Hi, Here is the first pass at camera support from the device tree.
Firmware patch: http://dev.laptop.org/~dsd/20120823/fw-camera.patch Kernel patch: http://dev.laptop.org/~dsd/20120823/kernel-camera.patch My next step is to explore putting the camera node as a child of the camera-i2c node, matching the layout of the dcon. That will make the code to find the i2c parent less ugly. Then I plan to investigate having the camera probed directly by i2c-gpio (rather than as a platform device), because i2c-gpio calls of_i2c_register_devices() which creates and probes i2c devices based on child nodes of the i2c-gpio device. This was working on XO-1.75 (system booted, camera worked), but something committed to arm-3.5 in the last couple of days has broken boot (I'll diagnose this next week). For XO-4, I noticed some mmp3-specific code in the firmware related to powering up an island (or something) so there may be a few more steps needed on the kernel side. Also the CCIC driver needs to be turned on in the config. Daniel _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
