* mfd: AB8500 debugfsMattias Wallin2010-10-291-0/+5
| | | | | | | | | | | This patch adds the possibility to read and write registers via the debug_fs. It also adds ranges of registers sorted by bank which makes it possible to read all defined registers in a bank.

* mfd: Align ab8500 with the abx500 interfaceMattias Wallin2010-10-291-115/+166
| | | | | | | | | | | | | This patch makes the ab8500 mixed signal chip expose the same interface for register access as the ab3100, ab3550 and ab5500 chip. The ab8500_read() and ab8500_write() is removed and replaced with abx500_get_register_interruptible() and abx500_set_register_interruptible().

* mfd: New AB8500 driverRabin Vincent2010-05-281-0/+444
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>
