Add the document for ov2640 dt. Cc: devicetree at vger.kernel.org Signed-off-by: Josh Wu <redacted> --- v1 -> v2: 1. change the compatible string to be consistent with verdor file. 2. change the clock and pins' name. 3. add missed pinctrl in example. .../devicetree/bindings/media/i2c/ov2640.txt | 44 ++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/ov2640.txt
