media: tegra-cec: add Tegra HDMI CEC driver

2017-10-27T13:48:57+00:00

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: Hans Verkuil Acked-by: Thierry Reding Signed-off-by: Mauro Carvalho Chehab

[media] rockchip/rga: v4l2 m2m support

2017-10-16T23:23:55+00:00

Rockchip RGA is a separate 2D raster graphic acceleration unit. It accelerates 2D graphics operations, such as point/line drawing, image scaling, rotation, BitBLT, alpha blending and image blur/sharpness The driver supports various operations from the rendering pipeline. - copy - fast solid color fill - rotation - flip - alpha blending The code in rga-hw.c is used to configure regs according to operations The code in rga-buf.c is used to create private mmu table for RGA.

media: cec-gpio: add HDMI CEC GPIO driver

2017-09-23T11:51:44+00:00

Add a simple HDMI CEC GPIO driver that sits on top of the cec-pin framework. While I have heard of SoCs that use the GPIO pin for CEC (apparently an early RockChip SoC used that), the main use-case of this driver is to function as a debugging tool. By connecting the CEC line to a GPIO pin on a Raspberry Pi 3 for example it turns it into a CEC debugger and protocol analyzer. With 'cec-ctl --monitor-pin' the CEC traffic can be analyzed. But of course it can also be used with any hardware project where the HDMI CEC line is hooked up to a pull-up gpio line. In addition this has (optional) support for tracing HPD changes if the HPD is connected to a GPIO. Signed-off-by: Hans Verkuil Reviewed-by: Linus Walleij Signed-off-by: Mauro Carvalho Chehab

media: platform: Add Amlogic Meson AO CEC Controller driver

2017-08-09T14:45:26+00:00

The Amlogic SoC embeds a standalone CEC controller, this patch adds a driver for such controller. The controller does not need HPD to be active, and could support up to max 5 logical addresses, but only 1 is handled since the Suspend firmware can make use of this unique logical address to wake up the device. The Suspend firmware configuration will be added in an other patchset.

media: venus: fix compile-test build on non-qcom ARM platform

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.
