Right, the sdma information is not needed anymore.

Hmm, possibly... dispc_clk looks a bit odd there. It's been very
difficult to figure out things like that, with the not-so-good am43xx
documentation.
The documentation mentions "L3 Fast Interconnect" and "LCDL3OCPIFCLK"
related to DSS's OCP master, but searching for those in the TRM doesn't
reveal much.
Would the l3_gclk match the "L3 Fast Interconnect" and l3s_gclk match
the "L3 Slow Interconnect".
