Subject: [PATCH 0/6] Enable decoder for mt8183

This series enables the hardware decoder present on mt8183. At first
glance, the only missing piece is the devicetree node for it, however,
simply adding it as is would cause an address collision between the
first register iospace and the clock-controller node, so a rework of the
dt-binding and driver, as well as addition of a clock, were needed
first.

Tested that H264 decoding works with the hardware decoder on
mt8183-kukui-jacuzzi-juniper-sku16, giving a fluster score of 98/135 on
the JVT-AVC_V1 test suite. And ensured other SoCs (MT8192 and MT8195)
still work as usual.

Nícolas F. R. A. Prado (5):
  media: dt-bindings: mediatek,vcodec: Allow single clock for mt8183
  media: dt-bindings: mediatek,vcodec: Don't require assigned-clocks
  media: dt-bindings: mediatek,vcodec: Remove VDEC_SYS for mt8183
  media: mediatek: vcodec: Read HW active status from clock
  clk: mediatek: mt8183: Add CLK_VDEC_ACTIVE to vdec

Yunfei Dong (1):
  arm64: dts: mediatek: mt8183: Add decoder
