e07577e1dd Input: lpc32xx-keys - select INPUT_MATRIXKMAP 
This adds a "select" dependency of KEYBOARD_LPC32XX on INPUT_MATRIXKMAP,
as the other drivers are doing in this regard. This fixes the following
compile error if KEYBOARD_LPC32XX is enabled but INPUT_MATRIXKMAP is not:

drivers/input/keyboard/lpc32xx-keys.c:230: undefined reference to
`matrix_keypad_build_keymap'

f799a3d8fe Input: omap-keypad: Remove dependencies to mach includes 
Remove support for omap2+ as it's no longer needed since
it's using matrix-keypad. This way we can remove depency
to plat and mach headers which is needed for ARM common
zImage support.

Also remove INT_KEYBOARD by using omap_kp->irq.

Note that this patch depends on an earlier patch
"ARM: OMAP: Move gpio.h to include/linux/platform_data".

Sorry, " IRQF_DISABLED" got included by mistake.

Subject: [PATCH] Input: omap-keypad: dynamically handle register offsets

Keypad controller register offsets are different for omap4
and omap5. Handle these offsets through static mapping and
assign these mappings during run time.

Tested on omap4430 sdp with 3.4-rc3.
Tested on omap5430evm with 3.1-custom kernel.

The ADP5585 family keypad decoder and IO expander is similar to the ADP5589,
however it features less IO pins, and lacks hardware assisted key-lock

the event codes and bit organization within the port related registers.

Move ADP5589 Register defines from the header file into the main source file.

Introduce some helper functions and disable functions that doesn't

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT 
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

0b28bac5ae Input: fixup X86_MRST selects 
Some of the recent X86_MRST additions make some "select"s
conditional on X86_MRST but missed some related kconfig symbols,
causing:

drivers/built-in.o: In function `ps2_end_command':
(.text+0x257ab2): undefined reference to `i8042_check_port_owner'
drivers/built-in.o: In function `ps2_end_command':

drivers/built-in.o: In function `ps2_begin_command':

drivers/built-in.o: In function `ps2_begin_command':
(.text+0x257b6f): undefined reference to `i8042_lock_chip'

when SERIO_I8042=m, SERIO_LIBPS2=y, KEYBOARD_ATKBD=y.

We need to make i8042 dependant upon !X86_MRST and allow deselecting
atkbd on Moorestown even when !CONFIG_EMBEDDED.
