This uclass is intended for devices that do not need any features from the
uclass, including binding children.
This will typically be used by devices that are used to bind child devices
but do not use dm_scan_fdt_dev() to do it. That is for example the case of
several USB wrappers that have 2 child devices (1 for device and 1 for
host) but bind only one at a any given time.

Previously we have to use serial node only from U-Boot dtb,
because we can't handle two problems to avoid serial intr fail:
- CRU phandle miss match between kernel and U-Boot dtb
- No "clock-frequency" in kernel serial node
These problems are workarund by current code, but the dm serial
seems to be works normally only for uart debug but not other uart.
Since the problems have been solved, let's allow serial driver-device
bind from kernel dtb.

There is not crypto node in kernel dtb for early platform(such as
rk322x/rk3288/rk3368/rk3399, etc), so we decide to add crypto node
always in U-Boot dtb and ignore crypto node from kernel dtb.
This is a way to compatible with early platforms. Actually, we
need crypto during secure boot sequence, the crypto had better
not depends on kernel dtb.

fdtdec_get_addr_size() hard-codes the number of cells used to represent
an address or size in DT. This is incorrect in many cases depending on
the DT binding for a particular node or property (e.g. it is incorrect
for the "reg" property). In most cases, DT parsing code must use the
properties #address-cells and #size-cells to parse addres properties.

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.

For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC),

plumbing and implements the GMAC case for the RK3399.
