Rob,
As promissed, this patch converts the spmi.txt generic bus bindings to
html.

-System Power Management Interface (SPMI) Controller
-
-This document defines a generic set of bindings for use by SPMI controllers. A
-controller is modelled in device tree as a node with zero or more child nodes,
-each representing a unique slave on the bus.
-
-Required properties:
-- #address-cells : must be set to 2
-- #size-cells : must be set to 0
-
-Child nodes:
-
-An SPMI controller node can contain zero or more child nodes representing slave
-devices on the bus. Child 'reg' properties are specified as an address, type
-pair. The address must be in the range 0-15 (4 bits). The type must be one of
-SPMI_USID (0) or SPMI_GSID (1) for Unique Slave ID or Group Slave ID respectively.
-These are the identifiers "statically assigned by the system integrator", as
-per the SPMI spec.
-
-Each child node must have one and only one 'reg' entry of type SPMI_USID.

+description: |
+ The System Power Management (SPMI) controller is a 2-wire bus defined
+ by the MIPI Alliance for power management control to be used on SoC designs.
+
+ SPMI controllers are modelled in device tree using a generic set of
+ bindings defined here, plus any bus controller specific properties, if
+ needed.
+
+ Each SPMI controller has zero or more child nodes (up to 16 ones), each
+ one representing an unique slave at the bus.
