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: mt6397: Remove unused member dev

2020-10-15T10:01:29Z

Removing the struct member "dev" in mt6397 RTC driver because it's not initialized and the only usage is for one debugging message. Also fixed a typo in the error message.

rtc: mt6397: Add support for the MediaTek MT6358 RTC

2020-05-21T07:55:48Z

This add support for the MediaTek MT6358 RTC. Driver using compatible data to store different RTC_WRTGR address offset. This replace RTC_WRTGR to RTC_WRTGR_MT6323 in mt6323-poweroff driver which only needed by armv7 CPU without ATF.

Pull RTC updates from Alexandre Belloni: "The VL_READ and VL_CLR ioctls have been reworked to be more useful. This will not break userspace as there are very few users and they are using the integer value as a boolean. Apart from that, two drivers were reworked and a few fixes here and there for a net reduction of number of lines. Summary: Subsystem: - the VL_READ and VL_CLR ioctls are now documented and their behavior is unified across all the drivers. - RTC_I2C_AND_SPI Kconfig option rework to avoid selecting both REGMAP_I2C and REGMAP_SPI unecessarily. Drivers: - at91rm9200: remove deprecated procfs, add sam9x60, sama5d4 and sama5d2 compatibles. - cmos: solve lost interrupts issue on MS Surface 3 - hym8563: return proper errno when time is invalid - rv3029: many fixes, nvram support" * tag 'rtc-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (63 commits) dt-bindings: rtc: at91rm9200: document clocks property rtc: i2c/spi: Avoid inclusion of REGMAP support when not needed rtc: Kconfig: select REGMAP_I2C when necessary rtc: Kconfig: properly indent sd3078 entry rtc: cmos: Refactor code by using the new dmi_get_bios_year() helper rtc: cmos: Use predefined value for RTC IRQ on legacy x86 rtc: cmos: Stop using shared IRQ rtc: tps6586x: Use IRQ_NOAUTOEN flag rtc: at91rm9200: use FIELD_PREP/FIELD_GET rtc: at91rm9200: avoid time readout in at91_rtc_setalarm rtc: at91rm9200: move register definitions to C file rtc: at91rm9200: add sama5d4 and sama5d2 compatibles dt-bindings: rtc: at91rm9200: convert bindings to json-schema rtc: at91rm9200: remove procfs information dt-bindings: atmel, at91rm9200-rtc: add microchip, sam9x60-rtc rtc: pcf8563: Use BIT rtc: moxart: Convert to SPDX identifier rtc: ds1343: Remove unused struct spi_device in struct ds1343_priv rtc: rx8025: Remove struct i2c_client from struct rx8025_data rtc: hym8563: Read the valid flag directly instead of caching it ...

rtc: mt6397: drop free_irq of devm_ allocated irq

2019-12-10T13:25:34Z

The devm_request_threaded_irq function allocates irq that is released when a driver detaches. Thus, there is no reason to explicitly call free_irq in probe function.
