I'm relying on the fact that Ibrahim would have been testing on the other variants through earlier iterations of this series. I've also made a best effort attempt to integrate the MAX31335 support with the more generic code but as the datasheet is not public I can't be sure it's been done correctly and the MAX31335 has definitely not been tested with this updated code (Antoniu if you could test it on your hardware that would really help). changelog: since v6: - Roll changes into max31335 driver that was landed while this was in-flight. - Adjusted code order and variable names to reduce the delta with the max31335 since v5: - change of maintainer - use adi,ti-diode property - deal with oscillator fail and releasing SWRST since v4: - dt-binding: add enum value "2" to aux-voltage-chargable - dt-binding: remove adi,trickle-diode-enable - dt-binding: change description of trickle-resistor-ohms - dt-binding: reorder as in example schema - parse "wakeup-source" when irq not requested - remove limitation on max31328 irq and clockout - remove error and warning messages during trickle charger setup since v3: - dt-binding: remove interrupt names. - dt-binding: add description for "interrupts" property - dt-binding: replace deprecated property "trickle-diode-disable" by "aux-voltage-chargeable" - dt-binding: add new property "adi,trickle-diode-enable" - dt-binding: remove "wakeup-source" - use clear_bit instead of __clear_bit - use devm_of_clk_add_hw_provider instead of of_clk_add_provider - use chip_desc pointer as driver data instead of enum. since v2: - add "break" to fix warning: unannotated fall-through Reported-by: kernel test robot since v1: - dt-binding: update title and description - dt-binding: remove last example - drop watchdog support - support reading 12Hr format instead of forcing 24hr at probe time - use "tm_year % 100" instead of range check - refactor max313xx_init for readability Ibrahim Tilki (2): drivers: rtc: add max313xx series rtc driver dt-bindings: rtc: add max313xx RTCs .../devicetree/bindings/rtc/adi,max31335.yaml | 70 - .../devicetree/bindings/rtc/adi,max313xx.yaml | 167 +++ drivers/rtc/Kconfig | 2 +- drivers/rtc/rtc-max31335.c | 1154 +++++++++++------ 4 files changed, 958 insertions(+), 435 deletions(-) delete mode 100644 Documentation/devicetree/bindings/rtc/adi,max31335.yaml create mode 100644 Documentation/devicetree/bindings/rtc/adi,max313xx.yaml
