[ Upstream commit 62b143b5ec4a14e1ae0dede5aabaf1832e3b0073 ]
It turns out that I had misconfigured the device I was using the panel with; the bus data polarity is not high for this panel, I had to change the config on the display controller's side.
Fix the panel config to properly reflect its accurate settings.
