These workarounds do not apply for CONFIG_ARCH_OMAP2PLUS at all,
so let's make it just CONFIG_ARCH_OMAP1.
This is needed to for ARM common zImage changes for
omap2+ to avoid including plat and mach headers.

It really becomes an maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.
Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx6q client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.

'pinctrl_gpio_hog' is used to setup the pin functions, and it is not
neccesarily used only for GPIO pins, so remove 'gpio' from its name

On some machines using a specific hardware for console screen output,
the update of the pixel frame buffer does not work correctly when
using command line edition. This may be due to a memory cache bug
in the machine on which the problem has been found, but an other
solution is possible.
This patch proposes to avoid touching directly the pixel frame buffer
and to rebuild each character using the standard putc() function
on command line edition.
The resulting code is smaller and not obviously slower (no read
access to the pixel frame buffer).
Tested on a Cubox (ARM Marvell Dove 88AP510 SoC).

OMAP Architecture code, passes a few function
pointers for UART driver to use in order to
properly implement Power Management and Wakeup
capabilities.
The problem is that those function pointers,
which are passed (ab)using platform_data on
non-DT kernels, can't be passed down to drivers
through DT.
commit e5b57c0 (serial: omap: define helpers
for pdata function pointers) failed to take DT
kernels into consideration and caused a regression
to DT kernel boot.
Fix that by (re-)adding a check for valid pdata
pointer together with valid pdata->$FUNCTION
pointer.

The Gumstix Overo is a computer on module using an OMAP3 processor.
This module must be plugged into an expansion board.
This patch adds a first device tree support for the Overo, using the
Tobi expansion board. The current support is able to boot and mount
the rootfs from MMC.
This patche also updates the omap3 dtb build target.
Currently working:
- mmc0 (on board microSD)
- i2c0 and i2c2 (i2c1 not used)
- led on GPIO
