From e69595170b1cad850b5076656b2e1542f3eb2437 Mon Sep 17 00:00:00 2001 From: Kieran Bingham Date: Thu, 6 Jul 2017 07:01:15 -0400 Subject: [PATCH] media: adv748x: Add adv7481, adv7482 bindings Create device tree bindings documentation for the ADV748x. The ADV748x supports both the ADV7481 and ADV7482 chips which provide analogue decoding and HDMI receiving capabilities Signed-off-by: Kieran Bingham Reviewed-by: Laurent Pinchart Acked-by: Rob Herring Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- .../devicetree/bindings/media/i2c/adv748x.txt | 95 +++++++++++++++++++ 1 file changed, 95 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/adv748x.txt diff --git a/Documentation/devicetree/bindings/media/i2c/adv748x.txt b/Documentation/devicetree/bindings/media/i2c/adv748x.txt new file mode 100644 index 000000000000..21ffb5ed8183 --- /dev/null +++ b/Documentation/devicetree/bindings/media/i2c/adv748x.txt @@ -0,0 +1,95 @@ +* Analog Devices ADV748X video decoder with HDMI receiver + +The ADV7481 and ADV7482 are multi format video decoders with an integrated +HDMI receiver.
