dt-bindings: display: ti,k2g-dss: Add dt-schema yaml binding
Add dt-schema yaml bindig for K2G DSS, an ultra-light version of TI Keystone Display SubSystem. Version history: v2: no change v3: - Add ports node - Add includes to dts example - reindent dts example v4: - Add descriptions to reg and clocks properties - Remove minItems when its value is the same as maxItems value - Remove ports node v5: - itemize reg and clocks properties' descriptions v6: - Add Reviewed-by: from Rob Herring <robh@kernel.org> and Benoit Parrot <bparrot@ti.com> v7: no change v8: no change v9: - Remove ports-node from the dts example Signed-off-by: Jyri Sarha <jsarha@ti.com> Reviewed-by: Rob Herring <robh@kernel.org> Reviewed-by: Benoit Parrot <bparrot@ti.com> Link: https://patchwork.freedesktop.org/patch/msgid/270297321f0768c10e241d289e3ac10e39cf12a9.1580129724.git.jsarha@ti.com
