Currently our serial device search chokes on the fact that the serial

This patch changes the fallback logic so that even when a serial device
was not probed correctly, we just try the next ones until we find one that
works.

The BCM2835 family of SoCs has 2 different SD controllers: One based on

The bcm283x family of SoCs have a GPIO controller that also acts as
pinctrl controller.
This patch introduces a new pinctrl driver that can actually properly mux
devices into their device tree defined pin states and is now the primary
owner of the gpio device. The previous GPIO driver gets moved into a
subdevice of the pinctrl driver, bound to the same OF node.
That way whenever a device asks for pinctrl support, it gets it
automatically from the pinctrl driver and GPIO support is still available
in the normal command line phase.

Linux uses the properties 'assigned-clocks', 'assigned-clock-parents'
and 'assigned-clock-rates' to configure the clock subsystem for use
with various peripheral nodes.
This implements clk_set_defaults() and hooks it up with the general
device probibin in drivers/core/device.c: when a new device is probed,
clk_set_defaults() will be called for it and will process the
properties mentioned above.
Note that this functionality is designed to fail gracefully (i.e. if a
clock-driver does not implement set_parent(), we simply accept this
and ignore the error) as not to break existing board-support.

clk: support assigned-clock, assigned-clock-parents, assigned-clock-rates
For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC),
the parent-clock needs to be set via the DTS. This adds the required
plumbing and implements the GMAC case for the RK3399.
END
This implements the (newly added) set_parent() operation for the
RK3399 with a focus on allowing the RGMII clock parent to be
configured via the assigned-clock-parents property of the GMAC node.
This implementation supports only the GMAC (in fact only the RGMII
clock parent) and allows to set this clock's parent either to the
internal SCLK_GMAC or to an external clock input (identifiable by it
providing a 'clock-output-name' of "gmac_clkin").

The logic in clk_get_by_index() may be useful for other properties
than 'clocks': e.g. 'assigned-clocks' and 'assigned-clock-parents'

This commit refactors clk_get_by_index() by introducing an internal
function clk_get_by_indexed_prop() that allows to specify the name
of the property to process. The original clk_get_by_index() call
is simply directed through this helper function with the property
name fixed to "clocks".
