[PATCH] davinci: Correct the number of GPIO pins for da850/omap-l138

2009-08-11 Thread Sudhakar Rajashekhara

DA850/OMAP-L138 has 144 pins configurable as GPIO, but
currently this has been configured as 128. This patch
corrects it.

Also, this patch adds the base address for GPIO pins
greater than 128.

[PATCH v2 1/2] ASoC: DaVinci: McASP driver enhacements

2009-08-11 Thread Chaithrika U S

On DA830/OMAP-L137 and DA850/OMAP-L138 SoCs, the McASP peripheral has FIFO
support. This FIFO provides additional data buffering. It also provides
tolerance to variation in host/DMA controller response times.
The read and write FIFO sizes are 256 bytes each. If FIFO is enabled,
the DMA events from McASP are sent to the FIFO which in turn sends DMA requests
to the host CPU according to the thresholds programmed.
More details of the FIFO operation can be found at
http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=
sprufm1fileType=pdf

This patch adds support for FIFO configuration. The platform data has a
version field which differentiates the McASP on different SoCs.

Signed-off-by: Chaithrika U S chaithr...@ti.com

In this version of the patch, the davinci-i2s driver changes have been done
to account acnt member introduced in the dma_params structure. Also, the DAI
format addition has been removed from this patch.

 Pulling into DaVinci git while awaiting merge.
 
Kevin,

This pull has resulted only in updating the drivers/video/Kconfig
file and modifications/additions to other files is missing. Can you
please verify this?

Re: [RFC][PATCH] DM365 RTC Support

Hello.

From: Sandeep Paulraj s-paul...@ti.com



Patch adds support for the RTC Driver in DM365.
Apart from receiving comments on the driver itself
I would also like comments on where i am registering the
RTC Driver for DM365. At present i register the RTC
device in SOC specific file(dm365.c).
RTC INTMUX should most probably be done in some other way
than what i am doing at the moment.
I Added this just before registering the RTC.

Did some basic testing using this driver. hwclock
command works. Also transitions between months/years/leap years
has been verified


   Unfortunately, the very first test in rtc-test doesn't work -- program 
hangs. I'll now point out the bugs in the driver leading to this...

   Wait, the source of the update interrupt is not just free-running 
counter set to 1 second -- it must be synchronized to the RTC time regisers 
update. This timer doesn't have a real update interrupt, so, as David ahve 
already suggested, you shouldn't handle these ioctl's, relying on 
CONFIG_RTC_DEV_UIE_EMUL intead...

[PATCH 1/4 - v2] V4L: vpfe capture driver - adding support for camera capture

2009-08-11 Thread m-karicheri2

From: Muralidharan Karicheri m-kariche...@ti.com

This patch incorporated comments received against v1 patch series.

Following are the major comments incorporated:-
1) retained vpfe_g_std() since for vbi support g_std handling in v4l2 
framework
   is not sufficient.
2) rename name field in vpfe_subdev_info to module_name and camera to 
is_camera.
   also grouped bit field variables

Additional features added on top v1 patch:-
2) vpfe_enable/disable_clock restructered to allow configuration of 
required
   clocks in vpfe_capture configuration. This is required for upcoming 
DM365
   support.

Re: saDisplay + DM6467 showing black an white image in SD Display

2009-08-11 Thread Vinayagam Mariappan

Hi,

I have checked with H264 Stream  with D1 resolution using TI DM6467 Demo
Application. Its working.

But It doest work with our customized MPEG-4 Decoder. I am doubting only my
codec interface

Do you have simple codec interface using VIDEC2 using two output buffer?

Please do help me to fix this issueThis is first time I am doing all
this kind of interface so confusing me.

Regards,
Vinayagam M

  Hi  Vinayagam,

 H264 sample streams are available on TI Extranet:
 https://www-a.ti.com/extranet/cm/product/dvevmsw/dspswext/general/dm355_dvevm.shtml

 Consider TI's decode application,  file
 dvsdk_demos_1_40_00_18/dm6467/decode/video.c is used to set the decoder
 parameters, where Vdec2_Params_DEFAULT and Vdec2_DynamicParams_DEFAULT are
 used to set the default decoder parameters, whose value is mentioned in dmai
 module,  you have to modify height/width of these as per your resolution.
 Same would be the case with
 dvsdk_demos_1_40_00_18/dm6467/decode/display.c where default display
 parameters are set with Display_Attrs_DM6467_VID_DEFAULT.

 Regards,
 Deepika

 Hi,

 I have only H264 TI Codec Lib but I do not find H264 Stream for D1.
 Do you have any sample file?

 Please send me if you have one...

 Its confusing me to Integrate with our customized codec...  As I know, I
 have to do minimal changes to get our customized codec to work with our TI
 Demo Application.
 Could you please me specific things to see?
 Do you have any idea which specific enum directly look into it...?

 Vinayagam M

 Hi,

 Nice to hear that your saDisplay is working now.

 we are not getting video.But I get video data till App. Can you please
 describe in detail, up till which module you are getting correct output.

 I would suggest instead of integrating your decoder, first try to modify
 the application to work at D1 resolution with TI codecs, which are capable
 of decoding D1 resolution also,  for that you would have to change few enums
 in the application. Once that path is clear than integrate your decoder.

 Deepika

 Hi Deepika,
  I just made the saDisplay to work properly.
   Now I have to change the Decoder Application to work with our
 customized decoder which always give video out with D1 resolution...
  The TI Demo Application is for HD Display and I change that to work for
 SD Display. When I integrate our customized decoder with demo application,
 we are not getting video.But I get video data till App.
  Where will be the problem...
