From: Vladimir Oltean <vladimir.olt...@nxp.com> Looking at the Felix and Ocelot drivers, Maxim asked if it would be possible to use them as a base for a new driver for the Seville switch inside NXP T1040. Turns out, it is! The result is that the mscc_felix driver was extended to probe on Seville.
The biggest challenge seems to be getting register read/write API generic enough to cover such wild bitfield variations between hardware generations. There is a trivial dependency patch on the regmap core which is in Mark Brown's for-next tree: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap.git/commit/?h=for-next&id=8baebfc2aca26e3fa67ab28343671b82be42b22c I didn't know what to do with it, so I just added it here as well, as 01/13, so that net-next builds wouldn't break.
