iio: imu: adis: Add self_test_reg variable

2020-03-08T17:28:30Z

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: gyro: adis16136: initialize adis_data statically

2020-03-08T17:28:29Z

This change overrides commit 380b107bbf944 ("iio: adis: Introduce timeouts structure"). It removes the memory allocation and moves the 'adis_data' information to be static on the chip_info struct. This also adds a timeout structure to ADIS16334, since it was initially omitted. This was omitted (by accident) when the change was done.

iio: st_sensors: Make use of device properties

2020-01-13T21:53:39Z

Device property API allows to gather device resources from different sources, such as ACPI. Convert the drivers to unleash the power of device property API. Signed-off-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: st_sensors: Drop redundant parameter from st_sensors_of_name_probe()

2020-01-13T21:51:52Z

Since we have access to the struct device_driver and thus to the ID table, there is no need to supply special parameters to st_sensors_of_name_probe(). Besides that we have a common API to get driver match data, there is no need to do matching separately for OF and ACPI. Taking into consideration above, simplify the ST sensors code.

iio: st_gyro: Correct data for LSM9DS0 gyro

2020-01-13T21:49:20Z

The commit 41c128cb25ce ("iio: st_gyro: Add lsm9ds0-gyro support") assumes that gyro in LSM9DS0 is the same as others with 0xd4 WAI ID, but datasheet tells slight different story, i.e. the first scale factor for the chip is 245 dps, and not 250 dps. Correct this by introducing a separate settings for LSM9DS0.

iio: adis: Remove startup_delay

2020-01-12T11:34:13Z

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

iio: adis: Introduce timeouts structure

2020-01-12T11:34:12Z

The adis library only allows to define a `startup_delay` which for some devices is enough. However, other devices define different timeouts with significantly different timings which could lead to devices to not wait enough time or to wait a lot more than necessary (which is not efficient). This patch introduces a new timeout struct that must be passed into `adis_init()`. There are mainly, for now, three timeouts used. This is also an introductory patch with the goal of refactoring `adis_initial_startup()`. New driver's (eg: adis16480, adis16460) are replicating code for the device initial setup. With some changes (being this the first one) we can pass this to `adis_initial_startup()`. Signed-off-by: Nuno Sá Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: gyro: st_gyro: Mark gyro_pdata with __maybe_unused

2019-12-29T15:20:05Z

Since we put static variable to a header file it's copied to each module that includes the header. But not all of them are actually used it. Mark gyro_pdata with __maybe_unused to calm a compiler down: In file included from drivers/iio/gyro/st_gyro_i2c.c:18: drivers/iio/gyro/st_gyro.h:31:46: warning: ‘gyro_pdata’ defined but not used [-Wunused-const-variable=] 31 | static const struct st_sensors_platform_data gyro_pdata = { | ^~~~~~~~~~ ...

The driver include yet does not use any of the symbols from the header, so drop the include. Signed-off-by: Linus Walleij Signed-off-by: Jonathan Cameron
