Subject[PATCH v14 1/3] dt-bindings: spmi: modify the constraint of reg property
Date
The constraint of reg may larger than 1, so we modify to
'minItem: 1' and 'maxItem: 2'.
And adds documentation for the SPMI controller found on
Mediatek SoCs.

Merge [RESEND,v13,2/4] into [RESEND,v13,1/4] for fix yaml
error.
[RESEND,v13,1/4] :
dt-bindings: spmi: modify the constraint of reg property
[RESEND,v13,2/4] :
dt-bindings: spmi: document binding for the Mediatek SPMI
controller
