rtc: pcf2123: 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/20230123200217.1236011-5-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: pcf2123: set RTC_FEATURE_ALARM_RES_MINUTE

2022-03-23T18:58:39Z

Alarms have a resolution of a minute. Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20220309162301.61679-9-alexandre.belloni@bootlin.com

rtc: pcf2123: switch to RTC_FEATURE_UPDATE_INTERRUPT

2022-03-23T18:58:39Z

Stop using uie_unsupported and clear RTC_FEATURE_UPDATE_INTERRUPT instead. Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20220309162301.61679-8-alexandre.belloni@bootlin.com

rtc: pcf2123: Add SPI ID table

2021-09-25T21:22:28Z

Currently autoloading for SPI devices does not use the DT ID table, it uses SPI modalises. Supporting OF modalises is going to be difficult if not impractical, an attempt was made but has been reverted, so ensure that module autoloading works for this driver by adding an id_table listing the SPI IDs for everything.

rtc: pcf2123: use rtc_lock/rtc_unlock

2021-01-25T22:46:17Z

Avoid accessing directly rtc->ops_lock and use the RTC core helpers. Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20210119220653.677750-10-alexandre.belloni@bootlin.com

rtc: rework rtc_register_device() resource management

2020-11-19T11:50:12Z

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: pcf2123: add proper compatible string

2019-08-20T19:42:19Z

nxp,rtc-pcf2123 is not a proper compatible strong for this RTC. The part name is only pcf2123 and is less confusing. Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20190819182656.29744-9-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: pcf2123: let the core handle range offsetting

2019-08-20T19:42:17Z

Set the RTC range properly and use the core windowing and offsetting to (unfortunately) map back to a 1970-2069 range. Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20190819182656.29744-8-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: pcf2123: convert to devm_rtc_allocate_device

2019-08-20T19:42:15Z

This allows further improvement of the driver. Also remove the unecessary error string as the core will already display error messages. Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20190819182656.29744-7-alexandre.belloni@bootlin.com Signed-off-by: Alexandre Belloni

rtc: pcf2123: remove useless error path goto

2019-08-20T19:42:13Z

kfree_exit only returns ret, remove it. This also fixes the devm_regmap_init_spi error case where the probe wouldn't actually fail because ret is initialized to 0.
