Every time dvb_frontend_ops.set_frontend() is called, an almost full reinit of the demodulator will be performed. While this might cause a slight delay when switching channels due to all involved tables being rewritten, it can even be dangerous in certain causes in that the demod may lock up and requires to be powercycled (this can happen on Digital Devices hardware). So this adds a flag if it should be done, and to not change behaviour with existing card support, it'll be enabled in all cases. Signed-off-by:

This moves the PLL SETUP code from stv0367ter_init() into a dedicated function, and also make it possible to configure 58Mhz IC speed at 27MHz Xtal (used on STV0367-based DDB cards/modules in QAM mode). Signed-off-by:

Move the *ter and *cab st_register tables into a separate header file and additionally organize them via a multidimensional array, allowing to add more tables with differing init values, and also prepare for a base init table which should contain general setup values. Also add a state var to store the table triplet to be used. Also fixes three minor style problems reported by checkpatch. Signed-off-by:

Change defaults table writing so tables can be of dynamic length without having to keep track of their lengths by adding and evaluating an end marker (reg 0x0000), also move table writing to a dedicated function to remove code duplication. Additionally mark st_register tables const since they're used read-only. Signed-off-by:

The CPAMP log lines generated in stv0367_ter_check_cpamp() are printed everytime tuning succeeds or fails, quite cluttering the normal kernel log. Use dprintk() instead of printk(KERN_ERR...) so that if the information is needed, it'll be printed when the stv_debug modparam is enabled. Signed-off-by:

Some hardware and bridges (namely ddbridge) require that tuner access is limited to one concurrent access and wrap i2c gate control with a mutex_lock when attaching frontends. According to vendor information, this is required as concurrent tuner reconfiguration can interfere each other and at worst cause tuning fails or bad reception quality. If the demod driver does gate_ctrl before setting up tuner parameters, and the tuner does another I2C enable, it will deadlock forever when gate_ctrl is wrapped into the mutex_lock. This adds a flag and a conditional before triggering gate_ctrl in the demodulator driver. Signed-off-by:

I would like to replace Kyungmin Park, who is no longer interested in maintaining S5P-CEC driver. I have access to various Exynos boards. I also already did some tests of this driver and helped enabling it on various Exynos boards. The driver itself is no longer in staging, so lets fix the path too and add DT bindings file pattern match. Also change the mailing list from ARM generic to Samsung SoC specific to get more attention and easier review in the future. Signed-off-by:

There are multiple places where arrays or otherwise variable sized buffer are allocated through V4L2 core code, including things like controls, memory pages, staging buffers for ioctls and so on. Such allocations can potentially require an order > 0 allocation from the page allocator, which is not guaranteed to be fulfilled and is likely to fail on a system with severe memory fragmentation (e.g. a system with very long uptime). Since the memory being allocated is intended to be used by the CPU exclusively, we can consider using vmalloc() as a fallback and this is exactly what the recently merged kvmalloc() helpers do. A kmalloc() call is still attempted, even for order > 0 allocations, but it is done with __GFP_NORETRY and __GFP_NOWARN, with expectation of failing if requested memory is not available instantly. Only then the vmalloc() fallback is used. This should give us fast and more reliable allocations even on systems with higher memory pressure and/or more fragmentation, while still retaining the same performance level on systems not suffering from such conditions. While at it, replace explicit array size calculations on changed allocations with kvmalloc_array(). Purposedly not touching videobuf1, as it is deprecated, has only few users remaining and would rather be seen removed instead. Signed-off-by:

The davinci VPIF is a single hardware block, but the existing driver is broken up into a common library (vpif.c), output (vpif_display.c) and intput (vpif_capture.c). When migrating to DT, to better model the hardware, and because registers, interrupts, etc. are all common,it was decided to have a single VPIF hardware node[1]. Because davinci uses legacy, non-DT boot on several SoCs still, the platform_drivers need to remain. But they are also needed in DT boot. Since there are no DT nodes for the display/capture parts in DT boot (there is a single node for the parent/common device) we need to create platform_devices somewhere to instantiate the platform_drivers. When VPIF display/capture are needed for a DT boot, the VPIF node will have endpoints defined for its subdevs. Therefore, vpif_probe() checks for the presence of endpoints, and if detected manually creates the platform_devices for the display and capture platform_drivers.

As long as only one CODA context is running we get alternating device_run() and wait_for_completion() calls, but when more then one CODA context is active, other VDOA slots can be inserted between those calls for one context. Make sure to wait on job completion before running a different context and before destroying the currently active context. Signed-off-by:

This implements a simple handler for the case where decode did not finish sucessfully. This might be helpful during normal streaming, but for now it only handles the case where the context would deadlock with userspace, i.e. userspace issued DEC_CMD_STOP and waits for EOS, but after the failed decode run we would hold the context and wait for userspace to queue more buffers.

This adds support for V4L2_CID_MIN_BUFFERS_FOR_CAPTURE get control in venus decoder, it is usable in case when the userspace wants to know minimum capture buffers before calling request_buf for capture queue in mem2mem drivers. Also this will fix an issue found gstreamer v4l2videodec element, i.e. the video decoder element cannot continue because the buffers are insufficient. Signed-off-by:

This adds Venus driver Makefile and changes v4l2 platform Makefile/Kconfig in order to enable building of the driver. Note that in this initial version the COMPILE_TEST-ing is not supported because the drivers specific to ARM builds are still in process of enabling the aforementioned compile testing. Once that disadvantage is fixed the Venus driver compile testing will be possible with follow-up changes. Signed-off-by:
