Hi Alessandro / Alexandre, Here's the V2 of a previous patchset I sent back in April. Patch [1/4] was updated with Krzysztof's feedback. Patches 2-4 are unmodified from V1 as they didn't receive any feedback. Patch 4 is RFC; I *think* it works, but I don't know how to test it. V1 had a 5th patch which would reset the scratchpad register on power loss, but was dropped following upstream feedback. Cheers, - Paul Paul Cercueil (4): dt-bindings: rtc: ingenic: Rework compatible strings and add #clock-cells rtc: jz4740: Use readl_poll_timeout rtc: jz4740: Register clock provider for the CLK32K pin rtc: jz4740: Support for fine-tuning the RTC clock .../devicetree/bindings/rtc/ingenic,rtc.yaml | 32 ++++- drivers/rtc/rtc-jz4740.c | 113 +++++++++++++++--- 2 files changed, 129 insertions(+), 16 deletions(-) -- 2.35.1
