6ce041aba3 First batch of AT91 drivers for 3.18:
- reset, poweroff and ram drivers are moved to their proper
   location instead of being in mach-at91 directory. They now use
   the appropriate frameworks.
 - big amount of removal of these machine specific drivers and use
   of the newly created drivers. This lead to an overhaul of the setup.c AT91
   startup code.

64568d1dbd ARM: at91: PIT: (Almost) remove the global variables
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.

f807a89cfe ARM: at91: PIT: Rework probe functions
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.

a7d84d73b9 ARM: at91: PIT: Use of_have_populated_dt instead of CONFIG_OF
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.

Most of the printed messages are using the "AT91:" prefix in the setup.c file,
but not all of them. Moreover, those who add it hardcode it directly in the
message, while the pr_fmt macro makes it easier for us to support such a case.

e657ce689a AT91 reset, poweroff and ram drivers
This tag holds the various new drivers introduced to move code that used to be
 in mach-at91 over to the proper frameworks.
 
 These files are the reboot and poweroff code for all AT91 SoCs but the RM9200,
 and the ram controller driver is not doing much at the time, except for grabing
 the RAM clock in order to leave it always enabled.

Working on Gigabit/PCIe support in U-Boot for Apalis T30 I realised
that the current device tree source includes for our modules only
happen to work due to referencing the on-carrier 5v0 supply from USB
which is not at all available on-module. The modules actually contain
TPS60150 charge pumps to generate the PMIC required 5 volts from the
one and only 3.3 volt module supply. This patch fixes this.

(Note: When back-porting this to v3.16 stable releases, simply drop the
change to tegra30-apalis.dtsi; that file was added in v3.17)

Increase max i2c bus frequency beyond the default for faster
data transfers. According to the manual, these faster speeds are
only available when the board is wired up the right way. In this case,
the vendor kernel has run at this speed for a long time.

sda-delay is needed for talking to RTC on PMIC, otherwise the i2c
controller never sees an ACK. Strangely the other PMIC i2c slave (the
main one) works fine even without this delay. I Chose value 100 to
match the vendor kernel.

Remove specific irq init code in all dt board files: this init procedure
is automatically handled in of_irq_init which is called by the arm irq core
code and is in charge of calling the appropriate aic init functions.
