Troy Kisky 5ea6d7c8fc mx6: use CONFIG_MX6 instead of CONFIG_MX6Q 
Use CONFIG_MX6 when the particular processor
variant isn't important.

Reserve the use of CONFIG_MX6Q to
specifically test for quad cores variant.

Benoît Thébaudeau 5dafa4543c mxc: Make gpio_get_value() use PSR 
gpio_get_value() should use PSR like Linux, not DR, because DR does not always
reflect the pin state, while PSR does. This is especially useful to detect a
short circuit on a GPIO pin configured as output, or to read the level of a pin
controlled by a non-GPIO IOMUX function.

Vikram Narayanan d71c9c9fc0 imx: Return gpio_set_value in gpio_direction_output 
Return gpio_set_value in gpio_direction_output.
Earlier it returned 0 and ignored gpio_set_value's return value.

Joe Hershberger 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

Stefano Babic d8e0ca851b IMX: uniform GPIO interface using GPIO framework 
IMX processors has a slightly different interface
to access GPIOs and do not make use of the provided GPIO
framework. The patch substitutes mxc_ specific
functions and make use of the API in asm/gpio.h

Stefano Babic 8627111543 IMX: MX31: Cleanup include files and drop nasty #ifdef in drivers 
As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

Stefano Babic c4ea142424 Use common function to set GPIOs for MX3 and MX5 
The patch adds support for setting gpios to the
MX51 processor and change name to the corresponding
functions for MX31. In this way, it is possible to get rid
of nasty #ifdef switches related to the processor type.
