Subject: [PATCH] media: adv7180: Nasty hack to allow input selection.
|
|
|
|
Whilst the adv7180 driver support s_routing, nothing else
|
|
does, and there is a missing lump of framework code to
|
|
define the mapping from connectors on a board to the inputs
|
|
they represent on the ADV7180.
|
|
|
|
Add a nasty hack to take a module parameter that is passed in
|
|
to s_routing on any call to G_STD, or S_STD (or subdev
|
|
g_input_status call).
