  • [07:19:16] <koen> good morning all
  • [07:19:24] <jkridner> good morning
  • [07:19:31] <jkridner> can't seem to sleep tonight.
  • [07:19:54] <koen> that sucks
  • [07:20:07] <koen> any thoughts on http://groups.google.com/group/beagleboard/browse_thread/thread/63313fb378b06302# ?
  • [07:21:24] <jkridner> trying to remember where I downloaded that patch...
  • [07:21:29] <jkridner> guess I'll just d/l again.
  • [07:24:50] <jkridner> got back to setting up OE for another 1/2 or so today.
  • [07:25:25] <jkridner> what is OE.mtn.bz2 ?
  • [07:26:36] <koen> a compressed monotone database
  • [07:27:01] <jkridner> for a particular distro?
  • [07:27:19] <jkridner> is it common to all of OE?
  • [07:27:29] <jkridner> I didn't know how generic the instructions were on the web.
  • [07:27:44] <jkridner> where did you get lcd_omap3beagle.c?
  • [07:28:25] <koen> I made it by doing s/evm/beagle/ on lcd_omap3evm.c and adjusting the gpio definitions
  • [07:29:20] <jkridner> I don't see either in the .22 kernel. I'm trying to take a quick guess what files would have the same functionality.
  • [07:29:37] <jkridner> where did you pull the timing info?
  • [07:29:49] <jkridner> (and GPIO settings?)
  • [07:30:00] <koen> gpio settings from the hwrm
  • [07:30:05] <koen> timings from .22
  • [07:30:41] <koen> .22 has it in drivers/video/omap/omap_disp_out.c
  • [07:40:21] <jkridner> why do you switch from lcd to panel terminology?
  • [07:41:46] <koen> probably copy/paste errors
  • [07:44:31] <koen> my main objective was to turn on power to the tfp (using gpio 170) in a way that would be like other drivers in omap git
  • [07:44:54] <jkridner|work> k.
  • [07:47:47] <jkridner> well, thanks for putting me to sleep.

  • [15:55:20] <prpplague> koen: not sure what situation you are refering to, but in general hsync and vsync are not considered data lines
  • [15:55:46] <BThompson> agreed, they are more like clocks since they provide synchronization

  • [15:59:18] <koen> I copy pasted this: http://rafb.net/p/x6kYic64.txt

  • [16:02:24] <prpplague> koen: indeed many SoC lcd controllers support different "mapped" or "lookup" tables for lcd configurations
  • [16:02:58] <prpplague> koen: is this the beagle you are working with?
  • [16:03:13] <prpplague> koen: i didn't think the beagle had lcd support

  • [16:25:47] <koen> sakoman: I think it's in kHz, not ps
  • [16:26:48] <sakoman> looking at ref manual -- you will need to change 18 to 24 for beagle since all 24 are wired to the dac
  • [16:27:28] <sakoman> I'm sure you will also need to change the timings
  • [16:28:26] <koen> I changed the timings already :)
  • [16:28:31] <koen> 15200 is 65MHz in ps
  • [16:28:50] <koen> what I meant was that your driver says .pixel_clock is in ps
  • [16:29:08] <koen> and the 2430 driver claims kHz
  • [16:34:51] <sakoman> koen: it probably is -- I did a cut and paste of the pixel clock values from the old style driver & didn't clean up the comments
  • [16:35:07] <sakoman> I'll check to make sure a bit later today
