+description: |
+  Pinctrl for HiSilicon HiSTB SoCs are commonly separated into two parts. Most
+  pins are controlled via IOCONFIG register space, the rest are controlled
+  within sysctrl core.
+
+  Both support per-pin pinmux and pinconf settings. Though the register fields
+  and offsets may differ.
