[git:media_stage/master] media: qcom: camss: Pass line_num from compat resources
This is an automatic generated email to let you know that the following patch were queued: Subject: media: qcom: camss: Pass line_num from compat resources Author: Bryan O'Donoghue Date:Mon Sep 25 16:46:56 2023 +0100 line_num indicates the number of RDI - raw data interface channels which are associated with a given IFE/VFE - image/video front end. On several SoCs the RDI number is not static for each VFE - for example on sm8250 VFE Lite has four RDIs where regular VFE has three. Assigning line_num statically in the subdev_init() phase initialises each VFE to the lower number, meaning in practical terms that we are lobbing off one RDI on some VFEs. Interrupt handling uses static for (i = RDI0; i < RDI2; i++) {} in some of our VFE blocks but this can't work for situations where we have a mixture of VFE @ 3 RDI and VFE-lite @ 4 RDI blocks. First step to remediate is to pass line_num from a compat string controlled data-structure and do so on a per-VFE basis. Later patches will assign the correct number of RDI blocks per VFE.
