From f7b4b54e63643b740c598e044874c4bffa0f04f2 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Fri, 5 Feb 2016 17:09:58 -0200 Subject: [media] tvp5150: add HW input connectors support The tvp5150 decoder has different input connectors. The actual list of HW inputs depends on the device version but all have at least these 3: 1) Composite0 2) Composite1 3) S-Video and some variants have a 4th possible input connector: 4) Signal generator The driver currently uses the .s_routing callback to switch the input connector but since these are separate HW blocks, it's better to use media entities to represent the input connectors and their source pads linked with the decoder's sink pad. This allows user-space to use the MEDIA_IOC_SETUP_LINK ioctl to choose the input connector. For example using the media-ctl user-space tool: $ media-ctl -r -l '"Composite0":0->"tvp5150 1-005c":0[1]' Signed-off-by: Javier Martinez Canillas Signed-off-by: Mauro Carvalho Chehab --- include/dt-bindings/media/tvp5150.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/dt-bindings/media') diff --git a/include/dt-bindings/media/tvp5150.h b/include/dt-bindings/media/tvp5150.h index dc347569854f..d30865222082 100644 --- a/include/dt-bindings/media/tvp5150.h +++ b/include/dt-bindings/media/tvp5150.h @@ -27,6 +27,8 @@ #define TVP5150_SVIDEO 2 #define TVP5150_GENERATOR 3 +#define TVP5150_INPUT_NUM 4 + /* TVP5150 HW outputs */ #define TVP5150_NORMAL 0 #define TVP5150_BLACK_SCREEN 1 -- cgit v1.2.3
