Bhupesh is hacking a generic c_can driver and platform bus bindings. The question might be do we need the platform bus bindings or is it better to have AMBA bindings? The platform driver supports 16 and 32 bit attached devices, via IORESOURCE_MEM_{16,32}BIT. Where do we have to look for the AMBA id registers? cheers, Marc --=20 Pengutronix e.K. | Marc Kleine-Budde | Industrial Linux Solutions | Phone: +49-231-2826-924 | Vertretung West/Dortmund | Fax: +49-5121-206917-5555 | Amtsgericht Hildesheim, HRA 2686 | http://www.pengutronix.de | --------------enig4ECECCE2018BA4BDF89C80C2 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk0s3kwACgkQjTAFq1RaXHNNVwCeIgEH/bfVggham+QzE16Zyofh qoUAn3Y8syOESia3Ro29KoRrFPzfpck/ =8Wz6 -----END PGP SIGNATURE----- --------------enig4ECECCE2018BA4BDF89C80C2-- --===============8078486129850451236== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Socketcan-core mailing list Socketcan-core-0fE9KPoRgkgATYTw5x5z8w@public.gmane.org https://lists.berlios.de/mailman/listinfo/socketcan-core --===============8078486129850451236==--
