1 Generic device tree bindings for I2C busses
4 This document describes generic bindings which can be used to describe I2C
12 - compatible      - name of I2C bus controller
17 The cells properties above define that an address of children of an I2C bus
29 - i2c-bus
30 	For I2C adapters that have child nodes that are a mixture of both I2C
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
33 	subnodes of this will be considered as I2C slaves. The properties,
37 - i2c-scl-falling-time-ns
38 	Number of nanoseconds the SCL signal takes to fall; t(f) in the I2C
41 - i2c-scl-internal-delay-ns
44 - i2c-scl-rising-time-ns
45 	Number of nanoseconds the SCL signal takes to rise; t(r) in the I2C
48 - i2c-sda-falling-time-ns
49 	Number of nanoseconds the SDA signal takes to fall; t(f) in the I2C
52 - i2c-analog-filter
53 	Enable analog filter for i2c lines.
55 - i2c-digital-filter
56 	Enable digital filter for i2c lines.
58 - i2c-digital-filter-width-ns
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
67 	i2c bus clock frequency (clock-frequency).
100 	MCTP over I2C transport.
106 	name of I2C slave device
109 	One or many I2C slave addresses. These are usually a 7 bit addresses.
130 	"irq", "wakeup" and "smbus_alert" names are recognized by I2C core,
141 used by the device. I2C core will assign "irq" interrupt (or the very first
145 adapters that support this feature, may use "host-notify" property. I2C
149 Also, if device is marked as a wakeup source, I2C core will set up "wakeup"
