iio: magnetometer: ak8974: Fix negative raw values in sysfs

2020-03-25T07:27:03Z

commit b500c086e4110829a308c23e83a7cdc65b26228a upstream. At the moment, reading from in_magn_*_raw in sysfs tends to return large values around 65000, even though the output of ak8974 is actually limited to ±32768. This happens because the value is never converted to the signed 16-bit integer variant. Add an explicit cast to s16 to fix this.

iio: st: Drop GPIO include

2019-10-27T15:55:45Z

None of the ST sensor drivers use any symbols from , just drop the include from all of them. Signed-off-by: Linus Walleij Signed-off-by: Jonathan Cameron

iio:st_sensors: remove buffer allocation at each buffer enable

2019-08-11T08:26:04Z

This patch is removing the buffer allocation at each buffer enable. We just allocate enough memory in the main structure during probe to cover maximum size needed (that anyway is pretty small) [16bytes]. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio: remove get_irq_data_ready() function pointer and use IRQ number directly

2019-08-05T15:50:08Z

Not even sure why it was there since the beginning. Just use IRQ number in the sensor_data struct. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio:magn: preenable/postenable/predisable fixup for ST magn buffer

2019-08-05T14:49:18Z

This patch is trying to cleanup for good the buffers operation functions. Let's rename the goto label using operation to perform and not where it fails. Not stable material as not fixing a 'bug' but rather bringing the driver in line with general 'patterns' to allow a subsystem wide cleanup.

iio: magnetometer: mmc35240: Fix a typo in the name of a constant

2019-07-27T21:52:07Z

Everything is about mmc35240_ except MMC53240_WAIT_SET_RESET (3 and 5 switched). This is likely a typo. Define and use MMC35240_WAIT_SET_RESET instead. Signed-off-by: Christophe JAILLET Signed-off-by: Jonathan Cameron

iio: make st_sensors drivers use regmap

2019-07-27T21:52:06Z

This patch is meant to replace the i2c/spi transfer functions with regmap. SPI framework requires DMA safe buffers so let's add GFP_DMA flag for memory allocation used by bulk_read functions. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio: move 3-wire spi initialization to st_sensors_spi

2019-07-27T21:52:06Z

Some devices need to be configured with special bit in order to use spi 3-wire. This was done during device identification phase. Instead, let's move this part as spi specific. Doing this the check_device_support function becomes a simple device id check, so let's rename it. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio:magn: device settings are set immediately during probe

2019-07-27T21:52:05Z

This patch set magn settings right after probe start. This is done in preparation of regmap that needs different configuration based on multiread bit value. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron

iio:magn: introduce st_magn_get_settings() function

2019-07-27T21:52:05Z

The function is introduced to retrieve magn device settings. It will be used by probe in order to configure regmap. Signed-off-by: Denis Ciocca Signed-off-by: Jonathan Cameron
