The differences include the number of GPIOs and that one is
not required to set the pinmux on request.

The pinmux was generated from linux/arch/arm/mach-davinci/da830.c as of
kernel version 3.7.5. If the driver is used for the da850, then SoC
variant must be specified by CONFIG_SOC_DA850.

Add a generic GPIO driver for the DaVinci DA8xx processors. It is turned
on by defining CONFIG_DA8XX_GPIO and fulfills the generic GPIO interface
specified in <asm/gpio.h> . The driver has support for both manipulating
GPIO pins as well as automatically configuring the pin multiplexor
registers to set the pin function to GPIO.

In preparation for a generic GPIO driver for the DA8xx processors,
rename <asm/arch/gpio_defs.h> to <asm/arch/gpio.h> and fix up all files
which include it.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

Added DA8xx GPIO base addresses in gpio_defs.h and pointers
to different BANKs which can be used to program GPIOs.

Some DaVinci SOC's use GPIOs to enable EMAC and DM9000.
This patch adds some definitions for GPIO registers and also adds
structures for GPIO.
A separate header file is being added so that in future we
can have a DaVinci GPIO driver similer to OMAP.

This is a driver for the S6E63D6 SPI OLED display controller from Samsung.
It only provides access to controller's registers so the client can freely
configure it.
