[PATCH 0/5] Drop more legacy platform data for omap4

[Tony Lindgren]

Hi all,

Here's a series that drops more legacy platform data for omap4
for i2c, watchdogs and d2d modules.

Regards,

Tony

[PATCH 1/5] ARM: dts: Drop custom hwmod property for omap4 i2c

[Tony Lindgren]

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the custom ti,hwmods dts property. We have already
dropped the platform data earlier and have been allocating it
dynamically.

[PATCH 2/5] ARM: OMAP2+: Drop legacy watchdog platform data for omap4

[Tony Lindgren]

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property.

As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.
