Mathieu Malaterre 4c9847b737 dt-bindings: Remove leading 0x from bindings notation
Improve the binding example by removing all the leading 0x to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading "0x"

Converted using the following command:

find Documentation/devicetree/bindings -name "*.txt" -exec sed -i -e 's/([^ ])\@0x([0-9a-f])/$1\@$2/g' {} +

Rob Herring 4da722ca19 dt-bindings: Remove "status" from examples
Pretty much any node can have a status property, so it doesn't need to
be in examples.

Converted with the following command and removed examples with SoC and
board specific splits:

git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d'

Heiko Stübner daecdc6696 pinctrl: rockchip: add support for the rk3368
The rk3368 is the first ARM64 soc from Rockchip, but seems to share most
peripherals with the ARM32 soc, including the pinctrl functionality.
The only notable difference is - as with every Rockchip soc - that the
offsets in the General Register Files moved around and a split of the pmu
section of the rk3288 into pmu and pmugrf (pmu general register files)
sections. The pinctrl driver of course only needs the pmugrf registers
for controlling the pin settings.

Heiko Stübner fc72c923e5 pinctrl: rockchip: generalize bank-quirks
Upcoming Rockchip SoCs have additional quirks to handle. Currently they would
be handled by giving the bank a special compatible property. But the nature
of the new quirks would require a lot of them. Also as we want to move to the
separate dw_gpio driver in the future, these bank-definitions should be
extended at all.

Describing the bank quirks this way also enables us to deprecate the special
bank compatible string for bank0 on rk3188 and simplify the handling code.

Heiko Stübner 6ca5274d1d pinctrl: rockchip: add rk3188 specifics
Besides the pull registers sitting in a separate place, the rk3188 also
has the peculiarity that the pull registers of the first bank are split
and the first half is sitting in the register space of the pmu.

Therefore this adds a special bank-type for the first bank, to handle
the two register sources.

Heiko Stübner d3e5116119 pinctrl: add pinctrl driver for Rockchip SoCs
This driver adds support the Cortex-A9 based SoCs from Rockchip,
so at least the RK2928, RK3066 (a and b) and RK3188.
Earlier Rockchip SoCs seem to use similar mechanics for gpio
handling so should be supportable with relative small changes.
Pull handling on the rk3188 is currently a stub, due to it being
a bit different to the earlier SoCs.

Pinmuxing as well as gpio (and interrupt-) handling tested on
a rk3066a based machine.
