This patch set aims to add support for EPSON RX-8571 real-time clock.
EPSON RX-8571 rtc is compatible with EPSON RX-8581 rtc except that
former has 16 bytes additional RAM.
1 byte of nvmem is supported on both RX-8581 and RX-8571. It is
exposed through sysfs along with support for 16 bytes additional RAM
present only on EPSON RX-8571.
This patch series is tested against renesas-dev and linux-next.
