iio: temperature: tmp006: Add OF device matching support

2023-05-28T19:22:03Z

Adds an of_device_id table entry to the driver, enabling device matching through device tree. With this update, the driver can now match devices using both the i2c_device_id entry and the newly added of_device_id table.

iio: Switch i2c drivers back to use .probe()

2023-05-21T17:54:53Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

iio: temperature: tmp006: Convert to i2c's .probe_new()

2022-11-23T20:20:32Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20221118224540.619276-188-uwe@kleine-koenig.org Signed-off-by: Jonathan Cameron

iio:temperature:tmp006: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() etc

2022-02-18T11:46:03Z

Letting the compiler remove these functions when the kernel is built without CONFIG_PM_SLEEP support is simpler and less error prone than the use of #ifdef based config guards. Removing instances of this approach from IIO also stops them being copied into new drivers.

iio: temperature: tmp006: make sure the chip is powered up in probe

2021-07-19T08:51:59Z

When the device is probed, there's no guarantee that the device is not in power-down mode. This can happen if the driver is unregistered and re-probed. To make sure this doesn't happen, the value of the TMP006_CONFIG register (which is read in the probe function and stored in the device's private data) is being checked to see if the MOD bits have the correct value. This is a fix for a somewhat-rare corner case. As it stands, this doesn't look like a high priority to go into the Fixes route.

iio: temperature: tmp006: convert probe to device-managed

2021-07-19T08:51:59Z

This change converts the driver to register via devm_iio_device_register(). For the tmp006_powerdown() hook, this uses a devm_add_action() hook to put the device in powerdown mode when it's unregistered. With these changes, the remove hook can be removed. The i2c_set_clientdata() call is staying around as the private data is used in the PM routines.

iio: remove explicit IIO device parent assignment

2020-06-14T10:49:59Z

This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment. Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron
