Introduce regmap API support to access to i2c/spi bus instead of using a custom support. Set max bulk read to (32 / SAMPLE_SIZE) * SAMPLE_SIZE since spi_write_then_read() used in regmap_spi indicates that is the max buffer length to use in order to avoid a kmalloc for each bus access. Remove lock mutex since concurrency is already managed by regmap API Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Say yes here to build support for STMicroelectronics LSM6DSx imu
|
|
sensor. Supported devices: lsm6ds3, lsm6ds3h, lsm6dsl, lsm6dsm
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called st_lsm6dsx.
