2019-05-18media: prefix header search paths with $(srctree)/Masahiro Yamada1-2/+2
Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks. Having whitespaces after -I does not matter since commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter").

Pull drm updates from Dave Airlie: "This has two exciting community drivers for ARM Mali accelerators. Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging.

Restart the CSI-2 link if the CSI-2 receiver detects an error during reception. The driver did nothing when a link error happened and the data flow simply stopped without the user knowing why. Change the driver to try and recover from errors by restarting the link and informing the user that something is not right. For obvious reasons it's not possible to recover from all errors (video source disconnected for example) but in such cases the user is at least informed of the error and the same behavior of the stopped data flow is retained.

The "b->index" is a u32 the comes from the user in the ioctl. It hasn't been checked. We aren't supposed to use it but we're instead supposed to use the value that gets written to it when we call videobuf_dqbuf(). The videobuf_dqbuf() first memsets it to zero and then re-initializes it inside the videobuf_status() function. It's this final value which we want. Hans Verkuil pointed out that we need to check the return from videobuf_dqbuf(). I ended up doing a little cleanup related to that as well.

2019-05-08media: atmel: atmel-isc: limit incoming pixels per frameEugen Hristev2-0/+53
This will limit the incoming pixels per frame from the sensor. Currently, the ISC will stop sampling the frame only when the vsync/hsync are detected. If we misconfigure the resolution in the sensor w.r.t. resolution in the ISC, the buffer used for DMA in the ISC will be smaller than the number of pixels that the ISC DMA engine will copy. In this case it happens that the DMA will overwrite parts of the memory which should not be written, leading to memory corruption. To avoid this situation, use the PFE CFG1 and PFE CFG2 registers, which crop the incoming frame to the resolution that we configure. This way the DMA engine will never write more data than we expect it to.

2019-04-22media: platform: meson: Add Amlogic Meson G12A AO CEC Controller driverNeil Armstrong3-0/+796
The Amlogic G12A SoC embeds a second CEC controller with a totally different design. The two controller can work in the same time since the CEC line can be set to two different pins on the two controllers. This second CEC controller is documented as "AO-CEC-B", thus the registers will be named "CECB_" to differentiate with the other AO-CEC driver. Unlike the other AO-CEC controller, this one takes the Oscillator clock as input and embeds a dual-divider to provide a precise 32768Hz clock for communication. This is handled by registering a clock in the driver. Unlike the other AO-CEC controller, this controller supports setting up to 15 logical addresses and supports the signal_free_time settings in the transmit function. Unfortunately, this controller does not support "monitor" mode.

I previously added an RC_CORE dependency here, but missed the corner case of CONFIG_VIDEO_SECO_CEC=y with CONFIG_RC_CORE=m, which still causes a link error: drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_probe': seco-cec.c:(.text+0x1b8): undefined reference to `devm_rc_allocate_device' seco-cec.c:(.text+0x2e8): undefined reference to `devm_rc_register_device' drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_irq_handler': seco-cec.c:(.text+0xa2c): undefined reference to `rc_keydown' Refine the dependency to disallow building the RC subdriver in this case. This is the same logic we apply in other drivers like it.
