The most obvious thing for this seems to be to add the specific devices to spidev as the OF bindings rather than just register as some non-specific "spidev" so we can change our minds later about how to handle the devices. Not sure that's urgently tasteful but it does mean we move the "we handle this in userspace" bit out of the .dts into the kernel which seems better. --2uzDqHpccQJpqF2n Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJQjF4DAAoJELSic+t+oim9yREP/icNTZWyw52UUCQfkMn9492m DxAwtufJADPdNWxqDufMRlto37Ajajn3TQXJ/pZSyFH/1sy8qnnQRVKDzynUN18T Yb+Gn9/+XPOxfKWKkdEjn7iaWZVhOqirqRvKwWKjAC7ph3Ul9DhN+3N0ODaTluZ6 k7L6HOhtcwFAdez5TJ9zAGnz0k1UMLUUkqLYOYjEigIHA5vrMlF8VkSyHoNtaLXf O/vc9RXEjMniHe39ueKdhne40XR+EBZZoSvGh6Fm0muIMIwfc1RhWKGjkAPpj+hV u7P5FUJ4LQxfvDQ6QErv6R6rzwGfR9b9zVX3d5VU4o58gNqceWRRU1i+NfjExc7a FUFM3ZXASPzTF7EZaLAoVp4I1/dVEVnHO3NiqQUTyHZQajjQ5Q9S692eW2dCxYpN IDR/Ui0SCsNsxTjZ+0wFjbJKHPVpBnFogplNsf9+fCHB6DPkjm2rCuxL1sQHSUN8 ydWwfzM0XHT/ZVO983GRSq0GmvPCJEuKVFhYlYlzCYeSKuoF+CxO1+D7lOtI5UcA nRFW7WRLYCt0VeXP9F67mF4APnflAak0iD25sN0E/DdUORhQ7YCXDWv8iKlQt+Jw +Ln34DRhbGFdWXXpKOiUaTxETDfE7ZU8kFajSxlyN0k2teSb7UIilvvnP0Z451Ly 9hA+93u7mHzmdeu2LIx9 =5xKO -----END PGP SIGNATURE----- --2uzDqHpccQJpqF2n-- --===============3011836264867569386== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============3011836264867569386==--
