staging: iio: ad2s1210: Fix SPI reading

2020-05-03T11:35:03+00:00

If the serial interface is used, the 8-bit address should be latched using the rising edge of the WR/FSYNC signal. This basically means that a CS change is required between the first byte sent, and the second one. This change splits the single-transfer transfer of 2 bytes into 2 transfers with a single byte, and CS change in-between. Note fixes tag is not accurate, but reflects a point beyond which there are too many refactors to make backporting straight forward.

staging: iio: adc: ad7280a: Add comments to clarify stringified arguments

2020-03-23T10:45:20+00:00

Checkpatch would flash a check message around a stringified macro argument containing a '-' character. Add comment to indicate the argument is legitimate and doesn't need fixing.

staging: iio: update TODO

2020-03-08T17:28:43+00:00

Since there are no uses of the old GPIO API, remove the item from the TODO. Signed-off-by: Rohit Sarkar Signed-off-by: Jonathan Cameron

staging: iio: adc: ad7192: move out of staging

2020-03-08T17:28:33+00:00

Move ad7192 ADC driver out of staging into mainline. Signed-off-by: Alexandru Tachici Signed-off-by: Jonathan Cameron

Documentation: ABI: testing: ad7192: update sysfs docs

2020-03-08T17:28:33+00:00

Updated mainline documentation on ad7192 userspace sysfs. Signed-off-by: Alexandru Tachici Signed-off-by: Jonathan Cameron

staging: iio: adc: ad7192: removed spi_device_id

2020-03-08T17:28:32+00:00

This patch removes spi_device_id table and moves the init data (id of the chip) in the .data field of of_device_id table. Signed-off-by: Alexandru Tachici Signed-off-by: Jonathan Cameron

staging: iio: adc: ad7192: modify iio_chan_spec array

2020-03-08T17:28:32+00:00

This patch changes the static const struct iio_chan_spec arrays in a way that all the necessary attributes are set at compile time. Now ad7192_channels_config only makes the channels attribute of iio_dev point to the right array depending on the chip. Signed-off-by: Alexandru Tachici Signed-off-by: Jonathan Cameron

staging: iio: adc: ad7192: fail probe on get_voltage

2020-03-08T17:28:32+00:00

This patch makes the ad7192_probe fail in case regulator_get_voltage will return an error or voltage is set to 0. Signed-off-by: Alexandru Tachici Signed-off-by: Jonathan Cameron

iio: imu: adis: Add self_test_reg variable

2020-03-08T17:28:30+00:00

This patch adds a dedicated self_test_reg variable. This is also a step to let new drivers make use of `adis_initial_startup()`. Some devices use MSG_CTRL reg to request a self_test command while others use the GLOB_CMD register. Signed-off-by: Nuno Sá Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: adis: Remove startup_delay

2020-01-12T11:34:13+00:00

All timeouts are now handled by a dedicated timeout struct. This variable is no longer needed. Signed-off-by: Nuno Sá Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron
