The 8th NAND partition should be named "NAND.u-boot-env.backup1"
instead of "NAND.u-boot-env". This is to be consistent with other
TI boards as well as u-boot.

Currently we claim that omap4-panda and omap4-panda-es are essentially
the same, but they are not since PandaBoard-ES uses OMAP4460 and
PandaBoard uses OMAP4430.
So, split the common definition and make the model name available.

Venice2 contains an Atmel MXT touchpad. Add an I2C node for it to DT.
The Linux driver doesn't quite work on this platform yet, but adding
the DT node causes no issues, and will allow the device to work once
the driver is fixed.

Enable CONFIG_ARCH_HIP04 in both hi3xxx_defconfig & multi_v7_defconfig.
Since CONFIG_ARM_LPAE is disabled by default, only 3GB memory could be
support by this defconfig. User should enable CONFIG_ARM_LPAE locally to
support 16GB memory on hip04 platform.
Since hip04 doesn't belong to hi3xxx series, rename hi3xxx_defconfig to
hisi_defconfig.

Multiple CPU clusters are used in Hisilicon HiP04 SoC. Now use MCPM
framework to manage power on HiP04 SoC.
Changelog:
v20:
* Disable L2 prefetch when the whole cluster is down.
* Move disabling snoop filter into power_down() after L2 prefetch
disabled.
* Remove delay in wait_for_power_down() after L2 prefetch disabled.
* Add the sleep polling in wait_for_power_down() again since we
need to wait L2 when the cluster is down.
v19:
* Add comments on those delay hacks.
* Update on checking core enabled counts in wait_for_power_down().
v18:
* Fix to release resource in probe().
* Check whether cpu is already up in the process of making cpu down.
* Add udelay in power up/down sequence.
* Optimize on setting relocation entry.
* Optimize on polling status in wait_for_power_down().
* Add mcpm critical operations.
v17:
* Parse bootwrapper parameters in DTS file.
* Fix to use msleep() in spinlock region.
v16:
* Parse bootwrapper parameters in command line instead.
v13:
* Restore power down operation in MCPM.
* Fix disabling snoop filter issue in MCPM.
v12:
* Use wfi as power down state in MCPM.
* Remove wait_for_powerdown() in MCPM because wfi is used now.

The timer driver is using some global variables to define some variables it has
to use in most of its functions, like the base address.
Use some container_of calls to have a single dynamic (and local) variable to
hold this content.
The only exception is in the !DT case, where the call chain to
at91sam926x_ioremap_pit and then at91sam926x_pit_init as init_time makes it
hard for the moment to pass the physical address of the timer.

The PIT timer driver until now had a single probe function, disregarding wether
it was probed through DT or in the old-style way. This code later on was
calling some DT function to retrieve the proper values for its base address,
interrupts and clocks.
While this was working, it was preventing the usage of CLOCKSOURCE_OF_DECLARE,
and the two different probe path were not as clearly separated as they could
be.
Rework the probe path to take this into account, and switch to
CLOCKSOURCE_OF_DECLARE.

The quite-recently-added analog-tv-connector bindings say that the
compatible string for composite video connector is
"composite-connector". That string is also used in the omap3-n900.dts
file. However, the connector driver uses "composite-video-connector", so
this has never worked.
While changing the driver's compatible string to "composite-connector"
would be safer, as published DT bindings should not be changed, I'd
rather fix the bindings in this case for two reasons:
* composite-connector is a bit too generic name, as it doesn't even hint
at video.
* it's clear that this has never worked, which means no one has used
those bindings, which should make it safe to change this.

instances are added but the non-secure variant is left disabled by default,
as on the majority of boards the bootloader leaves it in secure mode.

Since commit 1dbfa187da ("ARM: irq migration: force migration off CPU
going down") the ARM interrupt migration code on cpu offline calls
irqchip.irq_set_affinity() with the argument force=true. At the point
of this change the argument had no effect because it was not used by
any interrupt chip driver and there was no semantics defined.
This changed with commit 01f8fa4f01 ("genirq: Allow forcing cpu
affinity of interrupts") which made the force argument useful to route
interrupts to not yet online cpus without checking the target cpu
against the cpu online mask. The following commit ffde1de640
("irqchip: gic: Support forced affinity setting") implemented this for
the GIC interrupt controller.
As a consequence the ARM cpu offline irq migration fails if CPU0 is
offlined, because CPU0 is still set in the affinity mask and the
validataion against cpu online mask is skipped to the force argument
being true. The following first_cpu(mask) selection always selects
CPU0 as the target.
Solve the issue by calling irq_set_affinity() with force=false from
the CPU offline irq migration code so the GIC driver validates the
affinity mask against CPU online mask and therefore removes CPU0 from
the possible target candidates.
Tested on TC2 hotpluging CPU0 in and out. Without this patch the system
locks up as the IRQs are not migrated away from CPU0.

ARM: LPAE: drop wrong carry flag correction after adding TTBR1_OFFSET
In commit 7fb00c2fca ("ARM: 8114/1: LPAE:
load upper bits of early TTBR0/TTBR1") part which fixes carrying in adding
TTBR1_OFFSET to TTRR1 was wrong:
addls ttbr1, ttbr1, #TTBR1_OFFSET
adcls tmp, tmp, #0
addls doesn't update flags, adcls adds carry from cmp above:
cmp ttbr1, tmp @ PHYS_OFFSET > PAGE_OFFSET?
Condition 'ls' means carry flag is clear or zero flag is set, thus only one
case is affected: when PHYS_OFFSET == PAGE_OFFSET.
It seems safer to remove this fixup. Bug is here for ages and nobody
complained. Let's fix it separately.

Until now, the machines, even when CONFIG_OF was enabled, were calling
at91sam926x_ioremap_pit to try to map the PIT address using the defined
physical address.
Obviously, with DT, it's not appropriate anymore, and some code was added to
the function to deal with this case.
Unfortunately, this code was conditionned on CONFIG_OF, which can be enabled,
even though no DT was actually used, which would result in such a case, to this
code being executed, without any reason.
Moreover, the logic that was here before to bail out of the function just check
in the DT to see if the PIT node is there, which is the case in all our DTSI.
All this can be made much more straightforward just by using
of_have_populated_dt to bail out.
