We have three rotation methods supported by the SoCs with DSS: DMA,

DMA rotation works in theory on all DSS platforms, but in practice it's
unusable due to the huge amount of memory bandwidth it uses, and has
never really been used.
VRFB is available on OMAP3, but is not supported by omapdrm, even though
we have some code for it in the dispc driver.
TILER is supported on OMAP4/OMAP5/DRA7/AM5 platforms, but has some

DSS uses "replication logic" to convert color components from smaller
bit widths to bigger bit widths. Without replication logic, the color
component would be shifted and the least significant bits would be left
at 0, whereas with replication logic, the least significat bits will be
filled with the most significant bit.
For some reason omapdrm leaves replication logic always to off, which,
in the most common case, means that showing 16-bit RGB colors on 24-bit
display gives a bit darker colors than expected.
The reset value of the replication logic bit is enabled, and it should
always be set, as there's no practical reason to disable it. This patch
removes the option to disable it from omapdrm, and always sets it to
enabled in dispc.
