I took a closer look at this while preparing to merge it and it adds a
bunch of sparse warnings:

It's also missing the one-line comments above each OCP interface record,
e.g.
/* l4_per1 -> gpio6 */
and a few other hwmod comments. I've added those too.
By courtesy, I've fixed these issues for this patch. But in the future,
please check your patches before sending to make sure that they don't add
new sparse warnings. If you need help running sparse, let us know (or
Nishanth can probably help you out; I think he's got some scripts that
test patch sets for common pre-submission problems). And please try to
align with the comment style of the rest of the hwmod files.

Subject: [PATCH] ARM: OMAP2+: DRA7: Add hwmod entries for PWMSS
Add hwmod entries for the PWMSS on DRA7.
Set l4_root_clk_div as the main_clk of PWMSS. It is fixed-factored clock
equal to L4PER2_L3_GICLK/2(l3_iclk_div/2).
