Wha? Given your ordering, is a "google,tentacruel-sku262144" a super-set
of "google,tentacruel-sku262145"? If not, this compatible ordering
doesn't make sense. I can't tell from your description, and the
absence of a
items:
- const: google,tentacruel-sku262145
- const: google,tentacruel-sku262146
- const: google,tentacruel-sku262147
- const: google,tentacruel
- const: mediatek,mt8186
