Subject: [PATCH] of: Fix kerneldoc output formatting
The indentation of the kerneldoc comments affects the output formatting.
Leading tabs in particular don't work, sections need to be indented
under the section header, and several code blocks are reformatted.

Subject: [PATCH] of: Add missing 'Return' section in kerneldoc comments
Many of the DT kerneldoc comments are lacking a 'Return' section. Let's
add the section in cases we have a description of return values. There's
still some cases where the return values are not documented.

Subject: [PATCH] of: base: add of_parse_phandle_with_optional_args()
Add a new variant of the of_parse_phandle_with_args() which treats the
cells name as optional. If it's missing, it is assumed that the phandle
has no arguments.
Up until now, a nvmem node didn't have any arguments, so all the device
trees haven't any '#*-cells' property. But there is a need for an
additional argument for the phandle, for which we need a '#*-cells'
property. Therefore, we need to support nvmem nodes with and without
this property.

Subject: [PATCH] of: property: make #.*-cells optional for simple props
Sometimes, future bindings for phandles will get additional arguments.
Thus the target node of the phandle will need a new #.*-cells property.
To be backwards compatible, this needs to be optional.
Prepare the DEFINE_SIMPLE_PROPS() to handle the cells name as optional.

Subject: [PATCH] of: base: add of_parse_phandle_with_optional_args()
Add a new variant of the of_parse_phandle_with_args() which treats the
cells name as optional. If it's missing, it is assumed that the phandle
has no arguments.
Up until now, a nvmem node didn't have any arguments, so all the device
trees haven't any '#*-cells' property. But there is a need for an
additional argument for the phandle, for which we need a '#*-cells'
property. Therefore, we need to support nvmem nodes with and without
this property.

Subject: [PATCH] of: property: make #.*-cells optional for simple props
Sometimes, future bindings for phandles will get additional arguments.
Thus the target node of the phandle will need a new #.*-cells property.
To be backwards compatible, this needs to be optional.
Prepare the DEFINE_SIMPLE_PROPS() to handle the cells name as optional.
