Renesas ARM platforms are transitioning from single-platform to
multi-platform kernels using the new ARCH_SHMOBILE_MULTI. Make the
driver available on all ARM platforms to enable it on both ARCH_SHMOBILE
and ARCH_SHMOBILE_MULTI, and increase build testing coverage with
COMPILE_TEST.

There is plenty of consumer hardware (e.g., mac books) that does not use AT
keyboards or PS/2 mice. It therefore makes sense for distro kernels to
build the related drivers as modules to avoid loading them on hardware that
does not need them. As such, these options should no longer be protected by
EXPERT.
Moreover, building these drivers as modules gets rid of the following ugly
error during boot:
[ 2.337745] i8042: PNP: No PS/2 controller found. Probing ports directly.
[ 3.439537] i8042: No controller found

Use the key-matrix layer to interpret key scan information from the EC
and inject input based on the FDT-supplied key map. This driver registers
itself with the ChromeOS EC driver to perform communications.
The matrix-keypad FDT binding is used with a small addition to control
ghosting.

Tegra only supports, and always enables, device tree. Remove all ifdefs
and runtime checks for DT support from the driver. Platform data is
therefore no longer required. Delete the header that defines it, and
rework the driver to parse the device tree directly into struct
tegra_kbc.

These devices are not available on other architectures, so
let's limit them to omap.
If the driver subsystem maintainers want to build test
system wide changes without building for each target,
it's easy to carry a test patch that just strips out the
depends entries from Kconfig files.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl into next/multiplatform
From Linus Walleij:
This patchset will:
- Move all remaining headers out of arch/arm/plat-nomadik/include/plat
out to e.g. include/linux/platform_data
- Delete arch/arm/plat-nomadik
- Convert Nomadik and Ux500 to SPARSE_IRQ
* tag 'kill-plat-sparse-irq' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl:
ARM: plat-nomadik: convert platforms to SPARSE_IRQ
mfd/db8500-prcmu: use the irq_domain_add_simple()
mfd/ab8500-core: use irq_domain_add_simple()
ARM: plat-nomadik: move MTU, kill plat-nomadik
ARM: plat-nomadik: move DMA40 header to <linux/platform_data>
ARM: plat-nomadik: use DIV_ROUND_CLOSEST()
ARM: plat-nomadik: pass IRQ to timer driver
clk/ux500: explicitly include register header
pinctrl/nomadik: merge old pincfg header
pinctrl/nomadik: move the platform data header
ARM: plat-nomadik: move NMK_GPIO_PER_CHIP into gpio-nomadik.h
ARM: plat-nomadik: Introduce new DB8540 GPIO registers
|
|
This moves the MTU timer driver from arch/arm/plat-nomadik
to drivers/clocksource and moves the header file to the
platform_data directory.
As this moves the last file being compiled to an object out
of arch/arm/plat-nomadik, we have to "turn off the light"
and delete the plat-nomadik directory, because it is not
allowed to have an empty Makefile in a plat-* directory.
This is probably also a desired side effect of depopulating
the arch/arm directory of drivers. Luckily we have just
deleted all the <plat/*> include files prior to this so
by moving the last one we may delete the directory.
After this all the Ux500 and Nomadik device drivers live
outside of the arch/arm hierarchy.

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".

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.

This driver adds support for the keypad part of the LM8333 and is
prepared for possible GPIO/PWM drivers. Note that this is not a MFD
because you cannot disable the keypad functionality which, thus,
has to be handled by the core anyhow.

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
functionality. Unfortunately the register addresses are different, as well as
the event codes and bit organization within the port related registers.
Move ADP5589 Register defines from the header file into the main source file.
Add new defines while making sure we don't break existing platform_data.
Add register address translation, and turn device specific defines into variables.
Introduce some helper functions and disable functions that doesn't
exist on the added devices.

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.
