[PATCH v3 0/4] ARM: DRA7: Add support for DRA72x devices

[Rajendra Nayak]

changes in v3:
Removed wildcards from compatible strings and duplicates from
.dt_compat strings as suggested by Arnd

DRA72x devices are single core Cortex A15 devices belonging to the
DRA7 family (Similar to the DRA74x devices which are dual core Cortex
A15 based)

The patches (based off 3.15-rc2) add minimal DT/kernel modifications to add
boot support for DRA72x devices reusing all the kernel data for DRA74x devices.

[PATCH v3 1/4] ARM: dts: dra7-evm: Remove the wrong and undocumented compatible

[Rajendra Nayak]

"ti,dra752" is neither documented nor correct, since the device is actually a
dra742 device as rightly documented in dt bindings.

DRA72x is a single core cortex A15 device with most infrastructure IPs otherwise

So move the cpu nodes into dra74x.dtsi and dra72x.dtsi respectively.

Also add a minimal dra72-evm dts file.

[PATCH v3 3/4] ARM: OMAP2+: Add machine entry for dra72x devices

[Rajendra Nayak]

The only difference from the dra74x devices is the missing .smp entry.

While at it, also fix the use of __initdata (across the file) and replace them
with __initconst as reported by checkpatch

ERROR: Use of const init definition must use __initconst

Actually, what I meant was that you should list the fill name of the SoC,
e.g. "ti,dra742", not just "ti,dra74". Leaving out the 'x' is not going
to prevent this from breaking when you have a new dra745 that is incompatible.

You can always list more strings, e.g.

	compatible = "ti,dra745", "ti,dra742", "ti,dra74", "ti,dra7";

if you have a dra745 product that is fully compatible with dra742, but the
important part here is that the first string must be the full name.

Since it looks like you are gonna do another respin, care to separate
out the __initdata to __initconst change for existing ones into a
different patch, and limit this patch to just what the patch subject says.

[PATCH v3 3/4] ARM: OMAP2+: Add machine entry for dra72x devices

Since it looks like you are gonna do another respin, care to separate
out the __initdata to __initconst change for existing ones into a
different patch, and limit this patch to just what the patch subject says.

Okay, I will update the device compatibles to something like this..

DRA742
compatible = "ti,dra742", "ti,dra74", "ti,dra7"
DRA722
compatible = "ti,dra722", "ti,dra72", "ti,dra7"

And the evm compatibles as

DRA742 EVM:  Software Developement Board for DRA742
compatible = "ti,dra7-evm", "ti,dra742", "ti,dra74", "ti,dra7"
DRA722 EVM: Software Development Board for DRA722
compatible = "ti,dra72-evm", "ti,dra722", "ti,dra72", "ti,dra7"

I was also calling the .dtsi files as dra72x.dtsi and dra74x.dtsi, do you suggest I call
them dra742.dtsi and dra722.dtsi instead? Just that if we end up with a dra745 which is
fully compatible with dra742, as you mentioned above, we would be using a dra742.dtsi for a dra745
device which could be a little confusing.
