31 	devices and non-I2C devices, the 'i2c-bus' subnode can be used for
32 	populating I2C devices. If the 'i2c-bus' subnode is present, only
34 	'#address-cells' and '#size-cells' must be defined under this subnode

60 	(i2c-digital-filter). This width is specified in nanoseconds.
62 - i2c-analog-filter-cutoff-frequency
63 	Frequency that the analog filter (i2c-analog-filter) uses to distinguish
66 	a low-pass analog filter). Typical value should be above the normal
67 	i2c bus clock frequency (clock-frequency).
70 - multi-master

75 - pinctrl
79 - scl-gpios
82 - sda-gpios
85 - single-master
88 	Can not be combined with 'multi-master'.

103 	However, flags can be attached to an address. I2C_TEN_BIT_ADDRESS is
104 	used to mark a 10 bit address. It is needed to avoid the ambiguity
105 	between e.g. a 7 bit address of 0x50 and a 10 bit address of 0x050

128 	It can contain any map needing another address than default one.
