0001 Epson RX6110 Real Time Clock
0002 ============================
0003
0004 The Epson RX6110 can be used with SPI or I2C busses. The kind of
0005 bus depends on the SPISEL pin and can not be configured via software.
0006
0007 I2C mode
0008 --------
0009
0010 Required properties:
0011 - compatible: should be: "epson,rx6110"
0012 - reg : the I2C address of the device for I2C
0013
0014 Example:
0015
0016 rtc: rtc@32 {
0017 compatible = "epson,rx6110"
0018 reg = <0x32>;
0019 };
0020
0021 SPI mode
0022 --------
0023
0024 Required properties:
0025 - compatible: should be: "epson,rx6110"
0026 - reg: chip select number
0027 - spi-cs-high: RX6110 needs chipselect high
0028 - spi-cpha: RX6110 works with SPI shifted clock phase
0029 - spi-cpol: RX6110 works with SPI inverse clock polarity
0030
0031 Example:
0032
0033 rtc: rtc@3 {
0034 compatible = "epson,rx6110"
0035 reg = <3>
0036 spi-cs-high;
0037 spi-cpha;
0038 spi-cpol;
0039 };
