This is the third amlogic driver. The RTC hardware of A4 SoC is different

function is using the system clock to implement a virtual alarm. Add

alarm capabilities, clock error correction capabilities. It can generate
alarm, period, carry interrupts.

Add a driver for RTCA-3 IP. The driver implements calendar count mode (as
the conversion b/w RTC and system time is simpler, done with bcd2bin(),
bin2bcd()), read and set time, read and set alarm, read and set
an offset.

rtc: Introduce ti-k3-rtc

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.
