Ov5640 camera bringup on qcomlt-5.15 kernel with platform(820)

Products Support DragonBoard 820c
#1

We are trying to enable ov5640 camera on qcomlt-5.15 kernel. In the device tree(apq8096-db820c.dtsi) we do not see any default nodes present w.r.t camera sensor. Also, we see msm8996-pins.dtsi file is missing in the kernel.

Any ideas? if any camera sensor has been already validated on this qcomlt-5.15 kernel 820 SoM? If yes then the reference patch will be very useful for us.

Note:
On the same platform(820) with kernel 4.14, ov5640 sensor is working fine for us…

@robertfoss, isn’t ov5640 with 820 something you already tried in the past?

#3

I’ve only tried it with RB3 / SDM845

#4

@robertfoss this is w.r.t kernel 5.15? If yes, where can I see these changes.

#5

@Loic Thank you so much for quick response. Can I know is there any camera sensor is validated with platform(820) with kernel 5.15?

I am able to get Snapshot and live preview working on qcomlt-5.15 kernel 820 SoM. With the default ov5640 driver itself I was able to get these things working fine. I used below configs:

sudo media-ctl -d /dev/media0 -l ‘“msm_csiphy0”:1->“msm_csid0”:0[1],“msm_csid0”:1->“msm_ispif0”:0[1],“msm_ispif0”:1->“msm_vfe0_rdi0”:0[1]’
sudo media-ctl -d /dev/media0 -V ‘“ov5640 4-003b”:0[fmt:UYVY8_2X8/1920x1080 field:none],“msm_csiphy0”:0[fmt:UYVY8_2X8/1920x1080 field:none],“msm_csid0”:0[fmt:UYVY8_2X8/1920x1080 field:none],“msm_ispif0”:0[fmt:UYVY8_2X8/1920x1080 field:none],“msm_vfe0_rdi0”:0[fmt:UYVY8_2X8/1920x1080 field:none]’

Currently I am trying to use msm_vfe0_pix instead of msm_vfe0_rdi0. But I am facing below error’s

Below command’s I am trying for Snapshot:
