rtc: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-07-06T22:40:29+00:00

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove a comma after the sentinel entry in rtc-hym8563.

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

2023-06-06T21:29:37+00:00

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.

rtc: rx8010: use IRQ flags obtained from fwnode

2023-02-01T08:13:35+00:00

Allow the IRQ type to be passed from the device tree if available as there may be components changing the trigger type of the interrupt between the RTC and the IRQ controller. Link: https://lore.kernel.org/r/20230123200217.1236011-1-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: rx8010: use rtc_lock/rtc_unlock

Avoid accessing directly rtc->ops_lock and use the RTC core helpers. Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20210119220653.677750-12-alexandre.belloni@bootlin.com

rtc: rx8010: drop a struct rtc_class_ops

rtc: rework rtc_register_device() resource management

2020-11-19T11:50:12+00:00

rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.

rtc: rx8010: rename rx8010_init_client() to rx8010_init()

2020-09-29T20:18:10+00:00

Since the switch to using regmap this function no longer takes the I2C client struct as argument nor do we even interact with the client anywhere other than when creating the regmap. Rename it to a less misleading name: "rx8010_init()". Signed-off-by: Bartosz Golaszewski Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20200917114656.9036-1-brgl@bgdev.pl

rtc: rx8010: use range checking provided by core RTC code

We don't need to check the time range manually in set_time(), we can use range_min and range_max exposed by struct rtc_device. Signed-off-by: Bartosz Golaszewski Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20200914154601.32245-15-brgl@bgdev.pl

rtc: rx8010: convert to using regmap

2020-09-15T08:50:38+00:00

This driver requires SMBUS to work. We can relax this requirement if we switch to using i2c regmap and let the regmap sub-system figure out how to talk to the bus. This also has the advantage of shrinking the code for register updates.
