i took the mask values from CK Hu's Patch, mt7623 uses this table and with it hdmi works again (was broken by the array-commit). I'm not sure on which devices Chun-Kuang has tested it, he only suggests to add the mask again from his commit to fix mt7623.

I can only test on mt7623/BPI-R2...

there is a new patchset for mt8192 which adds a new routing-table, which needs to be extended with mask values (without it wil not work, but maybe duplicate values may work):
