2023-09-12T09:42:03+00:00

Commit 0f3a8c3f34f7 ("iio: Add support for creating IIO devices via configfs") declared but never implemented iio_sw_device_type_configfs_{un}register(). Commit b662f809d410 ("iio: core: Introduce IIO software triggers") declared but never implemented iio_sw_trigger_type_configfs_{un}register(). Commit a3e0b51884ee ("iio: accel: add support for FXLS8962AF/FXLS8964AF accelerometers") declared but never implemented fxls8962af_core_remove(). Commit 8dedcc3eee3a ("iio: core: centralize ioctl() calls to the main chardev") declared but never implemented iio_device_ioctl(). Commit d430f3c36ca6 ("iio: imu: inv_mpu6050: Use regmap instead of i2c specific functions") removed inv_mpu6050_write_reg() but not its declaration.

iio: make function argument and some structures const

2017-10-19T14:15:24+00:00

Make the argument of the functions iio_sw{d/t}_group_init_type_name const as they are only passed to the function config_group_init_type_name having the argument as const. Make the config_item_type structures const as they are either passed to the functions having the argument as const or they are stored in the const "ci_type" field of a config_item structure.

iio: sw-device: Fix config group initialization

2017-03-13T20:42:34+00:00

Use the IS_ENABLED() helper macro to ensure that the configfs group is initialized either when configfs is built-in or when configfs is built as a module. Otherwise software device creation will result in undefined behaviour when configfs is built as a module since the configfs group for the device not properly initialized. Similar to commit b2f0c09664b7 ("iio: sw-trigger: Fix config group initialization").

iio: Add support for creating IIO devices via configfs

2016-05-04T10:43:54+00:00

This is similar with support for creating triggers via configfs. Devices will be hosted under: * /config/iio/devices We allow users to register "device types" under: * /config/iio/devices// Signed-off-by: Daniel Baluta Signed-off-by: Jonathan Cameron
