The following V3 of the series is based on v3.15-rc1 + peter's patch series:
patch #1: https://patchwork.kernel.org/patch/3923141/
(drivers: bus: omap_l3: Convert to use devm_kzalloc)

patch #2: https://patchwork.kernel.org/patch/3923061/
(drivers: bus: omap_l3: Convert to use devm_ioremap_resource() )

patch #3: https://patchwork.kernel.org/patch/3923101/
(drivers: bus: omap_l3: Convert to use devm_request_irq())

patch #4: https://patchwork.kernel.org/patch/3923081/
(drivers: bus: omap_l3: Remove the platform driver's remove function)

patch #5: https://patchwork.kernel.org/patch/3923121/
(drivers: bus: omap_l3: Change pr_crit() to dev_err() when IRQ request
fails)

V1 was originally posted here: http://marc.info/?l=linux-omap&m=139749383932575&w=2
V2 was originally posted here: http://marc.info/?l=linux-kernel&m=139776814925544&w=2

V3: has the following changes (w.r.t v2):
- fixed relaxed commit message and usage.
- AM437x internal documents showed that:
- new master information updated into the data
- masterid register definition is different from OMAP4-DRA7 - some
additional parsing is done in hardware to "avoid s/w parsing"
- Additional testing information showed logic fail for masking "unclearable"
new patch added to series - patch #15
- Picked up previous acks and tested by - minor changes verified

This series cleansup omap_l3_noc driver and adds data to support DRA7
and AM437x SoCs.

Patches(including Peter's) is available here:(based on v3.15-rc1):

(posted here: http://marc.info/?l=linux-omap&m=139750288003978&w=2)
- no change in dts.
