Split the binding in two to reflect the threshold monitor capabilities and hence interrupts vs the more straight forward parts that don't have this facility. Signed-off-by:

Clock should be enabled as soon as using master modes, even before enabling timer. Or, this may provoke bad behavior on the other end (slave timer). Then, introduce 'clk_enabled' flag, instead of relying on CR1 EN bit, to keep track of clock being enabled (balanced refcount). Propagate this anywhere else in the driver. Also add 'remove' routine to stop timer and disable clock in case it has been left enabled. Enforce the user interface has been unregistered in the remove routine, before disabling the hardware to avoid possible race. So, remove use of devm_ variant to register triggers and unregister them before the hardware gets disabled [1]. [1] https://patchwork.kernel.org/patch/9956247/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:

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:
