1 | Epson RX6110 Real Time Clock |
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. | |
6 | ||
7 | I2C mode | |
8 | -------- | |
9 | ||
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 | }; | |
20 | ||
21 | SPI mode | |
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 | |
30 | ||
31 | Example: | |
32 | ||
33 | rtc: rtc@3 { | |
34 | compatible = "epson,rx6110" | |
35 | reg = <3> | |
36 | spi-cs-high; | |
37 | spi-cpha; | |
38 | spi-cpol; | |
39 | }; |
