TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.
TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.
This driver is based on TWL4030 and WM8350 MFD drivers.

This allows us to remove cpu_is_omap calls from init_irq functions.
There should not be any need for cpu_is_omap calls as at this point.
During the timer init we only care about SoC generation, and not about
subrevisions.
The main reason for the patch is that we want to initialize only
minimal omap specific code from the init_early call.

Commit db97eb7dfe
(omap: gpmc: enable irq mode in gpmc) enabled interrupts for
GPMC (General Purpose Memory Controller). However, looks like
this patch only works on omap3. Fix the issues to avoid warnings
on omap4 during the boot.
GPMC: number of chip select is 8, CS0 to CS7. One less IRQ
allocated throws below warning at boot:
[ 0.429290] Trying to install type control for IRQ409
[ 0.429290] Trying to set irq flags for IRQ409
Resolve following warning messages in boot when irq chip is not set:
[ 0.429229] Trying to install interrupt handler for IRQ402
[ 0.429229] Trying to install interrupt handler for IRQ403
[ 0.429229] Trying to install interrupt handler for IRQ404
[ 0.429260] Trying to install interrupt handler for IRQ405
[ 0.429260] Trying to install interrupt handler for IRQ406
[ 0.429260] Trying to install interrupt handler for IRQ407
[ 0.429290] Trying to install interrupt handler for IRQ408
Resolve following warning in OMAP4:
[ 0.429290] gpmc: irq-20 could not claim: err -22

Initialize asm_irq_flags in omap_init_irq and use it in
get_irqnr_and_base to detect between omap7xx and omap15xx/16xx.
Note that both INT_1510_IH2_IRQ and INT_1510_IH2_IRQ are defined
as 0, so use INT_1510_IH2_IRQ for both of them.

Several ARM platforms/machines that use FIQ define their value of FIQ_START.
Since FIQ is not implemented for OMAP yet, this definition is missing from
OMAP header files.
Put an arbitrary value for FIQ_START into plat/irqs.h for OMAP. Even if not
used by the FIQ handler for Amstrad Delta, this is required for successfull
compilation of arch/arm/plat-omap/fiq.c that provides several
usefull functions.

OMAP interrupt controller goes to unknown state when there is right
combination of l3,l4 sleep/wake-up transitions, l4 autoidle in
interrupt controller and some interrupt. When this happens, interrupts
are not delivered to ARM anymore and ARM will remain in WFI (wait for
interrupt) until interrupt controller is forced to wake-up
(i.e. lauterbach).
