77eaa19e73 dm: pinctrl: Add a way for a GPIO driver to obtain a pin function
GPIO drivers want to be able to show if a pin is enabled for input, output,
or is being used by another function. Some drivers can easily find this
and the code is included in the driver. For some SoCs this is more complex.
Conceptually this should be handled by pinctrl rather than GPIO. Most
pinctrl drivers will have this feature anyway.

Add a method by which a GPIO driver can obtain the pin mux value given a
GPIO reference. This avoids repeating the code in two places.

1f2b4b06ae dm: power: Allow regulators to be omitted from SPL
For some boards the pmic interface is useful but the regulator interface
(which comes with it) is too large. Allow them to be separated such that
SPL can decide which it needs.

d178a1c5b2 spi: Correct device tree usage in spi_flash_decode_fdt()
This function currently searches the entire device tree for a node that
it thinks is relevant. But the node is known and is passed in. Correct the
code and enable it only with driver model, since only driver-model boards
will use it.

This avoids bringing in a large number of strings from fdtdec.

0379597e55 dm: core: Don't set pinctrl for pinctrl devices
There is sort-of race condition when a pinctrl device is probed. The pinctrl
function is called which may end up using the same device as is being
probed. This results in operations being used before the device is actually
probed.

For now, disallow pinctrl operations on pinctrl devices while probing. An
alternative solution would be to move the operation to later in the
device_probe() function (for pinctrl devices only) but this needs more
thought.
