I have a schematic in my master thesis, which shows how the camera sensors are connected to the SoC. The PDF is available here: https://www.uni-oldenburg.de/fileadmin/user_upload/informatik/ag/svs/downlo= ad/thesis/Reichel_Sebastian.pdf The schematic is on page 37 (or 45 if your PDF reader does not use different numbers for the preamble stuff). --Sebastian --wwo6u4ofpcf75nb4 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE72YNB0Y/i3JqeVQT2O7X88g7+poFAliVKIMACgkQ2O7X88g7 +pqQhA/+MvS+RlBq5lSlWktwYMY6QAuIMzNUgR+1iWcPQPuvnTBIV5Aq4RmKGxQ4 PlK1ToFJcF942ZTAKh+LV9JzMi199diZq+m59s07cVXDshKajLU0/UImDbZkDm2+ /t1Bw+r3jKnInzgWzFEusJXUoRZ47TDw8HBY9t1CkplGf5pNl+s0jJ96wR72ddmN K0EGvamtelyzr9iYqQpolCp39TVyr5+ewCF2jipP5dBS8rOiQks4QIRpHQ6TjoaK 2q15y4/WCdRHyY0Jc22d38TzeKSbFLsDbnRDEN/s3ll2kyYyU2X9kAfm/V2WGOaW xs0qWPrpPsisjlJWAQ7k85ocbep7FABt+m/LdBkoy2s/b+LdQ2DvuR/2VHc0brNq MXOgqwPixU4QTHFmlriBtfBcqTXXtJRYJxMNh89AmjNOIstjPvDQubs6IJ3RMbyD iss3CRWOLHusUsHmSWRVXql8OaTB6Wuvw/pLLEfDNYtBs4VFBGWd0Kmp0OChmU28 l+SlALxtXpDmbtW4+ku2pRZHrim904mxgAm3R9YqDrdc1/Fu/Eztp3CbbC6hRGV1 xMNjT3kE4MUakFS5w6Up4cZwzr+Fws4piaf8f7Npm92LTqFyl1O9oV7fnPU3ol5w Rk9bciU3EJP3yltb6ff4V25l63lS4evfVXYvZ3Zcm+xkqYx/75I= =Z4E1 -----END PGP SIGNATURE----- --wwo6u4ofpcf75nb4-- -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
