+* MediaTek JPEG Encoder
+
+MediaTek JPEG Encoder is the JPEG encode hardware present in MediaTek SoCs
+
+Required properties:
+- compatible : "mediatek,mt2701-jpgenc"
+ followed by "mediatek,mtk-jpgenc"
+- reg : physical base address of the JPEG encoder 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 "jpgenc". It is the clock of JPEG encoder.
+- 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:
+ jpegenc: jpegenc@1500a000 {
+ compatible = "mediatek,mt2701-jpgenc",
+ "mediatek,mtk-jpgenc";
+ reg = <0 0x1500a000 0 0x1000>;
+ interrupts = <GIC_SPI 141 IRQ_TYPE_LEVEL_LOW>;
+ clocks = <&imgsys CLK_IMG_VENC>;
+ clock-names = "jpgenc";
+ power-domains = <&scpsys MT2701_POWER_DOMAIN_ISP>;
+ mediatek,larb = <&larb2>;

The function of mtk_jpeg_adjust_fmt_mplane() equals
mtk_jpeg_g_fmt_vid_mplane(), so use mtk_jpeg_g_fmt_vid_mplane() to
replace it .
Delete the unused ctx parameter.
Using fourcc to distinguish between different formats is more generic,
because that jpeg enc will also use it.

From: Pi-Hsun Shih <[email protected]>
Add two functions that can be used to stop new jobs from being queued /
continue running queued job. This can be used while a driver using m2m
helper is going to suspend / wake up from resume, and can ensure that
there's no job running in suspend process.

pm_runtime_put() after completing it. This can save power for the time

The driver can be instantiated multiple times, e.g. for a decoder and
an encoder. Moreover, other drivers could coexist on the same system.
This makes the static video node number assignment pointless, so switch
to automatic assignment instead.

Right, it shouldn't be there. Looks like a rebase error.
P.S. Please check your remail client settings as all the lines of your
message seem to be just mixed together, as if someone removed the line
breaks.
Hans, is this something you could fix up or we need to revert and
resend?

A seemingly bad rebase introduced a spurious v4l2_m2m_buf_done,
which releases a buffer twice and therefore triggers a
noisy warning on each job:
WARNING: CPU: 0 PID: 0 at drivers/media/common/videobuf2/videobuf2-core.c:986 vb2_buffer_done+0x208/0x2a0
Fix it by removing the spurious v4l2_m2m_buf_done.
