The call to of_parse_phandle returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage.

2019-01-25media: venus: firmware: check fw size against DT memory region sizeStanimir Varbanov
By historical reasons we defined firmware memory size to be 6MB even that the firmware size for all supported Venus versions is 5MBs. Correct that by compare the required firmware size returned from mdt loader and the one provided by DT reserved memory region. We proceed further if the required firmware size is smaller than provided by DT memory region.

2018-11-23media: venus: firmware: add no TZ boot and shutdown routineVikash Garodia
Video hardware is mainly comprised of vcodec subsystem and video control subsystem. Video control has ARM9 which executes the video firmware instructions whereas vcodec does the video frame processing. This change adds support to load the video firmware and bring ARM9 out of reset for platforms which does not have trustzone. An iommu domain is associated and managed with the firmware device.

2018-02-12soc: qcom: mdt-loader: Return relocation baseBjorn Andersson
In order to implement support for grabbing core dumps in remoteproc it's necessary to know the relocated base of the image, as the offsets from the virtual memory base might not be based on the physical address. Return the adjusted physical base address to the caller. Acked-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2017-07-26media: venus: don't abuse dma_alloc for non-DMA allocationsStanimir Varbanov
In venus_boot(), we pass a pointer to a phys_addr_t into dmam_alloc_coherent, which the compiler warns about: platform/qcom/venus/firmware.c: In function 'venus_boot': platform/qcom/venus/firmware.c:63:49: error: passing argument 3 of 'dmam_alloc_coherent' from incompatible pointer type [-Werror=incompatible-pointer-types] To avoid the error refactor venus_boot function by discard dma_alloc_coherent invocation because we don't want to map the memory for the device. Something more, the usage of DMA mapping API is actually wrong and the current implementation relies on several bugs in DMA mapping code. When these bugs are fixed that will break firmware loading, so fix this now to avoid future troubles. The meaning of venus_boot is to copy the content of the firmware buffer into reserved (and memblock removed) block of memory and pass that physical address to the trusted zone for authentication and mapping through iommu form the secure world. After iommu mapping is done the iova is passed as ane entry point to the remote processor. After this change memory-region property is parsed manually and the physical address is memremap to CPU, call mdt_load to load firmware segments into proper places and unmap reserved memory.

2017-07-26media: venus: fix compile-test build on non-qcom ARM platformArnd Bergmann
If QCOM_MDT_LOADER is enabled, but ARCH_QCOM is not, we run into a build error: ERROR: "qcom_mdt_load" [drivers/media/platform/qcom/venus/venus-core.ko] undefined! ERROR: "qcom_mdt_get_size" [drivers/media/platform/qcom/venus/venus-core.ko] undefined! This changes the 'select' statement again, so we only try to enable those symbols when the drivers will actually get built, and explicitly test for QCOM_MDT_LOADER to be enabled before calling into it.

The buffer parameters describing internal buffers depends on current format, resolution and codec. - functions for calculation of current load of the hardware. Depending on the count of instances and resolutions it selects the best clock rate for the video core. * firmware loader Signed-off-by: Stanimir Varbanov <stanimir.varbanov@linaro.org> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
