Peter Rosin 5e04822f7d ARM: dts: at91: fixes uart pinctrl, set pullup on rx, clear pullup on tx
Remove pullup on uart TX signals, they are push-pull outputs thus
pullups are pointless.

Add pullup on uart RX signals, they prevent the RX signals to be left
floating and so consuming a useless extra amount of power in crowbarred
state if nothing is connected to RX.

Alexandre Belloni f25f2b11cb ARM: dts: at91: at91sam9x5: TC blocks are also simple-mfd and syscon devices
Add simple-mfd and syscon to the TC blocks to allow to register one of the
channels as clocksource properly at boot time and free up the remaining

Note that we keep using old bindings in at91rm9200.dtsi because this

Boris Brezillon aab0a4c83c ARM: dts: at91: sam9x5: Fix the memory range assigned to the PMC
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.

Alexandre Belloni 12dde44998 ARM: at91/dt: sam9x5 crystals under the clocks node
Having clocks grouped in a subnode is common practice, so move the crystals and
the ADC clock under a clocks node for the at91sam9x5 SoC and at91sam9x5 based
boards.

Boris BREZILLON d195608acc ARM: at91/dt: split sam9x5 peripheral definitions
This patch splits the sam9x5 peripheral definitions into:
- a common base for all sam9x5 SoCs (at91sam9x5.dtsi)
- several optional peripheral definitions which will be included by specific
  sam9x5 SoCs (at91sam9x5_'periph name'.dtsi)

This provides a better representation of the real hardware (drop unneeded
dt nodes) and avoids future peripheral id conflict (lcdc and isi both use
peripheral id 25).
