MTK H264 Encoder(VENC_SYS) and VP8 Encoder(VENC_LT_SYS) are two independent hardware instance. They have their owner interrupt, register mapping, and special clocks. This patch separates them into two devices. This is a preparing patch for adding device_link between the larbs and venc-device. It's mainly for fixing the problem: https://lkml.org/lkml/2019/9/3/316Acked-by:

Updates binding document since the avc and vp8 hardware encoder in MT8173 are now separated. Separate "mediatek,mt8173-vcodec-enc" to "mediatek,mt8173-vcodec-enc-vp8" and "mediatek,mt8173-vcodec-enc". This patch is not a compatible change, but we must do this modifaction because MediaTek IOMMU add the device_link between the smi-larb device and venc_device, if the venc device call the pm_runtime_get_sync, the smi-larb's pm_runtime_get_sync also be called automatically. There is a bit of backward compatibility for avc encoder, the avc encoder device node still has compatible "mediatek,mt8173-vcodec-enc". Acked-by:

When a request is re-inited it will release all control handler objects that are still in the request. It does that by unbinding and putting all those objects. When the object is unbound the obj->req pointer is set to NULL, and the object's unbind op is called. When the object it put the object's release op is called to free the memory. For a request object that contains a control handler that means that v4l2_ctrl_handler_free() is called in the release op. A control handler used in a request has a pointer to the main control handler that is created by the driver and contains the current state of all controls. If the device is unbound (due to rmmod or a forced unbind), then that main handler is freed, again by calling v4l2_ctrl_handler_free(), and any outstanding request objects that refer to that main handler have to be unbound and put as well. It does that by this test: if (!hdl->req_obj.req && !list_empty(&hdl->requests)) { I.e. the handler has no pointer to a request, so is the main handler, and one or more request objects refer to this main handler. However, this test is wrong since hdl->req_obj.req is actually NULL when re-initing a request (the object unbind will set req to NULL), and the only reason this seemingly worked is that the requests list is typically empty since the request's unbind op will remove the handler from the requests list. But if another thread is at the same time adding a new control to a request, then there is a race condition where one thread is removing a control handler object from the requests list and another thread is adding one. The result is that hdl->requests is no longer empty and the code thinks that a main handler is being freed instead of a control handler that is part of a request. There are two bugs here: first the test for hdl->req_obj.req: this should be hdl->req_obj.ops since only the main control handler will have a NULL pointer there. The second is that adding or deleting request objects from the requests list of the main handler isn't protected by taking the main handler's lock.

This patch adds a 6xx specific boot logic. The goal is to share as much code as possible between 3xx, 4xx and 6xx silicon. We need to do a different write to WRAPPER_INTR_MASK with an additional write to CPU_CS_H2XSOFTINTEN_V6 and CPU_CS_X2RPMh_V6. The other writes are the same for 6xx and non-6xx silicon albeit at different absolute relative locations to the base of the venus address space. Signed-off-by:

An upcoming silicon change places a number of existing blocks within the Venus at different relative offsets to the base address of IO region. In order to handle this difference this patch changes the address offsets of the registers to function as offsets relative to the relevant sub-block of registers within the IO region not the base address of the IO region. As a result of this change venus_readl() and venus_writel() are deleted. Co-developed-by:
