Just noticed this too.
You're configuring the CSID routing here for each enabled VC but, you should only do that once @ the top level
->
__csid_configure_top(csid);
/* Loop through all enabled VCs and configure stream for each */
for (i = 0; i < MSM_CSID_MAX_SRC_STREAMS; i++)
if (csid->phy.en_vc & BIT(i)) {
__csid_configure_rdi_stream(csid, enable, i);
__csid_configure_rx(csid, &csid->phy, i);
__csid_ctrl_rdi(csid, enable, i);
}
