2020-07-20iio: gyro: fxas21002c: Move 'fxas21002c_reg_fields' to the only file its usedLee Jones1-66/+0
'fxas21002c_reg_fields' is only used in '*core*', meaning that '*i2c*' and '*spi*' complain of a defined but not used const variable. Let's move it into the source file. Fixes the following W=1 kernel build warning(s): In file included from drivers/iio/gyro/fxas21002c_i2c.c:14: drivers/iio/gyro/fxas21002c.h:79:31: warning: ‘fxas21002c_reg_fields’ defined but not used [-Wunused-const-variable=] 79 | static const struct reg_field fxas21002c_reg_fields[] = { | ^~~~~~~~~~~~~~~~~~~~~ In file included from drivers/iio/gyro/fxas21002c_spi.c:14: drivers/iio/gyro/fxas21002c.h:79:31: warning: ‘fxas21002c_reg_fields’ defined but not used [-Wunused-const-variable=] 79 | static const struct reg_field fxas21002c_reg_fields[] = { | ^~~~~~~~~~~~~~~~~~~~~ Cc: Rui Miguel Silva <rmfrfs@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2019-04-22iio: gyro: add core driver for fxas21002cRui Miguel Silva1-0/+150
Add core support for the NXP fxas21002c Tri-axis gyroscope, using the iio subsystem. It supports PM operations, axis reading, temperature, scale factor of the axis, high pass and low pass filtering, and sampling frequency selection. It will have extras modules to support the communication over i2c and spi. Signed-off-by: Rui Miguel Silva <rui.silva@linaro.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
