rtc: mt6397: select IRQ_DOMAIN instead of depending on it

2024-03-26T22:20:58+00:00

[ Upstream commit 544c42f798e1651dcb04fb0395219bf0f1c2607e ] IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Relying on it being set for a dependency is risky. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on" for IRQ_DOMAIN to "select" for RTC_DRV_MT6397.

rtc: isl12022: switch to using regmap API

2022-10-12T22:17:22+00:00

The regmap abstraction allows us to avoid the private i2c transfer helpers, and also offers some nice utility functions such as the regmap_update_bits family. While at it, simplify the code even more by not keeping track of ->write_enabled: rtc_set_time is not a hot path, so one extra i2c read doesn't hurt (regmap_update_bits elides the write when the bits are already as desired).

rtc: Introduce ti-k3-rtc

2022-06-24T19:35:31+00:00

Introduce support for Texas Instruments Real Time Clock controller on newer K3 family of SoCs such as AM62x. The hardware module that is being supported is the "digital only" version which doesn't have capability of external wakeup sources and external power backup. However, for many practical applications, this should suffice as RTC is operational across low power sequences. The hardware block by itself is split into two distinct domains internally to further reduce the power consumption with the actual counter block and comparators clocked off a 32k clock source (which based on SoC integration can be sourced by an external crystal) and an register interface block which is driven by the bus clock. While optimal from power perspective, it does create some complicated synchronizations and sequences that one must be wary of in the driver handling.
