[PATCH v2 05/10] pinctrl: berlin: use the regmap provided by syscon

[PATCH v2 05/10] pinctrl: berlin: use the regmap provided by syscon

[Antoine Tenart]

The Berlin pin controller nodes are now sub-nodes of the soc-controller
and the system-controller nodes. The register bank is managed by syscon,
which provides a regmap.

Remove the regmap setup from the Berlin pinctrl driver and use the one
provided by syscon.

[PATCH v2 06/10] pinctrl: berlin: use proper compatibles

[Antoine Tenart]

The Berlin pin-controller driver was sharing the chip and system
controller nodes with the clock and the reset drivers. They all shared
the same compatible. With the introduction of the Marvell Berlin MFD
controller, the Berlin pin-controller driver has now its own node.
Update its compatibles to not share anymore the ones of the chip and
system controllers.

[PATCH v2 07/10] Documentation: bindings: move the Berlin pinctrl documentation

[Antoine Tenart]

The Berlin pinctrl documentation was part of the Marvell Berlin SoC
documentation because the Berlin pinctrl configuration was inside the
chip and the system controllers. With the recent rework of the chip and
system controller handling (now an MFD driver registers all sub-devices
of the two soc and system controller nodes and each device has its own
sub-node), the documentation of the Berlin pinctrl driver can be moved
to the generic pinctrl documentation directory.

Linus,

would you mind to give your Acked-by for this and the next patch and
let me take this through Berlin and ARM-SoC tree? The patches only
touch berlin-specific subdirectories in pinctrl/ so there should be
no merge issues expected.

If there are other substantial changes to this driver in this kernel
cycle they will also have to be ACKed and funneled through
Berlin and ARM SoC trees.
