mfd: New AB8500 driver
Add a new driver to support the AB8500 Power Management chip, replacing the current AB4500. The new driver replaces the old one, instead of an incremental modification, because this is a substantial overhaul including: - Split of the driver into -core and -spi portions, to allow another interface layer to be added - Addition of interrupt support - Switch to MFD core API for handling subdevices - Simplification of the APIs to remove a redundant block parameter - Rename of the APIs and macros from ab4500_* to ab8500_* - Rename of the files from ab4500* to ab8500* - Change of the driver name from ab4500 to ab8500 Acked-by: Linus Walleij <linus.walleij@stericsson.com> Acked-by: Srinidhi Kasagar <srinidhi.kasagar@stericsson.com> Signed-off-by: Rabin Vincent <rabin.vincent@stericsson.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
