rtc: Explicitly include correct DT includes

2023-07-27T21:31:29Z

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.

rtc: pcf85063: Drop enum pcf85063_type and split pcf85063_cfg[]

2023-07-27T21:07:50Z

Drop enum pcf85063_type and split the array pcf85063_cfg[] as individual variables, and make lines shorter by referring to e.g. &pcf85063_cfg instead of &pcf85063_cfg[PCF85063].

rtc: pcf85063: Simplify probe()

2023-07-27T21:07:50Z

The pcf85063_ids[].driver_data could store a pointer to the config, like for DT-based matching, making I2C and DT-based matching more similar. After that, we can simplify the probe() by replacing of_device_get_ match_data() and i2c_match_id() by i2c_get_match_data() as we have similar I2C and DT-based matching table.

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

2023-06-06T21:29:37Z

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: pcf85063: use IRQ flags obtained from fwnode

2023-02-01T08:13:35Z

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/20230123200217.1236011-6-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: pcf85063: Fix reading alarm

2022-11-16T22:22:38Z

If the alarms are disabled the topmost bit (AEN_*) is set in the alarm registers. This is also interpreted in BCD number leading to this warning: rtc rtc0: invalid alarm value: 2022-09-21T80:80:80 Fix this by masking alarm enabling and reserved bits.

The PCF85063 doesn't support UIE because setting an alarm to fire every second confuses the chip and the fastest we can go is an alarm every 2 seconds. Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20220309162301.61679-13-alexandre.belloni@bootlin.com
