: ARM: OMAP2+: PRCM move to drivers

Quoted 21 lines · Tero Kristo

Hi,

This set is continuation for the work started earlier to cleanup the CM/PRM and attempt to make it a separate driver. This set depends on these two sets:

CM/PRM cleanup set:
http://marc.info/?l=linux-omap&m=139395000918201&w=2

OMAP2 clock DT set:
http://comments.gmane.org/gmane.linux.ports.arm.omap/111257

This set is pretty huge but the patches can be applied in stages if need be. Anyway, it would be good to get some feedback whether the driver folder locations etc. are good, and whether the effort taken here will be enough to actually move the driver. Clockdomain / powerdomain code can also be moved easily under the drivers/power/omap folder (or someplace else if requested) once this set is in. Also, clockdomain / powerdomain data should be possible to convert to DT format or some sort of firmware blob once this is done.

Quoted 9 lines

Patch #55 in this set is pretty massive as it moves all the C files at the same time, this should probably be split up as multiple patches.

Testing branch pushed here (contains also the CM/PRM cleanup set and OMAP2 clock DT conversion):

tree: https://github.com/t-kristo/linux-pm.git
branch: 3.14-rc4-cm-prm-driver-v1

Tested this branch after rebase to v3.14 final (needed a few manual rebase fixes.. trivial ones)

major fail is around sdp2430 which fails to boot -> with DEBUG_LL sdp2430 : http://slexy.org/raw/s2MRoxsaJH
