Subject: [PATCH v6 3/5] dt-bindings: display: ti, j721e-dss: Add dt-schema yaml binding
Date: Wed, 15 Jan 2020 13:45:37 +0200 [thread overview]
Message-ID: <313bbd4bef350436d8774141dc09422dd0560691.1579086894.git.jsarha@ti.com> (raw)
In-Reply-To: <cover.1579086894.git.jsarha@ti.com>
Add dt-schema yaml bindig for J721E DSS, J721E version TI Keystone
Display SubSystem.
Version history:
v2: no change
v3: - reg-names: "wp" -> "wb"
- Add ports node
- Add includes to dts example
- reindent dts example
v4: - Add descriptions to reg, clocks, and interrups properties
- Remove minItems when its value is the same as maxItems value
v5: - itemize reg, clocks and interrupts properties' descriptions
- there is no "vp" reg-name, only "wb" for write back
v6: - Add Reviewed-by: from Rob Herring <robh@kernel.org> and
Benoit Parrot <bparrot@ti.com>
