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 Signed-off-by: Jyri Sarha <jsarha@ti.com> --- .../bindings/display/ti/ti,k2g-dss.yaml | 109 ++++++++++++++++++ 1 file changed, 109 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/ti/ti,k2g-dss.yaml -- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki.
