the code was inline at the call site. Hence I've left it alone. Cc: Marijn Suijten <marijn.suijten@somainline.org> Reviewed-by:

Note this would have made the bug fixed in the previous path much less likely as it allows for direct returns. Took advantage of dev_err_probe() to futher simplify things given no longer a need for the goto err. Cc: Olivier Moysan <olivier.moysan@foss.st.com> Tested-by:

Add a setup function implementation to the spi module to enable spi-3wire when specified in the device-tree. If spi-3wire is not specified in the device-tree, NULL is returned as bus pre-initialization. This behavior is identical to the i2c initialization, hence the default initialization. Signed-off-by:

Provide a way for bus specific pre-configuration by adding a function pointer argument to the driver core's probe() function, and keep the driver core implementation bus independent. In case NULL was passed, a regmap_write() shall initialize all bits of the data_format register, else regmap_update() is used. In this way spi and i2c are covered. Signed-off-by:

Replace write() data_format by regmap_update_bits() to keep bus specific pre-configuration which might have happened before on the same register. The bus specific bits in data_format register then need to be masked out, Remove the data_range field from the struct adxl345_data, because it is not used anymore. Signed-off-by:

Also change both firmware parsing functions to return meaningful errors. Whilst for the ACPI case this isn't that useful, for the generic fwnode case we can return the errors coming from the property parsing instead of just whether we succeeded or not.
