The pinctrl groups for SPI until now were also adding the chip selects in
the SPI pinctrl group.
This was causing a few issues, since a board was forced to use a random
number of chipselects, even though it might use one of these chip selects
for another pin.
The number of chipselects defined was also not the same from one group to
another because of different needs at the time these groups have been
introduced, resulting in no clear view from the board DTS on what exactly
is being muxed, which even might change in the future.
Solve this by creating different pinctrl groups for the chipselects and the
standard SPI pins (CLK, MOSI and MISO) so that we fix both issues.

The Marvell mwifiex driver prevents the system to enter into a suspend

Commit ea08de16eb ("ARM: dts: Add DISP1 power domain for exynos5420")
added a device node for the Exynos5420 DISP1 power domain but dit not
make the DP controller a consumer of that power domain.
This causes an "Unhandled fault: imprecise external abort" error if the
exynos-dp driver tries to access the DP controller registers and the PD
was turned off. This lead to a kernel panic and a complete system hang.
Make the DP controller device node a consumer of the DISP1 power domain

BSYM() was invented to allow us to work around a problem with the
assembler, where local symbols resolved by the assembler for the 'adr'
instruction did not take account of their ISA.
Since we don't want BSYM() used elsewhere, replace BSYM() with a new
macro 'badr', which is like the 'adr' pseudo-op, but with the BSYM()
mechanics integrated into it. This ensures that the BSYM()-ification
is only used in conjunction with 'adr'.

The L3 Error handling on OMAP5 for the most part is very similar
to that of OMAP4, and had leveraged common data structures and
register layout definitions so far. Upon closer inspection, there
are a few minor differences causing an incorrect decoding and
reporting of the master NIU upon an error:
1. The L3_TARG_STDERRLOG_MSTADDR.STDERRLOG_MSTADDR occupies
11 bits on OMAP5 as against 8 bits on OMAP4, with the master
NIU connID encoded in the 6 MSBs of the STDERRLOG_MSTADDR
field.
2. The CLK3 FlagMux component has 1 input source on OMAP4 and 3
input sources on OMAP5. The common DEBUGSS source is at a
different input on each SoC.
Fix the above issues by using a OMAP5-specific compatible property
and using SoC-specific data where there are differences.

With commit bc078316d8 ("ARM: dts: DRA7: Add node for RTC"), we now
have AM57xx RTC register itself as alias 0 even before DS1307 or TPS
rtc drivers are loaded up. However, since neither TPS, nor AM57xx RTC
are capable of being backedup by battery, we would like to maintain
the "primary" rtc as mcp79410 rtc device.
This also generates the following warnings in the bootlog highlighting
the issue:

The interrupt polarity provided in devicetree is used to configure
the interrupt controller(ARM GIC), however, it seems that we have an
inverter at the GIC boundary inside AM57xx which inverts the signal
input from sys_irq external interrupt source.
Further, as per GIC distributor TRM,
http://infocenter.arm.com/help/topic/com.arm.doc.ddi0438d/BGBHIACJ.html#BABJFCFB
ARM GIC distributor does not support IRQ trigger type
IRQ_TYPE_LEVEL_LOW, and only rising or level high signals.
However, for some reason, the current configuration(which gets ignored
by GIC driver) functions on some platforms, however, on few platforms
results in infinite interrupts hogging the system down.
Switch over to rising edge for GIC configuration which is also aligned
with trigger point from the RTC chip and the internal inversion.
