I think the DM644x EVM board changes should be in a separate patch.

In vpif_get_std_info(): std_info doesn't need the NULL test, it was already

In vpif_probe(): local variable q was only assigned. If we error out with

This is a NACK. We shouldn't check for stdid since the function is

Vaibhav,
I have posted a re-worked patch with clocks configuration moved
to ccdc. From your response below, I understand the clocks
are being called differently on different SoCs even though they
use the same IP. So IMO, it is better to customize it on a SoC
by defining the clock names in the

This patch is for adding support for DM365 CCDC. This will allow to

I see -ENXIO -ENOMEM being used by drivers. -ENXIO stands for No such

Vaibhav,
Could you confirm my question below? I need to submit a patch on Monday.
Currently we have vpfe_capture.c file (master/bridge driver) which is
handling clk_get/put, and platform data is providing the details about it.
Ideally we should handle it in respective ccdc driver file, since he

Hi Mauro,
Please pull from http://www.linuxtv.org/hg/~hverkuil/v4l-dvb-timings
I was talking to Sekhar about this and actually he made some good points
about this implementation.
If we consider specific IP, then the required clocks would remain always be
the same. There might be some devices which may not be using some clocks
(so as that specific feature).
Actually we are

Magnus,
Thanks for the patch. For non-page aligned user space pointers I agree
that a fix is needed. Don't you think the while loop in
videobuf_dma_contig_user_get() also needs to be adjusted to include
the last page? I think the while loop checks one page too little in
the non-aligned case

this again.

for linux-davinci tree, please do so at your earliest convenience
so that they are in sync.

Note: Murali made a new function that will fill in the v4l2_dv_enum_preset
based on the preset value. It's not yet in the v4l-dvb repository although
I hope that the timing patches will go in soon. The only thing I'm waiting
for is the revised documentation patch.
I will try to spend some

So, I'm basically trusting that one of you will do the sub-maintainers job
of
adding the patches on a tree and asking me to pull. Currently, Sakari and

also host your -hg trees on any other place and ask me to pull
