-Epson RX6110 Real Time Clock
-============================
-
-The Epson RX6110 can be used with SPI or I2C busses. The kind of
-bus depends on the SPISEL pin and can not be configured via software.
-
-I2C mode
---------
-
-Required properties:
-  - compatible: should be: "epson,rx6110"
-  - reg : the I2C address of the device for I2C
-
-Example:
-
-	rtc: rtc@32 {
-		compatible = "epson,rx6110"
-		reg = <0x32>;
-	};
-
-SPI mode
---------
-
-Required properties:
-  - compatible: should be: "epson,rx6110"
-  - reg: chip select number
-  - spi-cs-high: RX6110 needs chipselect high
-  - spi-cpha: RX6110 works with SPI shifted clock phase
-  - spi-cpol: RX6110 works with SPI inverse clock polarity
