Subject: [PATCH 1/5] drivers/mfd: Add Freescale MC13783 driver
This driver provides the core Freescale MC13783 support. It
registers the client platform_devices and provides access
to the A/D converter.
Changes since v1:
- use subsys_initcall instead of module_init
- honour origins of the code
- add MC13783 namespace to regulator defines
- use mfd_add_devices to register subdevices
