[PATCH 16/32] dt-bindings: Define Kendryte K210 pin functions

[Damien Le Moal <damien.lemoal@xxxxxxx>]

Introduce the dt-bindings file
include/dt-bindings/pinctrl/k210_pinctrl.h to define all possible 255
functions that can be assigned to any of the 48 programmable pins of the
SoC. Macros allowing a device tree to define a pinmux mapping are also
introduced.
