Merge char-misc-next into staging-next 

This resolves the merge issues and confusions people were having with
the goldfish drivers due to changes for them showing up in two different
trees.

EEPROMs (SPI) compatible with Microchip Technology 93xx46 family.
Required properties:
- compatible : shall be one of:
"atmel,at93c46d"
"eeprom-93xx46"
- data-size : number of data bits per word (either 8 or 16)
Optional properties:
- read-only : parameter-less property which disables writes to the EEPROM
- select-gpios : if present, specifies the GPIO that will be asserted prior to
each access to the EEPROM (e.g. for SPI bus multiplexing)
Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt
apply. In particular, "reg" and "spi-max-frequency" properties must be given.
Example:
eeprom@0 {
compatible = "eeprom-93xx46";
reg = <0>;
spi-max-frequency = <1000000>;

in the kernel is used to access virtio rings from the host. The card
VOP driver allows card virtio drivers to communicate with their user
