Logging of explicit out of memory messages is redundant since memory allocation failures produce a backtrace.

The common-clk core expects clk consumers to always call enable/disable in a balanced manner. The atomisp driver does not call gmin_flisclk_ctrl() in a balanced manner, so add a clock_on bool and skip redundant calls.

When I was supporting Rpi Camera Module on the ASUS Tinker board, I found this driver have some issues with rockchip's mipi-csi driver. It didn't place clock lane in LP-11 state before performing D-PHY initialisation. >From our experience, on some OV sensors, LP-11 state is not achieved while BIT(5)-0x4800 is cleared. So let's set BIT(5) and BIT(0) both while not streaming, in order to coax the clock lane into LP-11 state. 0x4800 : MIPI CTRL 00 BIT(5) : clock lane gate enable 0: continuous 1: none-continuous BIT(0) : manually set clock lane 0: Not used 1: used Signed-off-by:

This driver adds support for the Tegra CEC IP. It is based on the NVIDIA drivers/misc/tegra-cec driver in their 3.10 kernel. This has been converted to the CEC framework and cleaned up. Tested with my Jetson TK1 board. It has also been tested with the Tegra X1 in an embedded product. Note of warning for the Tegra X2: this SoC supports two HDMI outputs, but only one CEC adapter and the CEC bus is shared between the two outputs. This is a design mistake and the CEC adapter can control only one HDMI output. Never hook up both HDMI outputs to the CEC bus in a hardware design: this is illegal as per the CEC specification. The CEC bus can be shared between multiple inputs and zero or one outputs, but not between multiple outputs. Signed-off-by:

The imx274 is a Sony CMOS image sensor that has 1/2.5 image size. It supports up to 3840x2160 (4K) 60fps, 1080p 120fps. The interface is 4-lane MIPI CSI-2 running at 1.44Gbps each. This driver has been tested on Xilinx ZCU102 platform with a Leopard LI-IMX274MIPI-FMC camera board. Support for the following features: -Resolutions: 3840x2160, 1920x1080, 1280x720 -Frame rate: 3840x2160 : 5 – 60fps 1920x1080 : 5 – 120fps 1280x720 : 5 – 120fps -Exposure time: 16 – (frame interval) micro-seconds -Gain: 1x - 180x -VFLIP: enable/disabledrivers/media/i2c/imx274.c -Test pattern: 12 test patterns Signed-off-by:Leon Luo <leonl@leopardimaging.com> Tested-by:

This addresses the wrong behavior of decoder stop command by rewriting it. These new implementation enqueue an empty buffer on the decoder input buffer queue to signal end-of-stream. The client should stop queuing buffers on the V4L2 Output queue and continue queuing/dequeuing buffers on Capture queue. This process will continue until the client receives a buffer with V4L2_BUF_FLAG_LAST flag raised, which means that this is last decoded buffer with data. Signed-off-by:
