Subject: [PATCH v3 0/4] eeprom: ee1004: Enable devices on multiple busses

The driver previously prevented probing devices on more than one
bus due to locking constraints with the special page addresses. This
constraint can be removed by allocating a reference-counted bus
structure containing the lock, rather than using global variables.
In addition, add devicetree bindings for the EE1004 driver for the
AT30TSE device and add the devices to the Bonnell BMC system.

Changes since v2:
 - Remove of_device.h include
 - Use the full model number of the device for the binding
 - Fix commit name for the bindings documentation and the
   OF matching support

Changes since v1:
 - Add the devicetree changes
