^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) Required properties:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) - compatible : "mediatek,mt2701-jpgenc"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) followed by "mediatek,mtk-jpgenc"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) - reg : physical base address of the JPEG encoder registers and length of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) memory mapped region.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) - interrupts : interrupt number to the interrupt controller.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) - clocks: device clocks, see
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) - clock-names: must contain "jpgenc". It is the clock of JPEG encoder.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) - power-domains: a phandle to the power domain, see
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) Documentation/devicetree/bindings/power/power_domain.txt for details.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) - mediatek,larb: must contain the local arbiters in the current SoCs, see
