media: sun4i: Add H3 deinterlace driver

2019-10-24T22:07:59Z

Allwinner H3 SoC contains deinterlace unit, which has several modes of operation - bypass, weave, bob and mixed (advanced) mode. I don't know how mixed mode works, but according to Allwinner it gives best results, so they use it exclusively. Currently this mode is also hardcoded here. For each interleaved frame queued, this driver produces 2 deinterlaced frames. Deinterlaced frames are based on 2 consequtive output buffers, except for the first 2, where same output buffer is given to peripheral as current and previous. There is no documentation for this core, so register layout and fixed values were taken from BSP driver. I'm not sure if maximum size of the image unit is capable to process is governed by size of "flag" buffers, frequency or it really is some HW limitation. Currently driver can process full HD image in ~15ms (7.5ms for each capture buffer), which allows to process 1920x1080@60i video smoothly in real time.

media: cec-gpio: Use CONFIG_PREEMPTION

2019-10-24T21:37:20Z

CONFIG_PREEMPTION is selected by CONFIG_PREEMPT and by CONFIG_PREEMPT_RT. Both PREEMPT and PREEMPT_RT require the same functionality which today depends on CONFIG_PREEMPT. Switch the Kconfig dependency to CONFIG_PREEMPTION. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: venus: Use on-chip interconnect API

2019-10-02T13:58:27Z

This aims to add a requests for bandwidth scaling depending on the resolution and framerate (macroblocks per second). The exact value of the requested bandwidth is get from a pre-calculated tables for encoder and decoder. Acked-by: Georgi Djakov Signed-off-by: Stanimir Varbanov Signed-off-by: Mauro Carvalho Chehab

media: cec-gpio: add notifier support

2019-10-01T20:21:14Z

Add support for cec-notifier to the cec-gpio driver. This makes it possible to associate the CEC gpio pin with an HDMI connector. This feature was always documented in the cec-gpio bindings: Documentation/devicetree/bindings/media/cec-gpio.txt But support for the hdmi-phandle property was never actually implemented in this driver. This patch adds support for this property. It also fixes a few incorrect error returns in the probe() function, which skipped the call to cec_delete_adapter(). Tested on a Raspberry Pi 3B with a modified vc4 driver. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: sunxi: Refactor the Makefile and Kconfig

2019-08-23T10:29:05Z

The Makefile and Kconfig for the sun6i CSI driver are included in the main Makefile / KConfig file. Since we're going to add a new CSI driver for an older chip, and the Cedrus driver eventually, it makes more sense to put those in our directory.
