From 317c9bef82ebe369fd1dac428eac505b5b6ff531 Mon Sep 17 00:00:00 2001 From: Francesco Lavra Date: Mon, 1 Dec 2025 11:00:17 +0100 Subject: [PATCH] iio: imu: st_lsm6dsx: add event spec parameter to iio_chan_spec initializer In preparation for adding support for more event sources, add to the ST_LSM6DSX_CHANNEL_ACC() iio_chan_spec initializer macro an iio_event_spec array argument, so that this macro can be used with different arrays by sensors that support different event sources; change the st_lsm6dsx_event struct declaration to an array (renamed as st_lsm6dsx_ev_motion) so that it can be passed to the macro (and opportunistically move it from the header file where it does not belong to the C file where it is used). In addition, remove from this macro the channel type parameter and hard-code IIO_ACCEL in the macro definition, since all callers use IIO_ACCEL as channel type argument.
