| ImgTec Serial Control Protocol (SCB) I2C Controller: |
| |
| Required properties: |
| - compatible : Must be "img,scb"; |
| - reg |
| - interrupts |
| - clocks : A reference to the SCB clock node; |
| - bit-rate : Speed of bus in Hz; |
| - bus-delay : Bus delay in ms; |
| - quirks : Quirks present on the hardware: |
| - 0x00000001 : write read fence. |
| 2 writes required to ensure subsequent read reflects the |
| effects of a prior write, due to clock domain crossing problem. |
| - 0x00000002 : atomic mode only. |
| Automatic mode unreliable when using different clock domain for |
| data clock. This can be worked around by forcing atomic mode |
| only with this quirk (slower), or using the same clock domain. |
| - #address-cells = <1>; |
| - #size-cells = <0>; |
| |
| Optional properties: |
| - pinctrl-names : Can contain "default" |
| - pinctrl-0 : Pin control maps for when enabled |
| - linux,i2c-index: Can be used to override the I2C bus number. This is useful |
| when some of the I2C adapters are used by other non-Linux cores so would get |
| numbered incorrectly by default. |
| - Child nodes conforming to i2c bus binding |
