This adds support for EPSON TOYOCOM RTC-7301SF/DG which has parallel interface compatible with SRAM. This driver supports basic clock, calendar and alarm functionality. Tested with Microblaze linux running on Artix7 FPGA board with my own custom IP for RTC-7301.

Required properties:
|
|
|

|
|
rtc: rtc@44a00000 {
|
|
compatible = "epson,rtc7301dg";
|
|
reg = <0x44a00000 0x10000>;
|
|
interrupt-parent = <&axi_intc_0>;
|
|
interrupts = <3 2>;
|
|
};
