AL3320a is fairly simple chip, so for suspend is enough to disable and later enable it again. Signed-off-by:

Based on: - 3320A in-kernel driver - https://www.spinics.net/lists/linux-iio/msg25145.html - https://lore.kernel.org/patchwork/patch/684179/ I decided to keep it aside of AL3320A due to different approach and much simpler design of 3010. Tested on Nexus 7 2012 (grouper/tilapia). Tested-by:

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:

All of the actions done in `adis16460_initial_setup()` are now done in `__adis_initial_startup()` so, there's no need for code duplication. Signed-off-by:

All actions done in `adis16480_initial_setup()` are now done in `__adis_initial_startup()` so, there's no need for code duplication. Furthermore, the call to `adis16480_initial_setup()` is done before any device configuration since the device will be reset if not already (via rst pin). This is actually fixing a potential bug since `adis_reset()` was being called after configuring the device which is obviously a problem. Signed-off-by:

Each driver/chip that wants to validate it's product id, can now specify a 'prod_id_reg' and an expected 'prod_id' value. The 'prod_id' value is intentionally left 0 (uninitialized). There aren't (yet) any product IDs with value 0; this enforces that both 'prod_id_reg' and 'prod_id' are specified. At the very least, this routine validates that the SPI connection to the ADIS chip[s] works well. Signed-off-by:

All the ADIS devices perform, at the beginning, a self test to make sure the device is in a sane state. Previously, the logic was that the self-test was performed in adis_initial_startup() and if that failed a reset was done and then a self-test was attempted again. This change unifies the reset mechanism under the adis_initial_startup() call. A HW reset will be done if GPIO is configured, or a SW reset otherwise. This should make sure that the chip is in a sane state for self-test. Once the reset is done, the self-test operation will be performed. If anything goes wrong with self-test, the driver should just bail/error-out (i.e. no second attempt). The chip would likely not be a in a sane state state if the self-test fails after a reset.

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:

This change splits the __adis_initial_startup() away from adis_initial_startup(). The unlocked version can be used in certain calls during probe, where races won't happen since the ADIS driver may not be registered yet with IIO. Signed-off-by:

This change overrides commit 380b107b ("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. Signed-off-by:

Modify NPCM ADC reset support from direct register access to reset controller support. please make sure to modify NPCM adc device tree parameters as described at nuvoton,npcm-adc.txt document for using this change. Note for anyone noting that this is a breaking change, this is on a BMC and effectively in a close ecosystem so it is fine to rely on DT and kernel being updated together. Signed-off-by:
