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:

Using the ARRAY_SIZE macro improves the readability of the code. Also, it is useless to use a variable to store this constant calculated at compile time. Found with Coccinelle with the following semantic patch: @r depends on (org || report)@ type T; T[] E; position p; @@ ( (sizeof(E)@p /sizeof(*E)) | (sizeof(E)@p /sizeof(E[...])) | (sizeof(E)@p /sizeof(T)) ) 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:

To improve the readability of code, split the format array into two, one for the format description, other for the register configuration. Meanwhile, add the flag member to indicate the format can be achieved from the sensor or be produced by the controller, and rename members related to the register configuration. Also add more formats support: GREY, ARGB444, ARGB555 and ARGB32. Signed-off-by:

A software write operation to the ISC_CLKEN or ISC_CLKDIS register requires double clock domain synchronization and is not permitted when the ISC_SR.SIP is asserted. So add the .prepare and .unprepare ops to make sure the ISC_CLKSR.SIP is unasserted before the write operation to the ISC_CLKEN or ISC_CLKDIS register. Signed-off-by:

Instead of relying on a mix of runtime PM and the s_power() callback, drop the s_power() callback altogether and use runtime PM solely. As device access is required during device power-on and power-off sequences, runtime PM alone cannot tell whether the device is available. Thus the "active" field is introduced in struct smiapp_sensor to tell whether it is safe to write to the device. Consequently there is no need to power on the device whenever a file handle is open. This functionality is removed as well. The user may still control the device power management through sysfs. Autosuspend remains enabled, with 1 s delay. Signed-off-by:
