Do you mean to describe all the allowed pin items?
for example:
items:
pattern:
'GPIO0/IOX1_DI/SMB6C_SDA/SMB18_SDA|GPIO1/IOX1_LD/SMB6C_SCL/SMB18_SCL'
or
items:
pattern: '^GPIO([0-9]|[0-9][0-9]|[1-2][0-4][0-9]|25[0-6])$'
is good enough?

what do you suggest since the pinctrl doesn't have a reg parameter,
maybe pinctrl: pinctrl@0?
BTW, I have run both dt_binding_check and W=1 dtbs_check, and didn't
see an issue related to the pinctrl: pinctrl@f0800260, do I need to
add another flag to see the issue?
