| 17:26.54 | marex | ao2: hey, do you have a sec ? |
| 17:27.19 | marex | ao2: I made the camera working (i2c communication is ok now). |
| 17:27.40 | marex | ao2: but I noticed a thing in the soc_camera driver ... how am I supposed to pass i2c platform data through it ? |
| 17:27.57 | marex | the driver overrides them with soc_camera_link ... that probably shouldn't happen |
| 17:44.06 | ao2 | marex, It used to work passing the iclink stuff via the i2c_board_info entry, but now we should use a platform device and I can't get it to work either |
| 17:45.59 | ao2 | see http://patchwork.kernel.org/patch/19830/ |

| 18:14.01 | marex | ao2: argh :/ |
| 18:14.04 | marex | ok, thanks |
| 18:14.19 | marex | ao2: we should probably just fix the soc_camera ? |
| 18:14.30 | ao2 | marex, I think I've found the bug in soc-camera |
| 18:15.08 | marex | line 1173 ? |
| 18:16.36 | ao2 | in soc_camera_probe, the code always get the fail code path and the camera is removed |
| 18:16.44 | ao2 | but I guess this is not the only bug |
| 18:17.02 | ao2 | let me look at line 1173 |
| 18:21.43 | marex | ao2: that's a problem ... because the i2c_client platform data is plain overwritten there |
| 18:21.52 | marex | and we have no other way to push the real i2c data to the sensor |
| 18:22.24 | marex | hm, maybe i2c_get/set_clientdata might work |
| 18:23.43 | ao2 | you need to pass platform data to the sensor driver? |
| 18:26.47 | marex | yes, you need to pass eg. buswidth there |
| 18:26.59 | marex | some other crap probably too |
| 18:33.50 | ao2 | the point is that now you are supposed to pass that using platform_data of the platform_device |
| 18:34.02 | ao2 | or maybe I am missing something |
| 18:34.51 | marex | argh, I gave you wrong line number |
| 18:34.52 | marex | 1181 |
| 18:35.13 | marex | anyway ... the soc_camera plain overwrites the platform_data of the i2c device |
| 18:35.23 | ao2 | icl->board_info->platform_data = icl; |
| 18:35.33 | marex | but the sensor doesn't seem to count on it |
| 18:35.38 | marex | *sensors |
| 18:35.53 | ao2 | I added some debug prints so line numbers are different in my current version |

| 18:36.33 | marex | 1181 icl->board_info->platform_data = icl; |
| 18:36.39 | ao2 | form what I understood you don't eve need to pass the sesor driver in i2c_board_info at all |
| 18:36.43 | ao2 | from |
| 18:36.44 | marex | this overwrites the platform_Data |
| 18:37.48 | marex | ao2: what'll happen there if board_info were NULL ? :-) |
| 18:39.40 | ao2 | that's a good point, but I still don't get the former, are you using the new style with a platform_device? |
| 18:39.50 | ao2 | http://patchwork.kernel.org/patch/19830/ |
| 18:40.09 | ao2 | see you later, sorry, dinner time |
| 18:40.13 | marex | ao2: what was the old style ? ;-) |
| 18:40.23 | marex | hm ... ok ... Im just eating mine here too |

| 19:27.27 | ao2 | marex, here again |
| 19:35.27 | marex | ao2: Im looking into it |
| 19:36.35 | ao2 | with the current code I can see the i2c communication with the sensor, but I don't get a video device. What are your symptoms? |
| 19:36.53 | marex | I dont get the platform data |
| 19:37.13 | marex | I know how to patch the sensor driver and hardcode the sensor data ... then it works |
| 19:38.19 | marex | ao2: see ov772x.c please ... it seems it cant fish the ov772x_priv in the ov772x_video_probe () |
| 19:39.58 | marex | ah it seems it can fish it, but it doesn't get what it's expecting to get |
| 19:47.32 | marex | ao2: maybe we dont need to pass any platform data there |
| 19:47.51 | marex | maybe we can fish all we need from the soc_camera structures |
| 19:48.28 | ao2 | I think that's how it is supposed to work |
| 19:49.12 | marex | ao2: yes, but it also seems all the sensor drivers are borken now |
| 19:49.47 | ao2 | that could well be the case :) |
| 19:50.28 | marex | ao2: we have a problem here :-) |
| 19:51.20 | ao2 | let me see if I can get it to work (again) in my case |
| 19:54.31 | marex | ao2: already getting on fire for a hackaton ? ;-) |
| 19:55.03 | ao2 | I get asleep too easy :) |

| 20:18.26 | ao2 | hi yang |
| 20:22.25 | ao2 | ah marex I've found there are some updates over here: http://download.open-technology.de//soc-camera/20090730/ |
| 20:22.49 | ao2 | maybe it is worth to give them a try |
| 20:29.29 | marex | maybe ... but I'll add support for ov9640 first |
| 20:29.38 | marex | I can unpatch the wrong changes anytime later |
| 21:16.27 | marex | ao2: http://marex.hackndev.com/camera.diff _LOADS_ of hacks, crap etc. |
| 21:16.49 | marex | ao2: feast your eyes as much as you can ;-) |
| 21:17.04 | marex | well ... I can get a photo from it, though the i2c commmunication is cut down to minimum |
| 21:55.49 | ao2 | marex, the board part looks very similar to mine, maybe you can set palmz72_cam_init() in palmz72_pxacamera_platform_data.init |
