b700f42c86 ARM: dts: dra7xx-clocks: rename pcie clocks to accommodate second PHY instance
There are two instances of PCIe PHY in DRA7xx. So renamed
optfclk_pciephy_32khz, optfclk_pciephy_clk and optfclk_pciephy_div_clk to
optfclk_pciephy1_32khz, optfclk_pciephy1_clk and optfclk_pciephy1_div_clk
respectively. This is needed for adding the clocks for second PCIe PHY
instance.

4310e90847 ARM: dts: dra7xx-clocks: Change the parent of apll_pcie_in_clk_mux to dpll_pcie_ref_m2ldo_ck
Change the parent of apll_pcie_in_clk_mux to dpll_pcie_ref_m2ldo_ck
from dpll_pcie_ref_ck.

Figure 26-22. DPLL_PCIE_REF Functional Block Diagram in vE of DRA7xx ES1.0 TRM
shows the signal name for the output of post divider (M2) is CLKOUTLDO.

Figure 26-21. PCIe PHY Clock Generator Overview shows CLKOUTLDO is used as
input to apll mux.

So the actual output of dpll is dpll_pcie_ref_m2ldo_ck which is also the input
of apll.

147e541369 ARM: dts: dra7xx-clocks: Add divider table to optfclk_pciephy_div clock
Add divider table to optfclk_pciephy_div clock. The 8th bit of
CM_CLKMODE_APLL_PCIE can be programmed to either 0x0 or 0x1
based on if the divider value is 0x2 or 0x1.

Figure 26-21. PCIe PHY Clock Generator Overview in vE of DRA7xx ES1.0 shows the
block diagram of Clock Generator Subsystem of PCIe PHY module. The divider
value if '1' should be programmed in order to get the correct
PCIE_PHY_DIV_GCLK frequency (2.5GHz).

a46631c4cd ARM: dts: dra7: add crossbar device binding
There is a IRQ crossbar device in the soc, which
maps the irq requests from the peripherals to the
mpu interrupt controller's inputs. The Peripheral irq
requests are connected to only one crossbar
input and the output of the crossbar is connected to only one
controller's input line. The crossbar device is used to map
a peripheral input to a free mpu's interrupt controller line.

Here, adding a new crossbar device node and replacing all the peripheral
interrupt numbers with its fixed crossbar input lines.

Add the necessary nodes to enable the LCD controller and the
LCD panel that is attached to the Texas Instruments AM335x
EVMSK platform.  Also setup the necessary pin mux within the
DT file to drive the LCD connector and add the correct
pinmux settings for the lcd pins to be configured to when
the SoC goes into sleep state for the minimum power
consumption.

For the sleep mode LCD pin settings, MUX_MODE7 is chosen as
this corresponds to switching the pins into input GPIO's with
an internal pulldown.  Which has been determined to offer the
lowest power solution vs leaving the pins configured in LCD
mode.

a934fb5bc9 x86/vdso: Fix vdso_install
"make vdso_install" installs unstripped versions of the vdso objects
for the benefit of the debugger.  This was broken by checkin:

6f121e548f x86, vdso: Reimplement vdso.so preparation in build-time C

The filenames are different now, so update the Makefile to cope.

This still installs the 64-bit vdso as vdso64.so.  We believe this
will be okay, as the only known user is a patched gdb which is known
to use build-ids, but if it turns out to be a problem we may have to
add a link.

e0bf7b86da x86/vdso: Hack to keep 64-bit Go programs working
The Go runtime has a buggy vDSO parser that currently segfaults.
This writes an empty SHT_DYNSYM entry that causes Go's runtime to
malfunction by thinking that the vDSO is empty rather than
malfunctioning by running off the end and segfaulting.

This affects x86-64 only as far as we know, so we do not need this for
the i386 and x32 vdsos.

699c659b49 powerpc: Avoid circular dependency with zImage.%
The rule to create the final images uses a zImage.% pattern.
Unfortunately, this also matches the names of the zImage.*.lds linker
scripts, which appear as a dependency of the final images. This somehow
worked when $(srctree) used to be an absolute path, but now the pattern
matches too much. List only the images from $(image-y) as the target of
the rule, to avoid the circular dependency.

7f33e7241d pwm: Changes for v3.16-rc1
The majority of these changes are cleanups and fixes across all drivers.
 Redundant error messages are removed and more PWM controllers set the
 .can_sleep flag to signal that they can't be used in atomic context.
 
 Support is added for the Broadcom Kona family of SoCs and the Intel LPSS
 driver can now probe PCI devices in addition to ACPI devices. Upon shut-
 down, the pwm-backlight driver will now power off the backlight. It also
 uses the new descriptor-based GPIO API for more concise GPIO handling.
 
 A large chunk of these changes also converts platforms to use the lookup
 mechanism rather than relying on the global number space to reference
 PWM devices. This is largely in preparation for more unification and
 cleanups in future patches. Eventually it will allow the legacy PWM API
 to be removed.

2dc24b0d06 ARM: SoC updates for 3.16 (part 2)
This is a small follow-up to the larger ARM SoC updates merged
 last week, almost entirely for the keystone platform.
 
 The main change here is to use the new dma-ranges parsing code
 that came in through Russell's ARM tree. This allows the keystone
 platform to do cache-coherent DMA and to finally support all the
 available physical memory when LPAE is enabled.
 
 Aside from this, the keystone reset driver has been rewritten,
 and there is a small bug fix to allow building the orion5x platform
 again.

   drivers which may speak to SPI NOR flash without providing full SPI support
   (i.e., not part of drivers/spi/)
 - new Freescale QuadSPI driver (utilizing new SPI NOR framework)
 - updates for the STMicro "FSM" SPI NOR driver
 - fix sync/flush behavior on mtd_blkdevs
 - fixup subpage write support on a few NAND drivers
 - correct the MTD OOB test for odd-sized OOB areas
 - add BCH-16 support for OMAP NAND
 - fix warnings and trivial refactoring
 - utilize new ECC DT bindings in pxa3xx NAND driver
 - new LPDDR NVM driver
 - address a few assorted bugs caught by Coverity
 - add new imx6sx support for GPMI NAND
 - use a bounce buffer for NAND when non-DMA-able buffers are used

74845bc2fa powerpc/book3s: Fix guest MC delivery mechanism to avoid soft lockups in guest.
Currently we forward MCEs to guest which have been recovered by guest.
And for unhandled errors we do not deliver the MCE to guest. It looks like
with no support of FWNMI in qemu, guest just panics whenever we deliver the
recovered MCEs to guest. Also, the existig code used to return to host for
unhandled errors which was casuing guest to hang with soft lockups inside
guest and makes it difficult to recover guest instance.

This patch now forwards all fatal MCEs to guest causing guest to crash/panic.
And, for recovered errors we just go back to normal functioning of guest
instead of returning to host. This fixes soft lockup issues in guest.
This patch also fixes an issue where guest MCE events were not logged to
host console.

e6654d5b42 powerpc/book3s: Increment the mce counter during machine_check_early call.
We don't see MCE counter getting increased in /proc/interrupts which gives
false impression of no MCE occurred even when there were MCE events.
The machine check early handling was added for PowerKVM and we missed to
increment the MCE count in the early handler.

We also increment mce counters in the machine_check_exception call, but
in most cases where we handle the error hypervisor never reaches there
unless its fatal and we want to crash. Only during fatal situation we may
see double increment of mce count. We need to fix that. But for
now it always good to have some count increased instead of zero.
