ISL79987 support with current SDK

mod42 — Mon, 22 Mar 2021 10:08:36 GMT

I tried to port the patches in [1] to the current SDK (5.4.70_2.3.0) which we use on the

iMX8QXP MEK (and on our custom hardware). But there is no function mxc_isi_initialize_capture_subdev

which is called in 0001-ISI-Add-de-interlace-support.patch. So manually applying the patch is not

possible. Is there a version of the patches for the current SDK?

Hello,

I'm not aware of an update for this patch, but it could be used as reference to modify the ISI driver in newer releases like 5.4.70, the driver was moved from drivers/media/platform/imx8/ to drivers/staging/media/imx

https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/staging/media/imx?h=imx_5.4.70_2.3.0

Best regards,
Aldo.

The patches didn't apply easily. I had to delay the porting to a later stage. We are currently in board bringup. But the ISL79987 driver works well and we can capture video. Deinterlacing is not as important as veryfying that the hardware works.
