This series adds support for multi hardware decode into mtk-vcodec, by first adding use
of_platform_populate to manage each hardware information: interrupt, clock, register
bases and power. Secondly add core work queue to deal with core hardware message,
at the same time, add msg queue for different hardware share messages. Lastly, the
architecture of different specs are not the same, using specs type to separate them.

This series has been tested with both MT8183 and MT8173. Decoding was working for both chips.

Patches 1~3 rewrite get register bases and power on/off interface.
Patches 4 export decoder pm interfaces.
Patches 5 add to support 8192.
Patch 6 support multi hardware.
Patch 7 separate video encoder and decoder document
Patch 8-17 add interfaces to support core hardware.
Patch 18-19 remove mtk_vcodec_release_dec/enc_pm interfaces.

  Fix platform_set_drvdata.

- Fix comments for patch 4/15
  > Looking up "mediatek,mtk-vcodec-core" to determine if it uses component framwork sounds like...
  Add prameter in pdata, for all platform will use compoent after mt8183

  > + Has asked the same question in [1].  Why it removes the

  Must call component_master_add_with_match after platform_set_drvdata for component architecture.
- Fix yaml files check fail for patch 5/15
- Fix yaml file check fail for patch 14/15

Changes compared with v1:
- Fix many comments for patch 3/14
- Remove unnecessary code for patch 4/14
- Using enum mtk_vdec_hw_count instead of magic numbers for patch 6/14
- Reconstructed get/put lat buffer for lat and core hardware for patch 7/14
- Using yaml format to instead of txt file for patch 12/14

Different platforms may have different numbers of register bases. Gets the
numbers of register bases from dts (sizeof(u32) * 4 bytes for each).

When mtk vcodec decoder is build as a module, we need to export
mtk-vcodec-dec pm functions to make them visible by the other components.

There are more than two hardwares for decoder: LAT0, LAT1 and CORE. In order to
manage these hardwares, register each hardware as independent platform device
for the larbs are different.

Each hardware module controls its own information which includes interrupt/power/
clocks/registers.

Calling of_platform_populate in parent device, and use subdev_bitmap to record
whether the hardwares are registered.

-Mediatek Video Codec
-
-Mediatek Video Codec is the video codec hw present in Mediatek SoCs which
-supports high resolution encoding and decoding functionalities.
-
-Required properties:
-- compatible : must be one of the following string:
-  "mediatek,mt8173-vcodec-enc-vp8" for mt8173 vp8 encoder.
-  "mediatek,mt8173-vcodec-enc" for mt8173 avc encoder.
-  "mediatek,mt8183-vcodec-enc" for MT8183 encoder.
-  "mediatek,mt8173-vcodec-dec" for MT8173 decoder.
-  "mediatek,mt8192-vcodec-enc" for MT8192 encoder.
-  "mediatek,mt8183-vcodec-dec" for MT8183 decoder.
-  "mediatek,mt8195-vcodec-enc" for MT8195 encoder.
-- reg : Physical base address of the video codec registers and length of
-  memory mapped region.
-- interrupts : interrupt number to the cpu.
-- mediatek,larb : must contain the local arbiters in the current Socs.
-- clocks : list of clock specifiers, corresponding to entries in
-  the clock-names property.
-- clock-names: avc encoder must contain "venc_sel", vp8 encoder must
-  contain "venc_lt_sel", decoder must contain "vcodecpll", "univpll_d2",
-  "clk_cci400_sel", "vdec_sel", "vdecpll", "vencpll", "venc_lt_sel",
-  "vdec_bus_clk_src".
-- iommus : should point to the respective IOMMU block with master port as
-  argument, see Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml
-  for details.
-- dma-ranges : describes the dma address range space that the codec hw access.
-One of the two following nodes:
-- mediatek,vpu : the node of the video processor unit, if using VPU.
-- mediatek,scp : the node of the SCP unit, if using SCP.

Separates different architecture for hardware: pure_sin_core
and lat_sin_core. MT8183 is pure single core. Uses .hw_arch to
distinguish.

For lat and core architecture, lat thread will send message to core
thread when lat decode done. Core hardware will use the message
from lat to decode, then free message to lat thread when decode done.

For add new hardware, not only need to lock lat hardware, also
need to lock core hardware in case of different instance start
to decoder at the same time.

Add work queue to process core hardware information.
First, get lat_buf from message queue, then call core
hardware of each codec(H264/VP9/AV1) to decode, finally
puts lat_buf back to the message.

Use the dma_set_mask_and_coherent helper to set vdec
DMA bit mask to support 34bits iova space(16GB) that
the mt8192 iommu HW support.

Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G,
regarding which iova range VDEC actually locate, it
depends on the dma-ranges property of vdec dtsi node.

+
+  As above, there are parent and child devices, child mean each hardware. The child device
+  controls the information of each hardware independent which include clk/power/irq.
+
+  There are two workqueues in parent device: lat workqueue and core workqueue. They are used
+  to lat and core hardware deocder. Lat workqueue need to get input bitstream and lat buffer,
+  then enable lat to decode, writing the result to lat buffer, dislabe hardware when lat decode
+  done. Core workqueue need to get lat buffer and output buffer, then enable core to decode,
+  writing the result to output buffer, disable hardware when core decode done. These two
+  hardwares will decode each frame cyclically.
+
+  For the smi common may not the same for each hardware, can't combine all hardware in one node,
+  or leading to iommu fault when access dram data.

There are only two lines in mtk_vcodec_release_dec_pm, using
pm_runtime_disable and put_device instead directly.

Move pm_runtime_enable outside mtk_vcodec_init_dec_pm to symmetry with
pm_runtime_disable, after that, rename mtk_vcodec_init_dec_pm to *_clk since
it only has clock operations now.

Hello Yunfei,
this series does not apply cleanly on the current linux-next tree.

Can you please rebase?

Thanks,
