Why two interrupts of the same number? If there is only one interrupt
line then only one should be specified, no?

This should go into the dtsi file. See the discussion on NAND DT support

We are using common OMAP RTC driver for da850 and other ti SoC's (e.g.am33xx).
I have seen in am33xx.dtsi rtc timer
and alarm interrupts are different. So, two interrupt numbers are expected from
RTC DT node.

[PATCH] ARM: davinci: da850: add interrupt-parent property in soc node
From: Lad, Prabhakar
This patch adds 'interrupt-parent' property in soc node, so that
the child inherits this property, this avoids adding 'interrupt-parent'
to each node.

Okay. Looking at the OMAP-L138 TRM, I see that the IP on that SoC
supports both alarm and timer events and both arrive on the same
interrupt number (as opposed to am335x where they supposedly arrive on
different interrupt lines). What you have looks fine to me considering
this.
Also, the interrupt-parent setting needs to be removed. See the patch
Prabhakar just submitted.
Thanks,
Sekhar

A lot of SOCs including Texas Instruments Davinci family mainly use
video decoders as input devices. Here the initial subdevice node
from where the input really comes is this decoder, for which support
is needed as part of the Media Controller infrastructure. This patch
adds an additional flag to include the decoders along with others,

Such a new entity type needs to be documented in the media DocBook [1].
It probably also deserves a comment here, as DECODER isn't that obvious
like the other already existing entity types. I heard people referring
to a device that encodes analog (composite) video signal into its digital
representation as an ENCODER. :)

[PATCH v6 0/2] ARM: davinci: remoteproc support
This patch series adds remoteproc support for OMAP-L138, along with needed supporting mach-davinci infrastructure. These patches are based on Linus' commit tagged v3.8-rc3 (commit id 9931faca02c604c22335f5a935a501bb2ace6e20) Some notes for reviewers... DOCUMENTATION maintainers: patch 2/2 in this series contains a change to kernel-parameters.txt that adds a description for a new kernel command-line parameter, along with the code that defines the new kernel command-line parameter. You are, of course, free to look at the whole series, but only patch 2/2 is of particular interest. This is actually a subset of the complete patch series, since the other patches in this set have already been committed to a staging area by the tree maintainer.
