* media: cx231xx: convert to the vb2 frameworkHans Verkuil2019-10-017-1109/+407
| | | | | | | | | | This patch converts the cx231xx driver to the vb2 framework. Since you can't do a partial conversion this is a big-bang patch, i.e. large and hard to review. I never found a way around this.

* media: cec-gpio: add notifier supportHans Verkuil2019-10-012-9/+33
| | | | | | | | | | | | | | | | | | | | | | 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 <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

| | | | | | | | | | | | | | | | | | Since the uapi does not contain the num_ref_idx_active_override_flag, drivers for decoders that do not parse slices themselves don't know how to choose between the num_ref_idx_l[01]_default_active and the num_ref_idx_l[01]_active override fields. Instead, userspace must set the override fields to the default values if the slice does not have the num_ref_idx_active_override flag set. The drivers will then always enable the override internally and ignore the default fields completely. Clarify this requirement in the API documentation.

* media: cedrus: fix various format-related compliance issuesHans Verkuil2019-10-013-25/+14
| | | | | | | | | | | | | | | | | | | | | | | Initialize the context on open() with valid capture and output formats. It is good practice to always have valid formats internally. This solves one vb2 warning in the kernel log where the sizeimage value of the output format was 0 when requesting buffers, which is not allowed. It also simplifies the g_fmt ioctl implementations since they no longer have to check if a valid format was ever set. cedrus_prepare_format() now also validates sizeimage for the output formats, ensuring userspace can't set it to 0 since that would cause the same vb2 warning. Finally remove the sizeimage == 0 check in cedrus_try_fmt_vid_out() since cedrus_prepare_format() will now adjust this value.

* media: am437x-vpfe: TRY_FMT ioctl is not really trying anythingBenoit Parrot2019-10-012-171/+171
| | | | | | | | | | | | | | | | | | The try_fmt was not actually trying out the provided format but merely returning the current format basically like get_fmt. In addition set_fmt should first invoked try_fmt to validate the given format before applying it to the hardware. To fix all of these the whole get/try/set ioctl functions had to be reworked. When calculating the bytesperline/stride and sizeimage format member we don't need to locally store the current value of bytesperpixel as it can easily get derived dynamically.

* media: am437x-vpfe: Wait for end of frame before tear-downBenoit Parrot2019-10-012-26/+29
| | | | | | | | | | | | | | | | | | | | | We were originally attempting to stop all processing as soon as possible, but the in-progress DMA operation cannot be canceled. This led to the module being in a busy state and prevented proper power management functionality. The existing implementation would attempt to clean things up by waiting up to 50ms. However when receiving video frame at 15fps or lower, it meant an inter frame arrival rate of 66.6 ms or higher. In such cases upon tear down the following message could be seen: omap_hwmod: vpfe0: _wait_target_disable failed This patch fixes this issue by adding a stopping state where we would wait for the next Vsync before disabling the hardware.
