76b40ab41e Merge u-boot/master into u-boot-ti/master
In master we had already taken a patch to fix the davinci GPIO code for
CONFIG_SOC_DM646X and in u-boot-ti we have additional patches to support
DA830 (which is CONFIG_SOC_DA8XX && !CONFIG_SOC_DA850).  Resolve these
conflicts manually and comment the #else/#endif lines for clarity.

Conflicts:
	arch/arm/include/asm/arch-davinci/gpio.h
	drivers/gpio/da8xx_gpio.c

03414ac45e gpio: Build the da8xx_gpio code for the davinci644x device
The differences include the number of GPIOs and that one is
not required to set the pinmux on request.

b9f56698c7 da8xx: Add the missing pinmux for da830 to the gpio driver
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.

365d607033 gpio: Replace ARM gpio.h with the common API in include/asm-generic
ARM boards should use the generic GPIO API
This means changing gpio to unsigned type
Remove the unused gpio_toggle() function which is not part of the API
Comment that free should not modify pin state

f517afd5df DA8xx: add generic GPIO driver
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.
