Cover letter [RFC/PATCH 0/7] arm: omap: move more HWMOD data to DT
Quoted 34 lines · Felipe Balbi

Hi,

here's a more complete series showing the out of debugfs interface.

So far only AM43xx has been converted and only those HWMODs which play well with DT and/or are not common with other OMAPs/AM33xx.

I plan to work on AM33xx tomorrow, but this RFC shows what we can achieve WRT HWMOD static data reduction.

As you can see, with AM43xx, data reduction is quite minimal, since it reuses so much from AM33xx, but well, had to start somewhere.

All patches were boot tested with AM437x SK on top of:

commit 1ca7c606de868d172afb4eb65e04e290dbdb51ff

btw, after removing all class and sysconfig static definitions, we get:
