ov5693 and atomisp (, which is needed for ov5693 for now) modules once existed in staging tree until 4.17, removed in 4.18 due to a lack of progress. I happened...

It seems that, at least, ov7251 is already [upstream](https://github.com/torvalds/linux/blob/master/drivers/media/i2c/ov7251.c). I built the module with this config: ``` # CONFIG_MEDIA_SUBDRV_AUTOSELECT is not set CONFIG_VIDEO_OV7251=m ``` However, not probed at all. No...

I found a bug report of the ov7251 on Kernel.org Bugzilla. - [204697 – On HP Elite x2 1013 G3 ipu3-imgu driver can't open stream from ov7251 sensor](https://bugzilla.kernel.org/show_bug.cgi?id=204697)

Does anyone know why the upstream driver ov7251 does not probe the device at all as mentioned before? and libcamera does not enumerate any cameras: ```bash $ sudo cam -l...

(@ other Surface owners: Surface 3 does not use IPTS) Yes, I have the same issue on my Surface 3. On dmesg, these messages will be printed repeatedly: ``` kern...

Interestingly, on Arch Linux stock 5.1.15 kernel (`5.1.15-arch1-1-ARCH`), I have this issue. So, the cause of this issue might be a kernel config. I'll try kernels which are built with...

I built Arch Linux 5.1.15 kernel with the jakeday 5.1 config and touch input is working even after suspend. I looked into the debug output and it uses PIO mode...

Small update. Finding what kernel configs determine to use DMA/PIO is difficult. Anyway, I think we should fix this issue on rather touchscreen driver side. So, I'll try to disable...

Update: added parameter to switch DMA/PIO: surface3-spi: add parameter to disable DMA ```diff From 08821ab4a4bab74eb42cc949b6a65ec4e819327a Mon Sep 17 00:00:00 2001 From: kitakar5525 Date: Fri, 6 Dec 2019 23:10:30 +0900 Subject:...

Sorry for taking a long time, but I feel the patch is still not so clean for everyone to be merged into qzed/linux-surface. Hmm… I'll try to ask qzed.
