2 * cs5535-mfd.c - core MFD driver for CS5535/CS5536 southbridges
3 *
4 * The CS5535 and CS5536 has an ISA bridge on the PCI bus that is
5 * used for accessing GPIOs, MFGPTs, ACPI, etc. Each subdevice has
6 * an IO range that's specified in a single BAR. The BAR order is
7 * hardcoded in the CS553x specifications.
