This patch cleans a arm-pmu node up for exynos4. Only exynos4412 series
boards have four pmu interrupts. Rest of exynos4 boards, except 4412, have only
two pmu interrupts. Thus, we can define two interrupts in the
exynos4.dtsi and extends the interrupts only exynos4412.dtsi.

d51cad7df8 ARM: dts: remove display power domain for exynos5420
Display domain is removed due to instability issues. Explaining
the problem below:

exynos_init_late triggers the pm_genpd_poweroff_unused which powers
off the unused power domains. This call hits before the trigger to
deferred probes.

DRM DP Panel defers the probe due to supply get failure. By the time,
deferred probe is scheduled again, Display Power Domain is powered
off by pm_genpd_poweroff_unused.

FIMD and DP drivers are accessing registers during Probe and Bind
callbacks. If display domain is enabled/disabled around register
accesses, display domain gets unstable and we are getting Power Domain
Disable fail notification. Increasing the Timeout also didn't help.

routing signals to host USB hub. It also lacks some hw modules not yet

The mask-tpm-reset GPIO is used by the kernel to prevent the TPM from
being reset across sleep/wake.  If we don't set it to anything then
the TPM will be reset.  U-Boot will detect this as invalid
and will reset the system on resume time. This GPIO can always be low
and not hurt anything.  It will get pulled back high again during a
normal warm reset when it will default back to an input.

To properly preserve the TPM state across suspend/resume and to make
the chrome U-Boot happy, properly set the GPIO to mask the
reset to the TPM.

be0b420ad6 ARM: dts: Update the parent for Audss clocks in Exynos5420
Currently CLK_FOUT_EPLL was set as one of the parents of AUDSS mux.
As per the user manual, it should be CLK_MAU_EPLL.

The problem surfaced when the bootloader in Peach-pit board set
the EPLL clock as the parent of AUDSS mux. While booting the kernel,
we used to get a system hang during late boot if CLK_MAU_EPLL was
disabled.

e120fb4596 ARM: dts: dra7-evm: Make VDDA_1V8_PHY supply always on
After clarification from the hardware team it was found that
this 1.8V PHY supply can't be switched OFF when SoC is Active.

Since the PHY IPs don't contain isolation logic built in the design to
allow the power rail to be switched off, there is a very high risk
of IP reliability and additional leakage paths which can result in
additional power consumption.

The only scenario where this rail can be switched off is part of Power on
reset sequencing, but it needs to be kept always-on during operation.

This patch is required for proper functionality of USB, SATA
and PCIe on DRA7-evm.

5acd78c59a Fixes for omaps for issues discovered during the merge window and
enabling of a few features that had to wait for the driver
 dependencies to clear.
 
 The fixes included are:
 
 - Fix am43xx hard reset flags
 
 - Fix SoC detection for DRA722
 
 - Fix CPU OPP table for omap5
 
 - Fix legacy mux parser bug if requested muxname is a prefix of
   multiple mux entries
 
 - Fix qspi interrupt binding that relies on the irq crossbar
   that has not yet been enabled
 
 - Add missing phy_sel for am43x-epos-evm
 
 - Drop unused gic_init_irq() that is no longer needed
 
 And the enabling of features that had driver dependencies are:
 
 - Change dra7 to use Audio Tracking Logic clock instead of a fixed
   clock now that the clock driver for it has been merged
 
 - Enable off idle configuration for selected omaps as all the kernel
   dependencies for device tree based booting are finally merged as
   this is needed to get the automated PM tests working finally with
   device tree based booting
 
 - Add hwmod entry for ocp2scp3 for omap5 to get sata working as
   all the driver dependencies are now in the kernel and this patch
   fell through the cracks during the merge window

The l3 clock derived from core DPLL is actually a divider clock,
with the default divider set to 2. l4 then derived from l3 is a fixed factor
clock, but the fixed divider is 2 and not 1. Which means the l3 clock is
half of core DPLLs h12x2 and l4 is half of l3 (as seen with this patch)

Wildcards in compatible strings should be avoid. "marvell,armada38x"
was recently introduced but was not yet used.

The armada 385 SoC is a superset of the armada 380 SoC (with more CPUs
and more PCIe slots). So this patch replaces the use of
"marvell,armada38x" by the "marvell,armada380" string.
