threeeye bc1d038eac REVVL 6 Pro kernel bring-up: full working tree snapshot (2026-09-12)
Squashed backup commit (no shallow-clone history issues) of
xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream
commit 9eece662e) plus all fixes applied to get everpal_defconfig building
clean against a modern (GCC 15.2.0) toolchain -- see the previous commit
message on the lineage-23.2 branch (also in this repo history is not
available here since this is a squashed snapshot; full incremental history
lives in the local DL380 checkout and the upstream GitHub remote).

* Mediatek JPEG Decoder
Mediatek JPEG Decoder is the JPEG decode hardware present in Mediatek SoCs
Required properties:
- compatible : must be one of the following string:
"mediatek,mt8173-jpgdec"
"mediatek,mt2701-jpgdec"
- reg : physical base address of the jpeg decoder registers and length of
memory mapped region.
- interrupts : interrupt number to the interrupt controller.
- clocks: device clocks, see
Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
- clock-names: must contain "jpgdec-smi" and "jpgdec".
- power-domains: a phandle to the power domain, see
Documentation/devicetree/bindings/power/power_domain.txt for details.
- mediatek,larb: must contain the local arbiters in the current Socs, see
Documentation/devicetree/bindings/memory-controllers/mediatek,smi-larb.txt
for details.
- iommus: should point to the respective IOMMU block with master port as
argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.txt
for details.
Example:
jpegdec: jpegdec@15004000 {
compatible = "mediatek,mt2701-jpgdec";
reg = <0 0x15004000 0 0x1000>;
interrupts = <GIC_SPI 143 IRQ_TYPE_LEVEL_LOW>;
clocks = <&imgsys CLK_IMG_JPGDEC_SMI>,
<&imgsys CLK_IMG_JPGDEC>;
clock-names = "jpgdec-smi",
"jpgdec";
power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>;
mediatek,larb = <&larb2>;
iommus = <&iommu MT2701_M4U_PORT_JPGDEC_WDMA>,
<&iommu MT2701_M4U_PORT_JPGDEC_BSDMA>;
};
