The ARM core kernel already calls clocksource_of_init() so why
go to all the trouble of locating and probing this node in the
machine. CLOCKSOURCE_OF_DECLARE() will take care of it in the
clocksource driver, and thus we can also get rid of the
dangling header file <linux/clksrc-dbx500-prcmu.h>

These smp_operations structures are not over-written, so add "const"
qualifier and replace __initdata with __initconst.
Also, add "static" where it is possible.

Pull RTC fixes from Alexandre Belloni:
"Two fixes for the ds1307 alarm and wakeup"
* tag 'rtc-4.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux:

Since commit 3fffd1283927 ("i2c: allow specifying
separate wakeup interrupt in device tree") we have
automatic wakeup irq support for i2c devices. That
commit missed the fact that rtc-1307 had its own
wakeup irq handling and ended up introducing a
kernel splat for at least Beagle x15 boards.
Fix that by reverting original commit _and_ passing
correct interrupt names on DTS so i2c-core can
choose correct IRQ as wakeup.
Now that we have automatic wakeirq support, we can
revert the original commit which did it manually.
Fixes the following warning:
[ 10.346582] WARNING: CPU: 1 PID: 263 at linux/drivers/base/power/wakeirq.c:43 dev_pm_attach_wake_irq+0xbc/0xd4()

On the ARM architecture, individual platforms select CONFIG_USE_OF if they
need it, but all device tree code is keyed off CONFIG_OF. When building
a platform without DT support and manually enabling CONFIG_OF, we now
get a number of build errors, e.g.
arch/arm/kernel/devtree.c: In function 'setup_machine_fdt':
arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration]
We could now try to separate the use case of booting from DT vs. the
case of using the dynamic implementation, but that seems more complicated
than it can gain us.
This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM
and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little
extra code when we just want the dynamic OF implementation, but that seems
like a rather obscure case, and this version solves all CONFIG_OF related
randconfig regressions.

Commit b3a72384fe29 ("ARM/PCI: Replace pci_sys_data->align_resource with
global function pointer") introduced an ARM-specific align_resource()
function pointer. This is not portable to other arches and doesn't work
for platforms with two different PCIe host bridge controllers.
Move the function pointer to the pci_host_bridge structure so each host
bridge driver can specify its own align_resource() function.

OMAP CPU hotplug uses cpu1's clocks and power domains for CPU1 wake up
from low power states (or turn on CPU1). This part of code is also
part of system suspend (disable_nonboot_cpus()).
>From other side, cpu1's clocks and power domains are used by CPUIdle. All above
functionality is mutually exclusive and, therefore, lockless clkdm/pwrdm api
can be used in omap4_boot_secondary().
This fixes below back-trace on -RT which is triggered by

Add missing HWMOD_NO_IDLEST hwmod flag for entries not
having omap4 clkctrl values.
The emac0 hwmod flag fixes the davinci_emac driver probe
since the return of pm_resume() call is now checked.
This solves the following boot errors :
[ 0.121429] omap_hwmod: l4_ls: _wait_target_ready failed: -16
[ 0.121441] omap_hwmod: l4_ls: cannot be enabled for reset (3)

This is not needed anymore. Handling a potentially pending imprecise external
abort left behind by the bootloader is now done in a slightly safer way inside
the common ARM startup code.

Some module needs more than one functional clock in order to be accessible,
like the McASPs found in DRA7xx family.
This flag will indicate that the opt_clks need to be handled at the same
time as the main_clk for the given hwmod, ensuring that all needed clocks
are enabled before we try to access the module's address space.

bootargs
Currently kernel crash randomly when K2L EVM is booted without
clk_ignore_unused in the bootargs. This workaround is not needed
on other K2 devices such as K2HK and K2E and with this fix, we can
remove the workaround altogether. netcp driver on K2L uses linked
ram on OSR (On chip Static RAM) and requires the clock to this peripheral
enabled for proper functioning. This is the reason for the kernel crash.
So add the clock node to fix this issue.
While at it, remove the workaround documentation as well.
With the fix applied, clk_summary dump shows the clock to OSR enabled.

GPC irq domain is a child domain of GIC, now all of platform irqs
are inside GPC domain, during the module populate, all devices irq
should have correct type setting in GIC, however, there is no
.irq_set_type callback setting in GPC, so the irq_set_type will be
skipped and cause all irqs' type in /proc/interrupt are "edge" which
mismatch with irq type setting in dtb file. Since GPC has no irq
type setting, so just tell kernel to use irq_chip_set_type_parent.

Though the keyboard driver for GPIO buttons(gpio-keys) will continue to

enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.
This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.
