2022-06-24rtc: Introduce ti-k3-rtcNishanth Menon1-0/+1
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.

2021-12-16rtc: gamecube: Add a RTC driver for the GameCube, Wii and Wii UEmmanuel Gil Peyrot1-0/+1
These three consoles share a device, the MX23L4005, which contains a clock and 64 bytes of SRAM storage, and is exposed on the EXI bus (similar to SPI) on channel 0, device 1. This driver allows it to be used as a Linux RTC device, where time can be read and set. The hardware also exposes two timers, one which shuts down the console and one which powers it on, but these aren’t supported currently. On the Wii U, the counter bias is stored in a XML file, /config/rtc.xml, encrypted in the SLC (eMMC storage), using a proprietary filesystem. In order to avoid having to implement all that, this driver assumes a bootloader will parse this XML file and write the bias into the SRAM, at the same location the other two consoles have it.

2021-08-10rtc: Improve performance of rtc_time64_to_tm(). Add tests.Cassio Neri1-0/+1
The current implementation of rtc_time64_to_tm() contains unnecessary loops, branches and look-up tables. The new one uses an arithmetic-based algorithm appeared in [1] and is approximately 4.3 times faster (YMMV). The drawback is that the new code isn't intuitive and contains many 'magic numbers' (not unusual for this type of algorithm). However, [1] justifies all those numbers and, given this function's history, the code is unlikely to need much maintenance, if any at all. Add a KUnit test case that checks every day in a 160,000 years interval starting on 1970-01-01 against the expected result. Add a new config RTC_LIB_KUNIT_TEST symbol to give the option to run this test suite.

Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory.

2020-03-23rtc: class: support hctosys from modular RTC driversSteve Muckle1-1/+0
Due to distribution constraints it may not be possible to statically compile the required RTC driver into the kernel. Expand RTC_HCTOSYS support to cover all RTC devices (statically compiled or not) by checking at the end of RTC device registration whether the time should be synced.
