Most of these are from source'ing a file within an 'if PINMUX', and then
adding another 'depends on PINMUX' within it.
'if FOO' is just shorthand for adding 'depends on FOO' to each item
within the 'if'. There are no "conditional includes" in Kconfig, so
'if FOO' has no special meaning around a 'source'. Conditional includes
wouldn't be possible, because an 'if' condition could include (directly
or indirectly) forward references to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

This option controls the priority of pinmux device initialization.
|
|
Higher priority ensures that the device is initialized earlier in
|
|
the startup cycle. Note that the pinmux device needs to be initialized
|
|
after clock control device, but possibly before all other devices.
|
|
If unsure, leave at default value 2
