From 62579266cf9caca5b999560be2b5ceee42fc4d4d Mon Sep 17 00:00:00 2001 From: Rabin Vincent Date: Wed, 19 May 2010 11:39:02 +0200 Subject: 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 Acked-by: Srinidhi Kasagar Signed-off-by: Rabin Vincent Signed-off-by: Samuel Ortiz --- drivers/mfd/Kconfig | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'drivers/mfd/Kconfig') diff --git a/drivers/mfd/Kconfig b/drivers/mfd/Kconfig index b84b7078e909..9da0e504bbe9 100644 --- a/drivers/mfd/Kconfig +++ b/drivers/mfd/Kconfig @@ -420,11 +420,12 @@ config EZX_PCAP This enables the PCAP ASIC present on EZX Phones.
