This series adds support for new SoC MT6873/MT8192/MT8195 to the spmi driver.
This series is based on Chun-Jie's patches[1].
[1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=521655
changes since v14:
- rebase to v5.15-rc1.
- merge two patch(1,2) to one patch(1) to fix yaml error
patch 1. dt-bindings: spmi: modify the constraint of reg property
patch 2. dt-bindings: spmi: document binding for the Mediatek SPMI controller
- correct info of Acked-by in [1/3]

2.18.0
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

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.
