Oh dear. Unfortunately whoever added this support to the MFD core did so in such a manner that it's only supported for device tree systems and only for devices which express the MFD cells as device tree nodes which means that most devices can't it - db8500 has got a reasonably unusual combination there. --PEIAKu/WMn1b1Hv9 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJQMik4AAoJEFJkBDiqVpZ47nIQAIm1B6EY4PuHXk1xOAwfDb1n eJ5ZpW7o9YbAb8579XgpYft1Y490wQDHUPvvXvjnYsFsQGFU8H7xZgPbqgy6WkwC LqvHnHLgDScdjT9OrygFWCGK1IKS8K3zsRAIij74/PsRlrUuGlNqCXuSB1+7t0tz BWPvByecvuS5JIOlI0Sm5/QNsYHVR9laj46A7LRg/qs4OeOVPao9wsmOvVhwBVRo 05wObknMqIv4C+thpiYhsfqLG6/q6J2AxI8TqMKzZDm0RPn+fCmt2WXZGwnStTP5 2EwdxLCH8sgjFpYTEu3JfywEqLTEvrCrgFsGPeXRcrjvQvbV3iybIih38P6SU3/k gdQCTj/d+lYHuXVadW4jOhwmUMkcs+ZDQeqW+tAm3aMvPazgPgdbCFfDxwzKIDEr cyxRNlxxsQaBo+YY2wA89zsfwYScmDhLndSFEdQvSSLcqssz1nvACvb9/Z2G3PI/ CYfMF82NAtWmFujDFqKYCkZIQffOS9ey5jNmaob8N7S/pK61RrBw4cIHwo7y43hF oly9B10NqYLF4wLxLMGMxaG2I+8nhZZNVpQslOvqW+S2UHydEZDkQZiYhgnjkpR2 K4Id6FH+dVn00PlZinV749G+UGTkKS1mUr6RdgBGd9ixnZMl/z1vpm2fjioi8ASF 0PM1Je4DRTph6x6UjAp/ =3lJ1 -----END PGP SIGNATURE----- --PEIAKu/WMn1b1Hv9-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
