Re: [PATCH 13/13] media: qcom: camss: Add support for VFE hardware version Titan 780

Hi Vladimir,


Thanks for the confirmation, even though I add the rup_update and
buf_done function in later commits, it is still called in platform
specific code(camss-vfe-780.c), so I will keep as it is done today.

let it be so.

I have another ask about it, please move new camss_reg_update() out from
camss.c into camss-csid.c, and camss_buf_done() from camss.c into camss- vfe.c


The cross direct call has been removed by below commit, so it looks strange if I add the cross direct call.

media: qcom: camss: Decouple VFE from CSID

I use the v4l2_subdev_notify to do the cross communication in v1 and v2 series, but Bryan said, "The subdev notify is I think not the right fit for this purpose within our driver.". Then I add an internal notify interface in camss structure, but Bryan suggested to use direct call, so I add these functions directly in camss.c

Thanks,
Depeng
