[V2,0/2] Enable hardware jpeg encoder for MT8186

[V2,0/2] Enable hardware jpeg encoder for MT8186

[Irui Wang]

From: kyrie wu <kyrie.wu@mediatek.com>

This series adds support for MT8186 hardware jpeg encoding.

This series has been tested with both MT8186.
Encoding worked for this chip.

Patches 1 Adds jpeg encoder dt-bindings for mt8186

Patches 2 set bit mask for jpegenc to support 34bits iova space,
	which means iova rangement from 0 to 16GB.

Changes compared with v1:
--rebase on latest media_stage tree

[V2,1/2] media: media: jpegenc: add mediatek,mt8186-jpgenc compatible

[Irui Wang]

From: kyrie wu <kyrie.wu@mediatek.com>

Add mediatek,mt8186-jpgenc compatible to binding document.

MT8186 iommu support 0~16GB iova. We separate it to four banks:
0~4G; 4G~8G; 8G~12G; 12G~16G.

The "dma-ranges" could be used to adjust the bank we locate.
If we don't set this property. The default range always is 0~4G.

[V2,2/2] media: media: jpegenc: set bit mask for jpegenc

[Irui Wang]

From: kyrie wu <kyrie.wu@mediatek.com>

set jpeg encode DMA bit mask to support 34bits
iova space(16GB) that the mt8186 iommu HW support.
Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G,
regarding which iova range jpgenc actually locate, it
depends on the dma-ranges property of vdec dtsi node.

Please add Acked-by/Reviewed-by tags when posting new versions. However,
there's no need to repost patches *only* to add the tags. The upstream
maintainer will do that for acks received on the version they apply.

If a tag was not added on purpose, please state why and what changed.
