For the OCP if part, I think that is still needed until we switch over to
full sysc driver. clkctrl_offs you probably also need because that is used
for mapping the omap_hwmod against a specific clkctrl clock. Those can be
only removed once we are done with hwmod (or figure out some other way to
assign the clkctrl clock to a hwmod.)
Hmm might be worth testing. I thought your commit 70f05be32133
("ARM: OMAP2+: hwmod: populate clkctrl clocks for hwmods if available")
already parses the clkctrl from dts?
It maps the clkctrl clock to be used by hwmod, if those are available.
We didn't add any specific clock entries to DT for mapping the actual
clkctrl clock without the hwmod_data hints yet though, as that was
deemed temporary solution only due to transition to interconnect driver.
I.e., you would need something like this in DT for every device node:
&uart3 {
clocks = <l4per_clkctrl UART3_CLK 0>;
clock-names = "clkctrl";
};
... which is currently not present.
Alternatively you could rename the main_clk in the hwmod_data to point
towards the clkctrl clock, but again, that would be a temporary solution
only.
