Merge remote branch 'origin' into secretlab/next-devicetree
Merging in current state of Linus' tree to deal with merge conflicts and build failures in vio.c after merge. Conflicts: drivers/i2c/busses/i2c-cpm.c drivers/i2c/busses/i2c-mpc.c drivers/net/gianfar.c Also fixed up one line in arch/powerpc/kernel/vio.c to use the correct node pointer. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

+/**
+ * struct caif_dev_common - data shared between CAIF drivers and stack.
+ * @flowctrl: Flow Control callback function. This function is
+ * supplied by CAIF Core Stack and is used by CAIF
+ * Link Layer to send flow-stop to CAIF Core.
+ * The flow information will be distributed to all
+ * clients of CAIF.
+ *
+ * @link_select: Profile of device, either high-bandwidth or
+ * low-latency. This member is set by CAIF Link
+ * Layer Device in order to indicate if this device
+ * is a high bandwidth or low latency device.
+ *
+ * @use_frag: CAIF Frames may be fragmented.
+ * Is set by CAIF Link Layer in order to indicate if the
+ * interface receives fragmented frames that must be
+ * assembled by CAIF Core Layer.
+ *
+ * @use_fcs: Indicate if Frame CheckSum (fcs) is used.
+ * Is set if the physical interface is
+ * using Frame Checksum on the CAIF Frames.
+ *
+ * @use_stx: Indicate STart of frame eXtension (stx) in use.
+ * Is set if the CAIF Link Layer expects
+ * CAIF Frames to start with the STX byte.
+ *
+ * This structure is shared between the CAIF drivers and the CAIF stack.
+ * It is used by the device to register its behavior.
+ * CAIF Core layer must set the member flowctrl in order to supply
+ * CAIF Link Layer with the flow control function.
