rtc: ab-eoz9: don't fail temperature reads on undervoltage notification

2024-11-25T22:34:12+00:00

The undervoltage flags reported by the RTC are useful to know if the time and date are reliable after a reboot. Although the threshold VLOW1 indicates that the thermometer has been shutdown and time compensation is off, it doesn't mean that the temperature readout is currently impossible. As the system is running, the RTC voltage is now fully established and we can read the temperature.

rtc: ab-eoz9: fix abeoz9_rtc_read_alarm

2024-11-18T11:14:37+00:00

abeoz9_rtc_read_alarm assumes we always read the alarm in 12-hour mode while abeoz9_rtc_set_alarm will always set it in 24-hour mode. We could support 12-hour mode in both functions but it seems very unlikely that the RTC would be set to 12-hour mode now as the driver has been setting it to 24-hour mode for a while now. The setting is undefined at power-up and unchanged by subsequent resets which doesn't help us.

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: ab-eoz9: use IRQ flags obtained from fwnode

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/20230123200217.1236011-2-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: use simple i2c probe

2022-06-24T19:24:02+00:00

All these drivers have an i2c probe function which doesn't use the "struct i2c_device_id *id" parameter, so they can trivially be converted to the "probe_new" style of probe with a single argument. This change was done using the following Coccinelle script, and fixed up for whitespace changes: @ rule1 @ identifier fn; identifier client, id; @@ - static int fn(struct i2c_client *client, const struct i2c_device_id *id) + static int fn(struct i2c_client *client) { ...when != id } @ rule2 depends on rule1 @ identifier rule1.fn; identifier driver; @@ struct i2c_driver driver = { - .probe + .probe_new = ( fn | - &fn + fn ) , }; Signed-off-by: Stephen Kitt Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20220610162346.4134094-1-steve@sk2.org
