Hello, This small series adds support for the RZN1 RTC. Despite its limitations, I found useful to at least have alarm and offset support. The RTC hclk fix has been merged in the renesas-clk-for-v5.19 branch so I dropped it from the series. Cheers, Miquèl Changes in v3: * Collected tags. * s/soc:/clk:/ in the clock commit title. * Dropped the RTC hclk fix which has already been applied. * Added the power-domain properties both in the bindings and in the DT. * Used runtime PM to enable the clock instead of using the clk API directly. Changes in v2: * Fixed the error path in the clk driver, where I missed to release a spin_lock. * Collected tags. * Moved the rtc subnode in the dt to keep the nodes ordered by unit address. * Dropped the useless "oneOf" statement in the bindings (compatible property). * Dropped the start-year property in the bindings (already defined). * Avoided rollover calculations that could be more easily handled (and reviewed) with a time64_t conversion. * Returned ERANGE instead of EOPNOTSUPP when the alarm date is not valid. * Cleared RTC_FEATURE_UPDATE_INTERRUPT to avoid warning from the tools. * Dropped the sysctl patch adding the reset helper, instead fulfilled the description of the RTC clock so that when requesting this clock to be enabled, the idle bit is released. * Avoided rollover calculations that could be more easily handled (and reviewed) with a time64_t conversion. * Fixed the max_range value, after a rtc-range test and looking at other implementations.
