+title: Mediatek Video Decode Accelerator With Multi Hardware
+
+maintainers:
+ - Yunfei Dong <yunfei.dong@mediatek.com>
+
+description: |
+ Mediatek Video Decode is the video decode hardware present in Mediatek
+ SoCs which supports high resolution decoding functionalities. Required
+ parent and child device node.
+
+ About the Decoder Hardware Block Diagram, please check below:
+
+ +---------------------------------+------------------------------------+
+ | | |
+ | input -> lat HW -> lat buffer --|--> lat buffer -> core HW -> output |
+ | || | || |
+ +------------||-------------------+---------------------||-------------+
+ lat workqueue | core workqueue <parent>
+ -------------||-----------------------------------------||------------------
+ || || <child>
+ \/ <----------------HW index-------------->\/
+ +------------------------------------------------------+
+ | enable/disable |
+ | clk power irq iommu |
+ | (lat/lat soc/core0/core1) |
+ +------------------------------------------------------+
+
+ 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.
