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.

rtc: gamecube: Add a RTC driver for the GameCube, Wii and Wii U

2021-12-16T09:46:35+00:00

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.
