From c91c1c844ebd868ad15bcfc866879fca1079234a Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Sun, 11 Nov 2018 15:15:33 +0100 Subject: iio: imu: st_lsm6dsx: add i2c embedded controller support i2c controller embedded in lsm6dx series can connect up to four slave devices using accelerometer sensor as trigger for i2c read/write operations. Introduce sensor hub support for lsm6dso sensor. Add register map for lis2mdl magnetometer sensor. In order to perform single read/write operations st_lsm6dsx driver relies on SLV0 channel (hw FIFO is not supported yet) Signed-off-by: Lorenzo Bianconi Signed-off-by: Jonathan Cameron --- include/linux/platform_data/st_sensors_pdata.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/linux/platform_data') diff --git a/include/linux/platform_data/st_sensors_pdata.h b/include/linux/platform_data/st_sensors_pdata.h index f8274b0c6888..728193111c2f 100644 --- a/include/linux/platform_data/st_sensors_pdata.h +++ b/include/linux/platform_data/st_sensors_pdata.h @@ -18,11 +18,13 @@ * Accelerometer DRDY on LSM330 available only on pin 1 (see datasheet). * @open_drain: set the interrupt line to be open drain if possible. * @spi_3wire: enable spi-3wire mode. + * @pullups: enable/disable i2c controller pullup resistors. */ struct st_sensors_platform_data { u8 drdy_int_pin; bool open_drain; bool spi_3wire; + bool pullups; }; #endif /* ST_SENSORS_PDATA_H */ -- cgit v1.2.3
