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
Example:
rtc: rtc@3 {
compatible = "epson,rx6110"
reg = <3>
spi-cs-high;
spi-cpha;
spi-cpol;
};
