2 ============================
3
4 The Epson RX6110 can be used with SPI or I2C busses. The kind of
5 bus depends on the SPISEL pin and can not be configured via software.

10 Required properties:
11 - compatible: should be: "epson,rx6110"
12 - reg : the I2C address of the device for I2C
13
14 Example:
15
16 rtc: rtc@32 {
17 compatible = "epson,rx6110"
18 reg = <0x32>;
19 };

22 --------
23
24 Required properties:
25 - compatible: should be: "epson,rx6110"
26 - reg: chip select number
27 - spi-cs-high: RX6110 needs chipselect high
28 - spi-cpha: RX6110 works with SPI shifted clock phase
29 - spi-cpol: RX6110 works with SPI inverse clock polarity
