Subject: [PATCH v5 6/7] arm64: dts: mediatek: mt8173: Drop VDEC_SYS reg from decoder
Date: Fri, 30 Jun 2023 11:14:12 -0400	[thread overview]
Message-ID: <20230630151436.155586-7-nfraprado@collabora.com> (raw)
In-Reply-To: <20230630151436.155586-1-nfraprado@collabora.com>

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@16000000: duplicate unit-address (also used in node /soc/vcodec@16000000)

The driver makes use of this register space, however, so also add a
phandle to the VDEC_SYS syscon to maintain functionality.
