1*c66ec88fSEmmanuel Vadot* AT86RF230 IEEE 802.15.4 *
2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotRequired properties:
4*c66ec88fSEmmanuel Vadot  - compatible:		should be "atmel,at86rf230", "atmel,at86rf231",
5*c66ec88fSEmmanuel Vadot			"atmel,at86rf233" or "atmel,at86rf212"
6*c66ec88fSEmmanuel Vadot  - spi-max-frequency:	maximal bus speed, should be set to 7500000 depends
7*c66ec88fSEmmanuel Vadot			sync or async operation mode
8*c66ec88fSEmmanuel Vadot  - reg:		the chipselect index
9*c66ec88fSEmmanuel Vadot  - interrupts:		the interrupt generated by the device. Non high-level
10*c66ec88fSEmmanuel Vadot			can occur deadlocks while handling isr.
11*c66ec88fSEmmanuel Vadot
12*c66ec88fSEmmanuel VadotOptional properties:
13*c66ec88fSEmmanuel Vadot  - reset-gpio:		GPIO spec for the rstn pin
14*c66ec88fSEmmanuel Vadot  - sleep-gpio:		GPIO spec for the slp_tr pin
15*c66ec88fSEmmanuel Vadot  - xtal-trim:		u8 value for fine tuning the internal capacitance
16*c66ec88fSEmmanuel Vadot			arrays of xtal pins: 0 = +0 pF, 0xf = +4.5 pF
