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:

Add suspend and resume operations for being used by optional power management. The suspend function is switching off an GPIO which can be used by the hardware to switch power off. The resume function is switching the GPIO on and sleeps an adjustable time to give the device a chance to be up and running. If activated the driver gets into autosuspend after some time of inactivity. Suggested-by:

This driver handles two different Sharp sensors that have been proposed for merging to the mainline kernel over the years, and already has a limited proximity-only driver in the input subsystem. These components are completely different from the confusingly similarly named Sharp GP2AP020A00F, for which we have a driver in drivers/iio/light/gp2ap020a00f.c The two components GP2AP002A00F and GP2AP002S00F are distinctively different but similar: they share the same set of registers but differ slightly in the I2C protocol. Instead of the approach by the previous input driver, we create a combined IIO proximity and light sensor driver. The plan is to merge this driver and delete the input driver. The pieces for the driver are picked all over the place after researching and grepping through a few different vendor trees and driver submissions. We merge it under the light sensors because: - It has similarities with the Capella CM3605 light sensor and proximity driver which is there. - It is related to the GP2AP020A00F driver which is also there. This driver was tested with the Samsung GT-S7710 mobile phone which has the GP2AP002S00F proximity sensor mounted. The suspend/resume cycle will disable the interrupt from the sensor. If someone would desire to use this interrupt for wakeup, the driver will need modifications.
