1 Chrome OS CROS_EC Binding
4 The device tree node which describes the operation of the CROS_EC interface
8 - compatible = "google,cros-ec"
11 - spi-max-frequency : Sets the maximum frequency (in Hz) for SPI bus
13 - i2c-max-frequency : Sets the maximum frequency (in Hz) for I2C bus
15 - ec-interrupt : Selects the EC interrupt, defined as a GPIO according
17 - optimise-flash-write : Boolean property - if present then flash blocks
18 containing all 0xff will not be written, since we assume that the EC
19 uses that pattern for erased blocks
21 The CROS_EC node should appear as a subnode of the interrupt that connects it
22 to the EC (e.g. i2c, spi, lpc). The reg property (as usual) will indicate
23 the unit address on that bus.
