Gregory CLEMENT 34f54f579a rtc: armada38x: Add support for Armada 7K/8K
The Armada 7K/8K use the same RTC IP than the Armada 38x. However the SOC
integration differs in 2 points:
 - MBUS bridge timing initialization
 - IRQ configuration at SoC level

Moreover the Armada 7K/8K have an issue preventing to get the interrupt
from alarm 1. This commit allows to use alarm 2 for these A7K/8K but to
still use alarm 1 for the Armada 38x.

* Real Time Clock of the Armada 38x/7K/8K SoCs
RTC controller for the Armada 38x, 7K and 8K SoCs
Required properties:
- compatible : Should be one of the following:
"marvell,armada-380-rtc" for Armada 38x SoC
"marvell,armada-8k-rtc" for Aramda 7K/8K SoCs
- reg: a list of base address and size pairs, one for each entry in
reg-names
- reg names: should contain:
* "rtc" for the RTC registers
* "rtc-soc" for the SoC related registers and among them the one
related to the interrupt.
- interrupts: IRQ line for the RTC.
Example:
rtc@a3800 {
compatible = "marvell,armada-380-rtc";
reg = <0xa3800 0x20>, <0x184a0 0x0c>;
reg-names = "rtc", "rtc-soc";
interrupts = <GIC_SPI 21 IRQ_TYPE_LEVEL_HIGH>;
};
