Tony Lindgren a6cf912c60 ARM: OMAP: Fix i2c cmdline initcall for multiplatform
We only want this initcall to run when the kernel is
booted on omap SoCs. Fix the issue by initializing the
the initcall from separately for omap1 and omap2+.

This fixes the issue for omap2+ multiplatform configs
as we are using omap_subsys_initcall there.

Tony Lindgren 01480bad0a ARM: OMAP: Fix relative includes for shared i2c.h file
As discussed on linux-arm-kernel, we want to avoid
relative includes for the arch/arm/*omap* shared code:

http://www.spinics.net/lists/linux-omap/msg80520.html

To fix this for the shared i2c.h, let's re-introduce
a minimal plat/i2c.h.

Note that drivers must not use this header as it will
break build for omap2+ CONFIG_MULTIPLATFORM builds.

Tony Lindgren c34f7c6962 ARM: OMAP: Make plat-omap/i2c.c port checks local
The common code should not have any omap1 or omap2+
specific code, and should not need to call the cpu_is_omap
macros.

The only remaining user for cpu_is_omap macros is
omap_i2c_nr_ports(). Let's make those checks in
the omap specific implementation of omap_i2c_add_bus()
instead in order to remove cpu_is_omap usage from
the common code.

Tony Lindgren e4c060db2c ARM: OMAP: Split plat/cpu.h into local soc.h for mach-omap1 and mach-omap2
We want to remove plat/cpu.h. To do this, let's first split
it to private soc.h to mach-omap1 and mach-omap2. We have to
keep plat/cpu.h around until the remaining drivers are fixed,
so let's include the local soc.h in plat/cpu.h and for drivers
still including plat/cpu.h.

Once the drivers are fixed not to include plat/cpu.h, we
can remove the file.

This is needed for the ARM common zImage support.

Tony Lindgren 3a8761c027 ARM: OMAP: Split plat-omap/i2c.c into mach-omap1 and mach-omap2
There's no need to keep the device related things in the
common i2c.c as omap2+ is using hwmod. Split the code to
mach-omap1 and mach-omap2 parts and only leave common
code to plat-omap/i2c.c.

Note that as omap1 only has one i2c controller, we can
now remove the old device related macros.

Tony Lindgren 70c494c312 ARM: OMAP1: Make plat/mux.h omap1 only
We are moving omap2+ to use the device tree based pinctrl-single.c
and will be removing the old mux framework. This will remove the
omap1 specific parts from plat-omap.

Jarkko Nikula 9833eff3d7 omap: i2c: Fix muxing for command line enabled bus
The commit b63128e812 broke the pin muxing
for I2C busses that are enabled from the kernel command line.

Fix this by defining the board registration function omap_register_i2c_bus
in common platform code as it was before but keep the muxing in architecture
dependent files.

Tony Lindgren b63128e812 omap: Split i2c platform init for mach-omap1 and mach-omap2
Otherwise we cannot limit new mux code to mach-omap2.
The same signal names should eventually work for other
omaps under mach-omap2.

Note that these pins don't need to be OMAP_PIN_INPUT_PULLUP,
just OMAP_PIN_INPUT is enough.
