James Lo Nov. 12, 2021, 5:54 a.m. UTC 
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

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

Combining is not the right thing to do.
