[PATCH 0/3] OMAP: Add DT bindings to specify when devices should not be idled or reset

We have devices like co-processors, SoC internal busses, memory controllers
etc which should not be idled or reset. In some cases erratas around IP blocks
prevent them from either being idled or reset. Have a way to pass this
information from Device tree, and get rid of similar information that
exists as part of the omap_hwmod data files for various DT only OMAP SoCs.

Patches are tested on am335x beagleboneblack and omap4 panda es boards.

Rajendra Nayak (3):
  ARM: OMAP2+: hwmod: cleanup HWMOD_INIT_NO_RESET usage
  ARM: OMAP2+: Add new bindings for OMAP
  ARM: OMAP2+: Let DT say what devices should not to idled or reset
