This code is so EVM specific, instead of SOC-specific.
In order to connect 2 DM646x chips directly via VPIF
this driver requires quite a bit of tweaking.
(I know because I had to do this before ;) )
I'd appreciate a more loosely coupled subdevice layer.
VPIF itself doesn't use I2C so this stuff sh
Not as far as I know and that's a Good(tm) thing.
Why would you want to do that in the first place?

Taking your advise, here's another try using msmtp. It definately
looked better when sending this stuff to myself.
Thanks for your patience on this one.

a quick
change to U-boot to read out the value
right before it boots into Linux, assuming
Linux doesn't change the DDR2 configuration
which from the looks of the sources, it doesnt.
Thanks,

I'm trying to read out the DDR2 control registers
to obtain information about the DDR2 configuration.
I currently did something like
base = ioremap(0x200, PAGE_SIZE);
result = davinci_readl(0x2008);
iounmap(base);
but this results on kernel Oopses.
I also tried to read base+8 which

You'll need to enable debugging for this module and look at what the problem is
exactly.

This patch should add support for the LEDs and user switches on the DM6467.

It saves you a lot of effort in getting kernel debugging up and running.

Hi Kiruthika,
For high-precision idle'ing refer to the nanosleep() and
clock_nanosleep() functions.
Use CLOCK_MONOTONIC to ensure correct operation around time-leaps
(e.g. as caused by an ntp daemon)
For signals, use the signal interface as already indicated by the other people.
Be aware that you

Hi,
I was browsing through the git at source.mvista.com/git and
couldn't find any drivers for the TSIF/VLYNQ/... interfaces.
Weren't these publicly released by TI?
Google didn't seem to know either.

The bottom line is: I'm glad you can disable the pinmux layer.
(although at first it gave compile-errors on our MV Linux, go figure about QA)

Hi Deepika,
I just hope you haven't been looking at this problem for 2 months,
since I have already answered your question then.
In fact what TI does with the pinmuxing layer in the kernel is very
bad practice, in my opinion.
Setting the pinmux layer and 3V3PWDN registers is not the kernel's

Hi Deepika,
I'm trying to get the DM6467 to boot from UART2 and ran into the same problem.
I suggest you look at the dm646x_serial_reset() function in
arch/arm/mach-davinci/serial.c
and draw your conclusions. You'll need to set the SCR register for
every UART you want to use.
