The A33 TCON supports LVDS, so we can toggle the support switch.

The user manual doesn't list the bits for LVDS signal polarity though.
I assume this was verified with the BSP or actual testing? (or rather,

The polarity stuff is a separate series :)
But yeah, both were tested on hardware.
I've applied it, thanks!
