Subject: [PATCH 00/14] ti-sysc changes to probe devices with dts data only

Hi all,

Here are some ti-sysc interconnect target module changes that allow
dropping legacy platform data for many devices in favor of devicetree
provided data.

This series depends on patch series "[PATCH 0/7] omap changes to
allocate struct omap_hwmod dynamically".

I'll be posting patches separately to drop platform data. Meanwhile,
the easiest way to test this series is to just temporarily comment
out selected platform data entries one driver at a time. This can be
done in the SoC specific struct omap_hwmod_ocp_if array at the end of
the arch/arm/mach-omap2/omap_hwmod_*_data.c files.

Note that we are not yet handling all the quirks yet listed in
arch/arm/mach-omap2/omap_hwmod.h in "omap_hwmod.flags definitions".
We currently do not yet handle quirks for devices with:

HWMOD_NO_OCP_AUTOIDLE
HWMOD_NO_IDLEST
HWMOD_BLOCK_WFI
HWMOD_FORCE_MSTANDBY
HWMOD_RECONFIG_IO_CHAIN
HWMOD_CLKDM_NOAUTO

I'll be posting patches for these later on as needed.

Regards,

Tony
