60e540d617 sm501: gpio dynamic registration for PCI devices
The SM501 PCI card requires a dyanmic gpio allocation as the number of
cards is not known at compile time.  Fixup the platform data and
registration to deal with this.

that when they are not set, the driver uses the original behvaiour.

dfcffa467b sm501fb: control panel pin usage with platform data flags
This patch makes it possible to control panel pins usage with flags passed
from the platform data.  Without this patch the sm501fb driver always controls
the VBIASEN and FPEN pins.  The polarity and use of these pins are very
platform specific, so this patch introduces the flags
SM501FB_FLAG_PANEL_USE_VBIASEN and SM501FB_FLAG_PANEL_USE_FPEN which enable
the use of these pins.

This patch is needed to support the a Sharp LQ104V1DG21 lcd panel on SuperH
platforms such as R2D-1 and R2D-PLUS boards.  Letting the sm501fb driver
control the FPEN and VBIASEN pins like today just results in lcd panel
flicker.

b6d6454fdb [PATCH] mfd: SM501 core driver
This driver provides the core functionality of the SM501, which is a
multi-function chip including two framebuffers, video acceleration, USB,
and many other peripheral blocks.

The driver exports a number of entries for the peripheral drivers to use.
