1 * Maxim/Dallas Semiconductor DS-1302 RTC
5 The device uses the standard MicroWire half-duplex transfer timing.
12 - compatible : Should be "maxim,ds1302"
14 Required SPI properties:
16 - reg : Should be address of the device chip select within
19 - spi-max-frequency : DS-1302 has 500 kHz if powered at 2.2V,
22 - spi-3wire : The device has a shared signal IN/OUT line.
24 - spi-lsb-first : DS-1302 requires least significant bit first
27 - spi-cs-high: DS-1302 has active high chip select line. This is
