The osiris-dvs driver calls functions exported by the tps65010
driver, so we have to ensure that driver is enabled first.
Using 'select' here doesn't work all that well, because it
requires I2C to be enabled in turn.

The gta02 has always been broken in the case when CONFIG_PCF50633_ADC
is not used, since gta02_charger_worker then passes a nonexisting
variable into the pcf50633_mbc_usb_curlim_set() function.
This addresses the obvious typo by using the variable that is
used everywhere else in this file.

Building the integrator platform without TTY support currently
results in a build failure because we always turn on the
pl010 or pl011 drivers. Changing this to a conditional 'select'
statement enables us to build more random configurations, although
it should have little impact for practical configurations.

Commit b713aa0b15 "ARM: fix asm/memory.h build error" broke some
configurations on mach-realview with sparsemem enabled, which
is missing a definition of PHYS_OFFSET:
arch/arm/include/asm/memory.h:268:42: error: 'PHYS_OFFSET' undeclared (first use in this function)
#define PHYS_PFN_OFFSET ((unsigned long)(PHYS_OFFSET >> PAGE_SHIFT))
arch/arm/include/asm/dma-mapping.h:104:9: note: in expansion of macro 'PHYS_PFN_OFFSET'
return PHYS_PFN_OFFSET + dma_to_pfn(dev, *dev->dma_mask);
An easy workaround is for realview to define PHYS_OFFSET itself,
in the same way we define it for platforms that don't have a private
__virt_to_phys function.

The global screen_info structure is used to communicate
data about the console from platform code to the console
driver, but is only defined on ARM if either the VGA or
dummy consoles are in use.
This changes the footbridge code so we don't try to access
this structure in case it is not defined, which prevents
a possible randconfig build error.

The dc21285.c source file cannot be built when CONFIG_PCI is

The trizeps4 and trizeps4wl platforms are both implemented
using the same board file. Since the trizeps4wl code is a
superset of trizeps4, it makes no sense to enable just the
latter, but with the current Kconfig logic, it causes the
board file not to be built at all.
Selecting MACH_TRIZEPS4 from MACH_TRIZEPS4WL ensures that
we are actually building the board file.

The Arcom/Eurotech VIPER SBC enables the I2C_GPIO driver, but
that has a dependency on I2C, and causes build failures if I2C
is disabled. To keep existing configurations running while fixing

I2C_GPIO if I2C is already enabled.

The functions declared in include/linux/pxa2xx_ssp.h are
defined in plat-pxa/ssp.c, which can also be built for
PLAT_MMP, but may be disabled there. This can lead to
both unresolved symbols at link time and to duplicate

Changing the #ifdef in the header file to match the
Kconfig symbol that decides if the file is built solves

We normally don't hard-enable Kconfig options just because
a board contains a specific piece of hardware. In this case,
selecting SMC91X causes a build error, if we don't also enable
basic network device driver support.
Since the platform has no direct dependency on this driver
at link time, we can just remove the 'select' statement.

The code for h2 and osk implicitly assumes that the tps65010
driver is built-in, in order to perform the initial regulator
setup.
This is fine for most real uses, but it does get into the way
of build testing with 'make randconfig', since we don't want
platforms to implicitly select device drivers and subsystems
such as I2C.
This patch by contrast changes the board files to not call
into the tps65010 driver when that is not built-in, allowing
us to build all configurations including some that will not
work properly on this hardware.

However, this fails to build on no-MMU kernels because the

we can simply get away by enclosing the broken function call

The DAVINCI_DA850_EVM board uses an unusual method to
enable the GPIO_PCA953X and KEYBOARD_GPIO_POLLED symbols,
which leads to the dependencies on these symbols being

can lead to build failures when I2C is disabled.
This patch removes the duplicate symbol definitions

Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.
To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.
Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

Pull twi tracing fixes from Steven Rostedt:
"Two urgent fixes in the tracing utility.
The first is a fix for the way the ring buffer stores timestamps.
After a restructure of the code was done, the ring buffer timestamp
logic missed the fact that the first event on a sub buffer is to have
a zero delta, as the full timestamp is stored on the sub buffer
itself. But because the delta was not cleared to zero, the timestamp
for that event will be calculated as the real timestamp + the delta
from the last timestamp. This can skew the timestamps of the events
and have them say they happened when they didn't really happen.
That's bad.
The second fix is for modifying the function graph caller site. When
the stop machine was removed from updating the function tracing code,
it missed updating the function graph call site location. It is still
modified as if it is being done via stop machine. But it's not. This
can lead to a GPF and kernel crash if the function graph call site
happens to lie between cache lines and one CPU is executing it while
another CPU is doing the update. It would be a very hard condition to
hit, but the result is severe enough to have it fixed ASAP"
