From a7975473cc41773d9f6d8ea72b48c7656e6cd0f6 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 26 Sep 2014 12:55:30 +0200 Subject: [PATCH] mfd: core: Add helper function to register hotplug devices Hot-pluggable multi-function devices should always be registered with PLATFORM_DEVID_AUTO to avoid name collisions on the platform bus. This helper also hides the memory map and irq parameters, which aren't used by hot-pluggable (e.g. USB-based) devices.
