ARM: sun7i: dt: Enable dram gate 5 (tve0 clock) for simplefb TV output

commit 4b8ccef22fb547007ac38c4e5a28a773adee1e6e upstream.

Seems like dram_gate 5 was forgotten when DRAM gating driver was added.

arm/arm64: KVM: Enforce Break-Before-Make on Stage-2 page tables

2016-06-01T19:16:57+00:00

commit d4b9e0790aa764c0b01e18d4e8d33e93ba36d51f upstream.

The ARM architecture mandates that when changing a page table entry
from a valid entry to another valid entry, an invalid entry is first
written, TLB invalidated, and only then the new entry being written.

The current code doesn't respect this, directly writing the new
entry and only then invalidating TLBs. Let's fix it up.

ARM: dts: at91: sam9x5: Fix the memory range assigned to the PMC

2016-05-19T01:35:12+00:00

commit aab0a4c83ceb344d2327194bf354820e50607af6 upstream.

The memory range assigned to the PMC (Power Management Controller) was
not including the PMC_PCR register which are used to control peripheral
clocks.

This was working fine thanks to the page granularity of ioremap(), but
started to fail when we switched to syscon/regmap, because regmap is
making sure that all accesses are falling into the reserved range.

ARM: dts: apq8064: add ahci ports-implemented mask

commit bb4add2ce991e4ec891b5a0287fd1ab77b631979 upstream.

This patch adds new ports-implemented mask, which is required to get
achi working on the mainline. Without this patch value read from
PORTS_IMPL register which is zero would not enable any ports for
software to use.

ARM: SoCFPGA: Fix secondary CPU startup in thumb2 kernel

2016-05-11T09:21:33+00:00

commit 5616f36713ea77f57ae908bf2fef641364403c9f upstream.

The secondary CPU starts up in ARM mode. When the kernel is compiled in
thumb2 mode we have to explicitly compile the secondary startup
trampoline in ARM mode, otherwise the CPU will go to Nirvana.

ARM: EXYNOS: Properly skip unitialized parent clock in power domain on

2016-05-11T09:21:33+00:00

commit a0a966b83873f33778710a4fc59240244b0734a5 upstream.

We want to skip reparenting a clock on turning on power domain, if we
do not have the parent yet. The parent is obtained when turning the
domain off. However due to a typo, the loop is continued on IS_ERR() of
clock being reparented, not on the IS_ERR() of the parent.

Theoretically this could lead to OOPS on first turn on of a power
domain, if there was no turn off before. Practically that should never
happen because all power domains are turned on by default (reset value,
bootloader does not turn off them usually) so the first action will be
always turn off.
