|
|
|
|
|
|
|
|
Required properties :
|
|
|
|
|
|
|
|
|
|
- reg : Offset and length of the register set for the device
|
2013-07-24 07:14:35 +00:00
|
|
|
- compatible : Should be "marvell,mv64xxx-i2c" or "allwinner,sun4i-i2c"

or "marvell,mv78230-i2c" or "marvell,mv78230-a0-i2c"
|
|
|
|
|
Note: Only use "marvell,mv78230-a0-i2c" for a very rare,
|
|
|
|
|
initial version of the SoC which had broken offload
|
|
|
|
|
support. Linux auto-detects this and sets it
|
|
|
|
|
appropriately.
