[...] > Phytec informs us that you already asked them for this and have > confirmed that you should have all necessary information now No, it's completely unclear: a) You said above that the 0x3 silicon is pre-production and thus you removed that from the kernel. b) Phytec says you didn't mark the PMICs as preproduction in any way. The question is still, which one is correct? If a), I'm wondering why Phytec didn't get that information. If b), the 0x3 variant must not be removed from the kernel. Could you clarify that? rsc -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 |
