Another round of 'allOf' removals that came in this cycle. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org>

The ASPEED USB 2.0 Virtual Hub Controller implements 1 set of USB Hub
|
|
register and several sets of Device and Endpoint registers to support
|
|
the Virtual Hub's downstream USB devices.
|
|
|
|
Supported number of devices and endpoints vary depending on hardware
|
|
revisions. AST2400 and AST2500 Virtual Hub supports 5 downstream devices
|
|
and 15 generic endpoints, while AST2600 Virtual Hub supports 7 downstream
|
|
devices and 21 generic endpoints.
