[PATCH v2 0/2] ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface lists

[Lokesh Vutla]

This series add seperate ocp interface lists that are specific to dra74x
and dra72x, and moving USB OTG SS4 to dra74x only since its not present
in dra72x. Without this USB OTG SS4 hwmod gives an abort on dra72x.

Adding support for soc_is_dra74x() and soc_is_dra72x() in order to differentiate
between dra74x and dra72x and pass the respective ocp interface lists.

Without this dra72x is crashing on linux-next.
Verified on dra74x evm and dra72x evm using 20140725 linux-next.

[PATCH v2 2/2] ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface lists

[Lokesh Vutla]

From: Rajendra Nayak <rnayak@ti.com>

To deal with IPs which are specific to dra74x and dra72x, maintain seperate
ocp interface lists, while keeping the common list for all common IPs.

Move USB OTG SS4 to dra74x only list since its unavailable in
dra72x and is giving an abort during boot. The dra72x only list
is empty for now and a placeholder for future hwmod additions which
are specific to dra72x.

Queued with a fix for the comment style - i.e.,

+       if (ois[0] == NULL) /* Empty list */

rather than 

+       if (ois[0] == NULL) /* Empty list*/

Please keep an eye out for this.

Paul, Tony,

we are at 3.17-rc2 today, unfortunately..
http://slexy.org/view/s20MbRgipa dra72-evm is still broken due to
this. Needs:
https://patchwork.kernel.org/patch/4632161/ and
https://patchwork.kernel.org/patch/4632171/

What can we do to help speed this along?

A simple reminder, like this one, is good.  Also providing boards and 
documentation generally helps, so the patches can be tested and reviewed.

TI is working diligently towards a public TRM and potentially a
related platform as well for all.

Unfortunately, I am not yet aware of a official finalized release
date.. hopefully this year..

In the meanwhile, we will try to provide test logs that you may desire
for at least the
platforms we have functioning and access to. please feel free to
request specific test
vectors if you feel our coverage is not good enough.

Thanks.  You've been showing a lot of great leadership in proactively 
posting test logs.  What I'd suggest doing is to keep that up, and if 
possible, post one of the test reports for each patch series that's 
posted, if possible.

I do have automated scripts verifying various defconfigs on a daily
basis for linux-next and master tags..
https://github.com/nmenon/kernel-test-logs/ (based on each tag).

Every TI engineer does have access to these platforms as well as I do.
Realistically, few platforms do go offline and online as time goes on.
we will try to post test reports for each series as much as our TI
policies let us.
