| description: | |
| This option is used when the I2C target is enabled and it can support |
| buffered mode for I2C target transfer. When 'false', the target will use |
| PIO (Programmed I/O) mode. |
| forwards: |
| type: phandle-array |
| description: | |
| When added, read/write requests sent to this bus for a given address will |
| be forwarded to the specified phandle (must be another i2c bus). As an |
| example, if we wanted to forward any requests from i2c0@0x20 to i2c1, we |
| would use: |
| |
| &i2c0 { |
| forward = <&i2c1 0x20>; |
| }; |
