Hey Harry,
I can't say much about the overall changes (DAL/DC is a large code base and I've
no deep understanding of it), but I noticed a couple of things regarding
readability, see below.

Can these be aligned like a table? For example like:
static struct state_dependent_clocks dce112_max_clks_by_state[] = {
{ .display_clk_khz = 0, .pixel_clk_khz = 0 },
{ .display_clk_khz = 389189, .pixel_clk_khz = 346672 },
{ .display_clk_khz = 459000, .pixel_clk_khz = 400000 },
{ .display_clk_khz = 667000, .pixel_clk_khz = 600000 },
{ .display_clk_khz = 1132000, .pixel_clk_khz = 600000 },
};
Bonus points, if you make the alignment match across all of these structs. ;-)

Is it guaranteed, that div_range is not a null pointer? This is a common
question and applies to the functions below as well. I expected an
if(!div_range)

I'd be nice if you used only one opening and one closing statement for the
comment. You can always add a asterisk to the front:
/*
* Multi-line
* comment here
*/
It really took me a while to parse the comment – especially since there are
sometimes spaces between the closing statement and sometimes not.

Can you document why 62? Maybe a speaking #define would be best?
