The amphion vpu codec ip contains encoder and decoder. Windsor is the encoder, it supports to encode H.264. Malone is the decoder, it features a powerful video processing unit able to decode many formats, such as H.264, HEVC, and other formats. This Driver is for this IP that is based on the v4l2 mem2mem framework. Supported SoCs are: IMX8QXP, IMX8QM Signed-off-by:

Reviewing the RB5 schematic its clear that we have missed out on defining both of the power-rails associated with the CSI PHY. Other PHYs such as the UFS, PCIe and USB connect to these rails and define each regulator individually. This means if we were to switch off the other various PHYs which enable these rails, the CAMSS would not appropriately power-on the CSI PHY. Reviewed-by:

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq_optional(). While at it, propagate error code in case devm_request_irq() fails instead of returning -EINVAL. Signed-off-by:

As the possible failure of the vzalloc(), e->encoder_buf might be NULL. Therefore, it should be better to check it in order to guarantee the success of the initialization. If fails, we need to free not only 'e' but also 'e->name'. Also, if the allocation for ctx fails, we need to free 'e->encoder_buf' else.

The i.MX8M mini appears to have a similar G1 decoder but the post-processing isn't present, so different compatible flag is required. Since all the other parameters are the same with imx8mq, just add the new compatible flag to nxp,imx8mq-vpu.yaml. Signed-off-by:

The VPU in the i.MX8MQ is really the combination of Hantro G1 and Hantro G2. With the updated vpu-blk-ctrl, the power domains system can enable and disable them separately as well as pull them out of reset. This simplifies the code and lets them run independently while still retaining backwards compatibility with older device trees for those using G1. Signed-off-by:
