[PATCH v3 3/5] arm64: dts: ti: iot2050: Definitions for runtime pinmuxing

Fri Nov 3 11:32:19 PDT 2023


From: Benedikt Niedermayr <benedikt.niedermayr at siemens.com>

Add multiple device tree nodes in order to support
runtime pinmuxing via debugfs.

All nodes are added to the pinctrl device node,
since they are now belonging to multiple interfaces now.

Note: Pinconf is also handled by debugfs-pinmux. This is possible since
pinconf and pinmux accessing the same 32-Bit register and setting the
function mask to 32-Bit allows writes to the whole register.
