Subject: [PATCH v5 6/7] arm64: dts: mediatek: mt8173: Drop VDEC_SYS reg from decoder
Remove the VDEC_SYS register space from the decoder, so that the node
address becomes that of VDEC_MISC, solving the long-standing conflicting
addresses between this node and the vdecsys clock-controller node:
arch/arm64/boot/dts/mediatek/mt8173.dtsi:1365.38-1369.5: Warning (unique_unit_address_if_enabled): /soc/clock-controller@...00000: duplicate unit-address (also used in node /soc/vcodec@...00000)
The driver makes use of this register space, however, so also add a
phandle to the VDEC_SYS syscon to maintain functionality.
