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;
|
|
};
