the dma info needs to come in from DT. Besides these are edma
request lines and not sdma.

Isn't l3_gclk that clocks the l3 OCP master port?

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".

Yeah, thats what it looks like to me. l3_gclk is the 200Mhz clock derived from 
core-m4 post divider and l3s_gclk/l4ls_gclk are half of that at 100Mhz, derived
using a fixed divider of 2.
