a617b36bbc Input: ams_delta_serio: use IRQ resource
The driver still obtains IRQ number from a hardcoded GPIO.  Use IRQ
resource instead.

For this to work on Amstrad Delta, add the IRQ resource to
ams-delta-serio platform device structure.  Obtain the IRQ number
assigned to "keybrd_clk" GPIO pin from FIQ initialization routine.

As a benefit, the driver no longer needs to include
<mach/board-ams-delta.h>.

a32d5ce1db ARM: OMAP1: ams-delta FIQ: Keep serio input GPIOs requested
From the very beginning, input GPIO pins of ams-delta serio port have
been used by FIQ handler, not serio driver.

Don't request those pins from the ams-delta-serio driver any longer,
instead keep them requested and initialized by the FIQ initialization
routine which already requests them and releases while identifying GPIO
IRQs.

2bcb1be092 Input: ams_delta_serio: Replace power GPIO with regulator
Modify the driver so it no longer requests and manipulates the
"keybrd_pwr" GPIO pin but a "vcc" regulator supply instead.

For this to work with Amstrad Delta, define a regulator over the
"keybrd_pwr" GPIO pin with the "vcc" supply for ams-delta-serio device
and register it from the board file.  Both assign an absulute GPIO
number to the soon depreciated .gpio member of the regulator config
structure, and also build and register a GPIO lookup table so it is
ready for use by the regulator driver as soon as its upcoming update
is applied.

da564a05b3 ARM: OMAP1: ams-delta: clean up init data section assignments
The main purpose of this patch is to fix several section mismatch
warnings from the board file and a few board specific drivers,
introduced with recent Amstrad Delta patch series, some of them rising
up only when building with CONFIG_MODULES not set.

While being at it, section tagging of all init data found in the board
file have been revised and hopefully corrected and/or optimized.

8d09a1bb31 input: serio: ams-delta: toggle keyboard power over GPIO
Don't use Amstrad Delta custom I/O functions once GPIO interface is
available for the underlying hardware.

While requesting and initializing GPIO pins used, also take care of one
extra pin KEYBRD_DATAOUT which, even if not used by the driver, belongs
to the device and affects its functioning.

Once done, move the driver initialization back to the device_initcall
level, reverting the temporary chane introduced with patch 1/7 "ARM:
OMAP1: ams-delta: register latch dependent devices later".  That change
is no longer required once the driver takes care of registering used
GPIO pins, and it's better to initialize the device before others using
the latch2 based GPIO pins, otherwise a garbage is reported on boot,
perhaps due to random data already captured by the FIQ handler while the
keyboard related latch bits are written with random values during
initialization of those other latch2 dependent devices.

f7519d8c82 ARM: OMAP1: ams-delta: register latch dependent devices later
In preparation to converting Amstrad Delta on-board latches to
basic_mmio_gpio devices, registration of platform devices which depend
on latches and will require initialization of their GPIO pins first,
should be moved out of .machine_init down to late_initcall level, as the
gpio-generic driver is not available until device_initcall time.  The
latch reset operation, which will be replaced with GPIO initialization,
must also be moved to late_initcall for the same reason.

Since there was already another, separate arch_initcall function for
setting up one of those latch dependent devices, the on-board modem
device, reuse that function, i.e., rename it to a name that matches the
new purpose, extend with other device setup relocated from
.machine_init, and move down to the late_initcall level.

While being at it, add missing gpio_free() in case the modem platform
device registration fails.

Thanks to Tony Lindgren <tony@atomide.com> who suggested this approach
instead of shifting up the gpio-generic driver initialization.

In addition, defer registration of the Amstrad Delta ASoC and serio
devices, done from their device driver files, until late_initcall time,
as those drivers will depend on their GPIO pins already requested from
the board late_init() function until updated to register their GPIO pins
themselves.

29453932d8 input: serio: add support for Amstrad Delta serial keyboardport
The patch introduces a serio driver that supports a keyboard serial port found
on the Amstrad Delta videophone board.

After initializing the hardware, the driver reads its input data from a buffer
filled in by the board FIQ (Fast Interrupt Request) handler.

Standard AT keyboard driver (atkbd) will be used on top of the serio layer for
handling the E3 keyboard (called mailboard) connected to the port. Since the
device generated scancodes differ from what the atkbd expects, a custom key
code to scan code table must be loaded from userspace for the keyboard to be
useable.
