2023-07-27rtc: Explicitly include correct DT includesRob Herring1-1/+1
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-06-06rtc: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
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.

Statically allocated array of pointers to hwmon_channel_info can be made const for safety.

The RV-3032 has been assigned the MCRY3032 ACPI ID. Link: https://lore.kernel.org/r/20230214202716.565749-1-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
2023-02-01rtc: rv3032: use IRQ flags obtained from fwnodeAlexandre Belloni1-1/+6
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.

2021-10-18rtc: rv3032: allow setting BSMAlexandre Belloni1-0/+76
Backup Switch Mode is currently set properly when the trickle charger is enabled. However, in the case of a non-rechargeable battery, it is necessary to be able to enable it, only allow that when the trickle charger is disabled.

2020-11-19rtc: rework rtc_register_device() resource managementBartosz Golaszewski1-1/+1
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.

2020-11-19rtc: add devm_ prefix to rtc_nvmem_register()Bartosz Golaszewski1-2/+2
rtc_nvmem_register() is a managed interface. It doesn't require any release function to be called at driver detach. To avoid confusing driver authors, let's rename it to devm_rtc_nvmem_register() and add it to the list of managed interfaces in Documentation/.
