It turns out it is actually active low as when set to physical level 0 it actually turns the video decoder power off. Without this patch applied: tw9910 0-0045: Product ID error 1f:2 With this patch applied: tw9910 0-0045: tw9910 Product ID b:0 Fixes: commit "186c446f4b840bd77b79d3dc951ca436cb8abe79" Signed-off-by: Jacopo Mondi --- Hi, sending to both media and sh lists, as all previous CEU-related patches went through Hans' tree, even the board specific parts.
