Subject: [PATCH] drm/vc4: hdmi: Use full range helper in csc functions
|
|
|
|
The CSC callbacks takes a boolean as an argument to tell whether we're
|
|
using the full range or limited range RGB.
|
|
|
|
However, with the upcoming YUV support, the logic will be a bit more
|
|
complex. In order to address this, let's make the callbacks take the
|
|
entire mode, and call our new helper to tell whether the full or limited
|
|
range RGB should be used.
