ARM: OMAP: timer: obey the !CONFIG_OMAP_32K_TIMER

Currently, omap2_sync32k_clocksource_init() function initializes the 32K
timer as the system clock source regardless of the CONFIG_OMAP_32K_TIMER
setting.
Fix this by providing a default implementation for
!CONFIG_OMAP_32K_TIMER case.

ARM: OMAP: sram: fix OMAP4 errata handling

OMAP4-specific code should be executed only if we are running on

ARM: OMAP: sram: skip the first 16K on OMAP3 HS

In some OMAP3 HS devices (at least Nokia N9 and N950), the public SRAM
seems to conflict with secure portition of SRAM. When booting the 3.6-rc3
kernel (and also earlier) on these devices, the kernel gets tainted with
tons of the following warnings:

	[    6.894348] In-band Error seen by MPU  at address 0
	[...]
	[    6.894378] WARNING: at arch/arm/mach-omap2/omap_l3_smx.c:162

Fix this by skipping the first 16K of the public SRAM. (Note that the
mapping could not be changed, as it resulted in secure monitor call
failure in save_secure_sram().)

This will leave 12K SRAM available that should be still sufficient. The
patch has been boot tested with vanilla 3.6-rc3 on N900, N950 and N9.

ARM: OMAP2+: am33xx: Fix the timer fck clock naming convention

With commit ae6df418a21f3a361c5f9b878e32a8aba4e17692
Sub: ARM: OMAP2+: dmtimer: cleanup fclk usage)
The Timer functional clock naming convention has changed from
gptX_fck => timerXfck, and so as the timer init function
in mach-omap2/timer.c.
OMAP4 clocktree also has changed accordingly.

AM33xx Clock Tree has been merged during rc3-4 timeframe,
before above commit got merged, so similar change is required
for AM33xx as well (Change the gptX_fck => timerX_fck).

Commit 4da71ae6 ("OMAP: clockdomain: Arch specific funcs for

ARM: OMAP4: hwmod data: temporarily comment out data for the sl2if IP block

The OMAP4 sl2if IP block requires some special programming for it to
enter idle. Without this programming, it will prevent the rest of
the chip from entering full chip idle.

This patch comments out the IP block data.

Later, once the appropriate support is available, this patch can be
reverted.

ARM: OMAP4: Fix array size for irq_target_cpu

If NR_IRQS is less than MAX_IRQS, we end up writing past the
irq_target_cpu array in omap_wakeupgen_init():

/* Associate all the IRQs to boot CPU like GIC init does. */
for (i = 0; i < max_irqs; i++)
	irq_target_cpu[i] = boot_cpu;

This can happen if SPARSE_IRQ is enabled as by default NR_IRQS is
set to 16. Without this patch we're overwriting other data during
the boot.

Looks like a similar fix was posted by Benoit Cousson earlier
as "ARM: OMAP2+: wakeupgen: Fix wrong array size for irq_target_cpu"
but was lost.

SSI block has two types of clock:

ipg: bus clock, the clock needed for accessing registers.
per: peripheral clock, the clock needed for generating the bit rate.

Currently SSI driver only supports slave mode and only need to handle
the ipg clock, because the peripheral clock comes from the master codec.

Only register the ipg clock and do not register the peripheral clock for ssi.
